            Mathematical Mesh 3.0 Part V: Protocol Reference
                   draft-hallambaker-mesh-protocol-14

Abstract

   The Mathematical Mesh 'The Mesh' is an end-to-end secure
   infrastructure that facilitates the exchange of configuration and
   credential data between multiple user devices.  The core protocols of
   the Mesh are described with examples of common use cases and
   reference data.

1.  Introduction

   This document describes the Mesh Service protocol supported by Mesh
   Services, an account-based protocol that facilitates exchange of data
   between devices connected to a Mesh profile and between Mesh
   accounts.

   Mesh Service Accounts support the following services:

Internet-Draft           Mesh Protocol Reference            October 2022


   *  Provides the master persistence store for the Catalogs and Spools
      associated with the account.

   *  Enables synchronization of Catalogs and Spools with connected
      devices.

   *  Enforces access control on inbound Mesh Messages from other users
      and other Mesh Services.

   *  Authenticates outbound Mesh Messages, certifying that they comply
      with abuse mitigation policies.

   A Mesh Profile MAY be bound to multiple Mesh Service Accounts at the
   same time but only one Mesh Service Account is considered to be
   authoritative at a time.  Users may add or remove Mesh Service
   Accounts and change the account designated as authoritative at any
   time.

   The Mesh Services are build from a very small set of primitives which
   provide a surprisingly extensive set of capabilities.  These
   primitives are:

   Hello  Describes the features and options provided by the service and
      provides a 'null' transaction which MAY be used to establish an
      authentication ticket without performing any action,

   CreateAccount, DeleteAccount  Manage the creation and deletion of
      accounts at the service.

   Status, Download, Upload  Support synchronization of Mesh containers
      between the service (Master) and the connected devices (Replicas).

   Connect  Initiate the process of connecting a device to a Mesh
      profile from the device itself.

   Post  Request that a Mesh Message be transferred to one or more Mesh
      Accounts.

   Although these functions could in principle be used to replace many
   if not most existing Internet application protocols, the principal
   value of any communication protocol lies in the size of the audience
   it allows them to communicate with.  Thus, while the Mesh Messaging
   service is designed to support efficient and reliable transfer of
   messages ranging in size from a few bytes to multiple terabytes, the
   near-term applications of these services will be to applications that
   are not adequately supported by existing protocols if at all.

2.  Definitions

   This section presents the related specifications and standard, the
   terms that are used as terms of art within the documents and the
   terms used as requirements language.

2.1.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

2.2.  Defined Terms

   The terms of art used in this document are described in the _Mesh
   Architecture Guide_ [draft-hallambaker-mesh-architecture].

2.3.  Related Specifications

   The architecture of the Mathematical Mesh is described in the _Mesh
   Architecture Guide_ [draft-hallambaker-mesh-architecture].  The Mesh
   documentation set and related specifications are described in this
   document.

2.4.  Implementation Status

   The implementation status of the reference code base is described in
   the companion document [draft-hallambaker-mesh-developer].

3.  Mesh Protocols

   The Mesh specifies two separate types of protocol interactions:

   Mesh Service Protocol  A synchronous protocol supporting interactions
      between devices and a Mesh Service Host and between Mesh Service
      hosts.

   Mesh Messaging Protocol  An asynchronous protocol that supports
      interactions between devices connected to the same account and
      between accounts.

   The Mesh Messaging Protocol uses the Mesh Service Protocol as
   transport.  The Mesh Service Protocol in turn makes use of Reliable
   UDP Datagram (RUD) [draft-hallambaker-mesh-rud] for framing and
   authentication of individual requests and responses.  These RUS
   packets are in turn exchanged over either HTTPS (i.e. a Web Service)
   or directly over UDP.

   Mesh Services MUST support the HTTPS binding and MAY support the UDP
   binding.

4.  Mesh Service

   A Mesh Service is a minimally trusted service.  In particular a user
   does not need to trust a Mesh service to protect the confidentiality
   or integrity of most data stored in the account catalogs and spools.

   Unless the use of the Mesh Service is highly restricted, a user does
   need to trust the Mesh Service in certain respects:

   Data Loss  A service could refuse to respond to requests to download
      data.

   Integrity (Stale Data)  The use of Merkle Trees limits but does not
      eliminate the ability of a Mesh Service to respond to requests
      with stale data.

   Messaging  A service could reject requests to post messages to or
      accept messages from other mesh users.

      This risk is a necessary consequence of the fact that the Mesh
      Service Provider is accountable to other Mesh Service Providers
      for abuse originating from their service.

   Traffic analysis  A Mesh Service has knowledge of the number of Mesh
      Messages being sent and received by its users and the addresses to
      which they are being sent to or received from.

   The need to trust the Mesh Service in these respects is mitigated by
   accountability and the user's ability to change Mesh Service
   providers at any time they choose with minimal inconvenience.

   It is possible that some of these risks will be reduced in future
   versions of the Mesh Service Protocol but it is highly unlikely that
   these can be eliminated entirely without compromising practicality or
   efficiency.

4.1.  Data Model

   The design of the Mesh Service model followed a quasi-formal approach
   in which the system was reduced to schemas which could in principle
   be rendered in a formal development method but without construction
   of proofs.

   Like the contents of Mesh Accounts, a Mesh Service may be represented
   by a collection of catalogs and spools, for example:

   Account Catalog  Contains the account entries.

   Incident Spool  Reports of potential abuse

   Backup of the service MAY be implemented using the same container
   synchronization mechanism used to synchronize account catalogs and
   spools.

4.2.  Partitioning

   Mesh Services supporting a large number of accounts or large activity
   volume MAY partition the account catalog between one or more hosts
   using the usual tiered service model in which a front-end server
   receives traffic for any account hosted at the server and routes the
   request to the back-end service that provides the persistence store
   for that account.

   In addition, the Mesh Service Protocol supports a 'direct connection'
   partitioning model in which devices are given a DNS name which MAY
   allow for direct connection to the persistence host or to a front-end
   service offering service that is in some way specific to that
   account.

5.  Protocol Bindings

   The protocol binding maps the abstract protocol definition specified
   in this document to the network protocol format.

   *  Discovery of network services.

   *  Construction of the payload data by serializing request and
      response messages.

   *  Authentication of the payload data.

   *  Confidentiality controls to protect against traffic analysis

   Currently only one protocol binding is specified: JSON-BCD
   Application Binding [draft-hallambaker-jsonbcd] over Reliable User
   Datagram (RUD) [draft-hallambaker-mesh-rud].

   *JSON-BCD Application Binding* specifies the means by which data
   types such as 'integer' and 'datetime' etc. given in this document
   are serialized using JSON/JSON-B encoding.

   *Reliable User Datagram* offers a presentation layer over a choice of
   HTTP or UDP transport.

6.  Mesh Service Operations

   The Mesh Service operations are divided into the following functional
   groups:

   Service Description  Describes the service.

   Account Management  Operations used to create, reclaim, and delete
      accounts.

   Persistence Store Management  Operations used to synchronize
      persistence store data across connected devices.  [May be replaced
      in a future revision]

   Device Connection  Operations used by devices requesting connection
      to the account.

   Publication  Operations allowing a watched document to be posted to
      the service and claims made on the document returned to a device.

   Cryptographic  Cryptographic operations, including threshold
      operations performed by the service.

   Messaging  Exchange of messages between Mesh Services.

6.1.  Service Description

   The Hello transaction is used to determine the features supported by
   the service and obtain the service profile.

   The request payload only specifies that is is a request for the
   service description:

   {
     "HelloRequest":{}}

   The current revision of the specification is designed for small scale
   deployments in which the service is provided by a single host.  The
   approach will require revision in future versions to fully support a
   service being provided by multiple hosts with accounts being
   transferred between the hosts to allow balancing of load.

6.2.  Account Management

   There are three account management operations:

   BindAccount  Create an account bound to a service address.

   UnbindAccount  Delete an account bound to a service address

   RecoverAccount  [TBS] Reclaim an account using a recovered primary
      secret.

   The BindAccount operation is used to create User and Group accounts.
   Currently, these account types are distinct.  This may change in
   future releases.

6.2.1.  Bind Account

   A User Account is bound to a Mesh Service by completing a BindAccount
   operation with the service.

   The BindAccount transaction is unique in that it can fail to complete
   for reasons that are outside the scope of the Mesh specifications.
   Creation of an account might require payment to be made or
   authentication of the user's credentials.  It is thus quite normal
   for the result of a CreateRequest to be the account being created in
   an 'on hold' state which can only be changed out of band.

   If the request is at least partially successful, a BindResponse
   message is returned.  In the case of partial success, a description
   of the request status and link to a Web page providing further
   details MAY be returned.

   The request payload contains all the information needed to create the
   account:

   *  The account address

   *  The account profile

   Since there is no Access Catalog until the account is created, the
   Bind Account request and subsequent requests used to initialize the
   access catalog for the account MUST be authenticated by the Account
   Authentication key.

   Alice requests creation of the account alice@example.com.  The
   request payload is:

   It is likely that a future revisions of the specification will
   specify the host(s) to which future account service operations are to
   be directed.  This would allow the account management operations to
   be separated from the account maintenance operations without
   requiring the traditional tiered architecture in which every
   interaction with a service is first routed to a host that cannot
   perform the required action so that it can be directed to the host
   that can.

6.2.1.1.  Bind Group Account

   Mesh Group Accounts are created in the same manner as user accounts
   except that the ProfileGroup is specified.

6.2.1.2.  Account Recovery

   Should all the administration devices be lost, an account MAY be
   recovered by the process of recovering the profile master secret and
   using it to access the account through the account authentication
   key.

6.2.2.  Unbind Account

   An account registration is deleted using the UnbindAccount
   transaction.

6.2.2.1.  Account Transfer

   Should a user wish to transfer their account to a new service
   provider, they first use the Bind Account operation to bind the
   account to the new service provider, then populate the account entry
   at the new account using the account authentication key.

   Only after the new account binding has been completed and is ready
   for use, is the unbind operation used to delete the account entry at
   the old service provider.

   Future versions of the protocol will elaborate on this mechanism so
   that the change of address can be signaled to connected devices and
   parties sending messages to the account.

6.2.3.  Account Recovery and Transfer.

   Account recovery is necessary in the case that user has lost control
   of every administration device connected to the account and must re-
   create the account profile and bind a new set of administrative
   devices.  Account transfer is the process of unbinding an account
   from one service and rebinding it to a new one.

   These capabilities are both critical to the long term success of the
   Mesh but have been deleted from the current revision of the
   specification as their implementation is interdependent on the
   architecture of the callsign registry.

6.3.  Persistence Store Management

   All the state associated with a Mesh profile is stored as a sequence
   of DARE Messages in a Dare Container.  The Mesh Service holding the
   master copy of the persistence stores and the devices connected to
   the profile containing complete copies (replicas) or partial copies
   (redactions).

   Thus, the only primitive needed to achieve synchronization of the
   profile state are those required for synchronization of a DARE
   Container.  These steps are:

   *  Obtain the status of the catalogs and spools associated with the
      account.

   *  Download catalog and spool updates

   *  Upload catalog updates.

   To ensure a satisfactory user experience, Mesh Messages are
   intentionally limited in size to 32 KB or less, thus ensuring that an
   application can retrieve the most recent 100 messages almost
   instantaneously on a high bandwidth connection and without undue
   delay on a slower one.

6.3.1.  Status

   The status transaction returns the status of the containers the
   device is authorized to access for the specified account together
   with the updated Device Connection Entry if this has been modified
   since the entry presented to authenticate the request was issued.

   Alice adds an entry to her bookmark catalog.  Before the bookmark can
   be added, the device synchronizes to the service.  The
   synchronization process begins with a request for the status of all
   the stores associated with the account that it has access rights for:

   {
     "StatusRequest":{
       "CatalogedDeviceDigest":"MAC5-ZJWC-FFYC-2KIO-YYOE-OO43-OZ"}}

   If the account has a very large number of stores, the device might
   only ask for the status of specific stores of interest.

   The response specifies the status of each store specifying the index
   and Merkle tree apex digest values for each:

6.3.2.  Download

   The download transaction returns a collection of entries from one or
   more containers associated with the profile.

   The service MAY limit the number of entries returned in an individual
   response for performance reasons.

   The previous status operation has reported that a new envelope has
   been added to the credential store.  The device requests this data
   from the service:

   Future: The current implementation of the download operation is
   limited by the capabilities of the HTTP binding of the RUD transport.
   A future binding allowing operations that consist of a single request
   followed by a sequence of responses will allow much greater
   flexibility.

   Future versions of the protocol may support optional filtering
   criteria so that the service only returns objects matching specific
   criteria and/or only return certain parts of the selected messages.

6.3.3.  Transact

   The transact transaction appends envelopes to one or more stores.
   The operation is atomic, that is either all the changes specified
   will be made to the stores or none will.  This ensures that
   simultaneous attempts to update a store do not result in race
   conditions allows Mesh stores to provide ACID (Atomicity,
   Consistency, Isolation, Durability) properties to the applications
   they serve.

   Clients SHOULD check to determine if updates to a container conflict
   with pending updates on the device waiting to be uploaded.  For
   example, if a contact that the user modified on the device attempting
   to synchronize was subsequently deleted.  The means of resolving such
   conflicts is not in the scope of this specification.

   Each update to a catalog or container specifies the expected
   container index and apex digest.  This provides a strong guarantee of
   consistency.  The service MUST verify each update to check that the
   Merkle Tree values specified are consistent with the store entries
   and that the signature on the apex value (if specified) is valid and
   correct.

   Services MAY impose limits on the size and number of additions
   performed in response to a TransactRequest message to ensure that
   processing time does not degrade performance for other users.

   The request payload specifies the data to be appended to the stores.

6.4.  Device Connection

   In order to support the wide range of affordances supported by
   devices, four device connection interactions are currently specified.
   The use of these mechanisms is described in
   [draft-hallambaker-mesh-architecture] and the interactions themselves
   are described in section ??? following.

   Device connection operations are always issued by a device requesting
   connection to a Mesh account and must therefore be authenticated
   under the device profile rather than the account profile.  Two device
   connection operations are currently defined:

   Connect  Requests connection to the account.

   Complete  Polls for completion of a connection request.

Internet-Draft           Mesh Protocol Reference            October 2022


   Since the second operation is merely polling for completion of the
   transaction requested by the first, it is likely that these will be
   combined in a future revision of the specification.

6.4.1.  Connect

   If the connection request is initiated by the device being connected,
   the device constructs a RequestConnection message which is posted to
   the Mesh Service using the Connect operation.

   If the Connect operation is accepted (i.e. the service determines it
   is not abuse), the service constructs an AcknowledgeConnection
   message which is forwarded to the inbound spool of the account to
   which connection is requested.  The requesting device receives a copy
   of the AcknowledgeConnection message and the profile of the account
   it is requesting connection to.

   As described in the following section, the AcknowledgeConnection
   message contains the request details presented by the device and a
   nonce value generated by the service.  This nonce value is used to
   compute the witness value that will be used for mutual authentication
   of the device and account.

   The connect request is made to the service, not the account.  The
   payload contains the enveloped connection request:

6.4.2.  Complete

   The complete operation is used to complete the binding of a device to
   the account regardless of whether the operation is initiated by the
   administration device or the connecting device.

   The complete request is made to the service, not the account.  The
   payload specifies the account the device is requesting completion for
   and the identifier of the completion message.

6.5.  Publication

   [Future: Consider eliminating this mechanism entirely and instead
   using messaging flows.  The means of achieving this should become
   better apparent when the problem of publishing large messages via a
   pull mechanism is considered.]

   The Publication mechanism allows content to be published through a
   Mesh Account and retrieved by means of the EARL mechanism described
   in Uniform Data Fingerprint [draft-hallambaker-mesh-udf].  This
   mechanism is used in certain flows supported by the Mesh Device
   Connection and Contact Exchange functions.  There are two operations:

   Claim  Post a claim to a published document

   PollClaim  Check to see if a claim has been posted.

Internet-Draft           Mesh Protocol Reference            October 2022


   Content is published by appending an entry to an account's
   Publication catalog by means of a Transact operation.  The content
   may then be retrieved by issuing a claim to the account specifying
   the publication identifier that is authenticated under the value
   specified in the EARL.

   Use of the Publication catalog to post content necessarily requires
   that the content be smaller than the maximum message size imposed by
   the Mesh Service so that it can be uploaded to the service by means
   of a Transact transaction.

   Publication of large data items will require modification of the
   protocol to support use of a detached message body.  Transfer of a
   detached message body is outside the scope of this document.

6.5.1.  Claim Transaction

   The claim transaction is used to post a claim to a document published
   by means of an EARL.  The claim interaction is used in the Static QR
   Code connection interaction but MAY be used for other purposes as
   required by Mesh applications.

   A claim is made by sending a ClaimRequest message to the service to
   which the publication is posted.  The service responds with a
   ClaimRespose message specifying the success or failure of the claim.

   A device is preconfigured during manufacture and a Device Description
   published to the EARL:

   The client claiming the publication creates a claim message
   specifying the resource being claimed and the address of the Mesh
   account making the claim.

   {
     "MessageClaim":{
       "PublicationId":"EBQM-KNOL-3JSA-7ODT-IDYR-4MIF-T372",
       "ServiceAuthenticate":"ADB6-LL6S-CFGJ-WEGN-ATQH-BIWP-C275",
       "DeviceAuthenticate":"AD5I-TWGR-5JLW-PYMH-6PQC-LVMO-MMBV",
       "MessageId":"NDMW-S56B-O3D3-NAK6-SKHF-3KHR-UCD7",
       "Sender":"alice@example.com",
       "Recipient":"maker@example.com"}}

   The message is signed by the claimant to make a RequestClaim to the
   service:

   The device waiting to be connected uses the PollClaim transaction to
   receive notification of a claim having been posted.

6.5.2.  PollClaim Transaction

   The PollClaim transaction is used to discover if a claim has been
   posted to a published document.

   When an authenticated, authorized request is made, the service
   responds with the latest claim posted to the publication.

   The device in the example above periodically polls the service to
   which the device description is published to find if a claim has been
   registered.

   The PollClaimRequest contains the account to which the document is
   published and the publication ID:

   {
     "PollClaimRequest":{
       "PublicationId":"EBQM-KNOL-3JSA-7ODT-IDYR-4MIF-T372",
       "TargetAccountAddress":"maker@example.com"}}

   The response returns the latest claim made as signed message:

6.6.  Cryptographic

   The Operate transaction is used to perform one or more cryptographic
   operations using private key material recorded in the Threshold
   Catalog.  Such operations typically represent one part of a threshold
   key operation divided between the service and a device connected to
   an account.

   As with all operations involving the Access catalog, the request MUST
   meet the authentication criteria specified by the catalog entry.
   These typically include the request being authenticated by a specific
   key.Key Agreement

   To make use of the access entry, a request is made that specifies the
   key share to be operated on and the public key parameters to perform
   the agreement with.

   The request payload:

   {
     "OperateRequest":{
       "AccountAddress":"groupw@example.com",
       "Operations":[{
           "CryptographicOperationKeyAgreement":{

             "KeyId":"MBVT-4N6Y-ARXQ-F3ZO-NEOS-EYNS-AG5N"}}
         ]}}

   The service checks to see if the request is authorized and if so,
   performs the operation and returns the result:

   *Future*: Currently, the access catalog is encrypted under the
   service encryption key.  It would be better to encrypt the catalog
   under an encryption key specified by the service during the process
   of account binding.  This would allow a service to assign a unique
   encryption key to each account and limit access to that key to the
   hosts servicing that specific account.

6.6.1.  Generate Key Shares

   Generation of threshold key shares is planned but not currently
   supported.

6.6.2.  Threshold Sign

   Threshold signature is planned but not currently supported.

6.7.  Messaging

   Mesh Messaging is an asynchronous messaging service that allows
   exchange of information between devices connected to a Mesh account
   and between Mesh users.

   To enable effective abuse mitigation, Mesh Messaging enforces a four-
   corner communication model in which all outbound and inbound messages
   pass through a Mesh Service which accredits and authorizes the
   messages on the user's behalf.

   (Artwork only available as svg: No external link available, see
   draft-hallambaker-mesh-protocol-14.html for artwork.)

               Figure 2: The Mesh Four Corner Messaging Model

   The Post transaction is only used to exchange messages between
   services.  The client sends and receives messages through
   interactions with the outbound and inbound spools of the account.

6.7.1.  Sender.

   To send a message, the client creates the Mesh Message structure,
   encapsulates it in a DARE Message and appends the message to the
   Outbound spool of the account using the Transact operation..

   The DARE Message MUST be signed under the account signature key.

   The Mesh Service receiving the message from the user's device MAY
   attempt immediate retransmission or queue it to be sent at a future
   time.  Mesh Services SHOULD forward messages without undue delay.

6.7.2.  Outbound Service

   The Post transaction forwarding the message to the destination
   service carries the same payload as the original request but is
   authenticated by the service forwarding it.  This authentication MAY
   be my means of either profile or ticket authentication.

   >>>> Unfinished ProtocolPostServiceService

   [Not Yet Implemented]





Hallam-Baker              Expires 26 April 2023                [Page 46]

Internet-Draft           Mesh Protocol Reference            October 2022


   After the message has been sent, the service updates the message
   status on the outbound spool.

   Services SHOULD implement Denial of Service mitigation strategies
   including limiting the maximum time taken to complete a transaction
   and refusing connections from clients that engage in patterns of
   behavior consistent with abuse.

   The limitation in message size allows Mesh Services to aggressively
   time out connections that take too long to complete a transaction.  A
   Mesh Service that hosted on a 10Mb/s link should be able to transfer
   20 messages a second.  If the service is taking more than 5 seconds
   to complete a transaction, either the source or the destination
   service is overloaded or the message itself is an attack.

   Imposing hard constraints on Mesh Service performance requires
   deployments to scale and apply resources appropriately.  If a service
   is attempting to transfer 100 messages simultaneously and 40% are
   taking 4 seconds or more, this indicates that the number of
   simultaneous transfers being attempted should be reduced.
   Contrawise, if 90% are completed in less than a second, the number of
   threads allocated to sending outbound messages might be increased.

6.7.3.  Inbound Service

   The inbound service MUST subject inbound messages to Access Control
   according to the credentials presented in the DARE Message payload.

   After verifying the signature and checking that the key is properly
   accredited in accordance with site policy, the service applies
   authorization controls taking account of:

   *  The accreditation of the sender

   *  The accreditation of the transmitting Service

   *  The type of Mesh Message being sent

   *  User policy as specified in their Contact Catalog

   *  Site policy.

6.7.4.  Recipient

   Messages are received by synchronizing the outbound spool.

7.  Access Control

   [This section to be expanded in future drafts]

   Access control is effected through the usual division of
   authentication and authorization.

   Authentication of operation requests is performed by the RUD layer
   [draft-hallambaker-mesh-rud] .

7.1.  Direct authorization

   Any request authenticated under the profile authentication key is
   authorized to perform any account operation without restriction.

7.2.  Access Catalog authentication

   If the authentication key presented has a matching Access Catalog
   entry, the device is authorized to perform operations as specified in
   that entry.

8.  Message Interactions

   Message interactions are asynchronous interactions that occur between
   devices connected to the same account or between accounts.

   All messages are signed by the sender and encrypted under the
   encryption key of the recipient if this is known to the sender.

8.1.  Message PIN Interaction

   The Message PIN Interaction is used to register and validate PIN
   codes used to authenticate certain transactions.  This interaction
   allows a PIN code issued by one device to be consumed by another
   allowing for greater convenience in managing devices or contact
   exchange.

   For example, Alice might delegate the PIN code issue privilege to her
   mobile device without delegating the administration privilege to that
   device.  This would allow Alice to use her mobile device to initiate
   the connection of a large number of devices to her Mesh as her house
   is being built and approve them later using her administrative
   device.

   Use of the Message PIN interaction is optional.  An application that
   issues a PIN code to authenticate a message MAY store the PIN value
   within the application without persisting it to external storage.

   Derivation of the SaltedPin, MessageId and Witness values from their
   respective inputs is described in the Schema Reference
   [draft-hallambaker-mesh-schema].

8.1.1.  Registration

   To register a PIN code to an Account, a device:

   *  Generates the PIN code value

   *  Calculates the SaltedPin value for the specified Action

   *  Calculates the PinId binding the specified SaltedPinto the
      Account.

   *  Creates and signs MessagePin containing the SaltedPin, Action and
      Account values with the MessageId value PinId.

   *  Appends the MessagePinvalue to the Administration Spool of the
      Account.

   Note that this construction provides limited protection against
   forgery attacks by a party with access to the MessagePin.  A party
   with such access can use it to construct the witness value required
   to authenticate a request.

   PIN Code values consist of an opaque sequence of octets represented
   as a UDF nonce value.  Codes are presented in canonical UDF form,
   i.e. Base32 encoding separated into groups of 4 characters.  The PIN
   value is converted to binary form for calculation of the SaltedPin,
   thus ensuring that the canonical form of the PIN value is used.

8.1.2.  Authentication

   The PIN Code value is passed out of band to a user who will enter it
   into a device to authenticate a request made to the issuer.

   A request that MAY be validated by means of a PIN is a subclass of
   MessagePinValidated and contains the following fields:

   AuthenticatedData  A DARE Envelope containing the data that is
      authenticated.

   ClientNonce  A nonce value used to prevent certain replay attacks.

   PinId  Digest value binding the SaltedPinto the Account.

   PinWitness  Witness value calculated as KDF (Device.UDF +

Internet-Draft           Mesh Protocol Reference            October 2022


      AccountAddress, ClientNonce)

   The device uses the PIN code and Action identifier corresponding to
   the desired request to calculate the SaltedPin value in the same
   manner as during registration.  This value is then used to calculate
   the PinId and PinWitness values.

8.1.3.  Validation

   The PIN code is validated by performing the steps of:

   *  Calculating the SaltedPin value from the PIN code and Action

   *  Calculating PinId from SaltedPin and Account

   *  Retrieving a MessagePin from the Administration spool with the
      MessageId PinId.

   *  Calculating the PinWitness value from SaltedPin, ClientNonce and
      AuthenticatedData and checking this matches the value specified in
      the message.

   *  Performing the requested action.

   *  Posting a Complete message to the Administration Spool of the
      Account marking the PIN code as used.

   This process can fail at multiple points resulting in different error
   results:

   PinInvalid  No PIN code is specified, the Pin code indicates an
      unsupported algorithm or the calculated PinWitness does not match
      the one specified by the request.

   PinUsed  The PIN code has been used previously.

   PinExpired  The PIN code is no longer valid.

   Note that in the case that an attempt is made to reuse a PIN, it is
   not automatically the case that the first use of the PIN was the one
   that was valid and only the second attempt was invalid.
   Implementations SHOULD alert the user to the attempted re-use so that
   this possibility can be considered and appropriate action taken.

8.1.4.  Example

   Alice connects a device using a QR code presented by her
   administrative device.

   The administration device creates a PIN code and records it to the
   Local spool.  The message specifies the salted pin value used to
   verify attempts to use the PIN, the action for which it is
   authorized.  Since this PIN has been issued to authorize a device
   connection, the roles for which the device are authorized as well.
   This allows the connection request to be accepted without asking for
   further input from the user.

       "Roles":["threshold"
         ],
       "MessageId":"ABFI-YEZB-HAEO-7LVM-E7VB-IWUC-YD3F"}}

8.2.  Completion Interaction

   Completion messages are dummy messages that are added to a Mesh Spool
   to mark a change the status of messages previously posted.  Any
   message that is in the inbound spool and has not been erased or
   redacted MAY be marked as read, unread or deleted.  Any message in
   the outbound spool MAY be marked as sent, received or deleted.

   Services MAY erase or redact messages in accordance with local site
   policy.  Since messages are not removed from the spool on being
   marked deleted, they may be undeleted by marking them as read or
   unread.  Marking a message deleted MAY make it more likely that the
   message will be removed if the sequence is subsequently purged.

   After using the PIN code to authenticate connection of a device in
   the previous example, the corresponding MessagePin is marked as
   having been used by appending a completion message to the Local
   spool.

   {
     "MessageComplete":{
       "References":[{
           "MessageId":"ABFI-YEZB-HAEO-7LVM-E7VB-IWUC-YD3F",
           "ResponseId":"MBI3-QJW4-3BIO-7SBZ-PEJP-E7NX-3W7E",
           "Relationship":"Closed"}
         ],
       "MessageId":"NCSO-MZMD-G2WJ-Z7NP-6ESO-X2GL-EXPP"}}

Internet-Draft           Mesh Protocol Reference            October 2022


   The completion message is added to the spool in the same upload
   transaction that adds the device to the device catalog.  This ensures
   that both operations occur or neither occurs.

8.3.  Contact Exchange Interaction

   The contact exchange interaction is used to support unilateral or
   mutual exchange of contact information.  Contact exchange has three
   functions in the Mesh:

   *  To exchange public key information to allow encryption of messages
      sent to and verification of signatures on messages sent from the
      contact subject.

   *  To exchange contact information allowing use of other
      communication protocols (e.g. telephone, SMS, xmpp, SMTP, OpenPGP,
      S/MIME, etc).

   *  To request that the recipient grant privileges to accept certain
      types of messages from the contact subject.

   Registration of the subject's contact information in a registry
   service eliminates the need for the first of these functions but not
   the other two.  To prevent abuse, every Mesh Message is subject to
   access control and a Mesh service will only accept a message from a
   sender if there is an entry in the Threshold Catalog of the account
   that expressly permits delivery of messages of the specified type
   that are authenticated by an authorized signature key.

   The communication of unsolicited information afforded by the contact
   exchange interaction is deliberately limited so that a majority of
   users can accept contact exchange requests without prior
   authorization.  It is however likely that some users will receive a
   considerable volume of requests forcing them to require contact
   requests be authorized through some form of third party
   accreditation.

8.3.1.  Remote

   The Remote Contact Exchange transaction consists of a sequence of
   MessageContact messages sent from the initiator to the responder,
   responder to the initiator, etc.  While there is in principle no
   limit on the number of messages exchanged, most exchanges will be
   completed in three exchanges or less:

   Initiator to Responder  Contains Initiator contact data without
      authentication context from the exchange.

   Responder to Initiator (optional)  Contains Responder contact data

      message.

   Initiator to Responder (optional)  Contains Initiator contact data

   The Mesh Contact Exchange transaction does not provide for validation
   of the contact information beyond the binding to the Mesh Account
   Address used to perform the exchange.

8.3.2.  PIN

   Contact exchange requests MAY be authenticated by a PIN code.
   Initial contact exchange requests SHOULD include a PIN code value
   that can be used to authenticate a response (if given).  PIN codes
   MAY also be exchanged out of band.

   A MessageContact authenticated by means of a PIN code is
   authenticated as described in the PIN Interaction section above.

8.3.3.  EARL

   A MessageContact message MAY be published as an EARL.  This allows
   contact data to be presented to the recipient on a printed document
   such as a business card in machine readable format such as a QR code.

8.4.  Group Invitation

   The GroupInvitation interaction is used to invite a recipient to join
   a Mesh Group.  The interaction is essentially a form of contact
   exchange except that a sender SHOULD NOT send group invitations
   unless there is an existing relationship.  Thus the 'first trust'
   issues intrinsic to the contact exchange interaction do not apply.

   The message specifies the group name and the contact entry for the
   group.  The contact entry includes the CapabilityDecryptServiced used
   to decrypt messages sent to the group when combined with information
   provided by the threshold service for the group.

   Receipt of a GroupInvitation message does not require a response.

8.5.  Confirmation Interaction

   The confirmation interaction consists of a RequestConfirmation
   message from the initiator followed by a ResponseConfirmation from
   the responder.

   The RequestConfirmation message specifies the action that is
   requested.

   The ResponseConfirmation message contains the enveloped
   RequestConfirmation message signed by the initiator and the
   disposition of the responder, Accept = true if the request is
   accepted and Accept = false otherwise.

   The service sends out the following request:

   {
     "RequestConfirmation":{
       "Text":"start",
       "MessageId":"NBGK-6BGU-5C5H-4WUR-OGDF-NZTH-ZLCW",

       "Recipient":"alice@example.com"}}

   Alice accepts the request and returns the following response:

9.  Device Connection Interactions

   Connection of a device to a Mesh Account combines synchronous and
   asynchronous elements and therefore uses a combination of Mesh
   Service Protocol and Mesh Messaging interactions.

   Four connection interactions are currently defined support connection
   of devices with different affordances:

   Witness Authenticated  For connecting devices that provide data entry
      and display affordances and are connected to a network.  The
      account the device is to be connected to is entered into the
      device which displays a witness code.  This code is then compared
      with a code displayed on the administration device to authenticate
      the request, after which both devices can complete the
      interaction.

   PIN Authenticated  A variation of the Witness Authenticated
      interaction in which the connection process is initiated by
      creating a PIN value which is communicated to the device by some
      out of band means and used to authenticate the connection request.

   Dynamic QR Code (PIN) Authenticated  For connecting devices that

Internet-Draft           Mesh Protocol Reference            October 2022


      provide a camera affordance.  The user sets the administration
      device into 'add device' mode, causing a QR code to be displayed.
      The QR code is scanned by the device being connected after which
      both devices can complete the interaction.  Implementation of this
      mechanism is identical to the PIN authenticated scheme except that
      the PIN code is presented to the connecting device by means of a
      QR code.

   Preconfigured (Static QR Code Authenticated)  For connecting devices
      that have been preconfigured with a device profile identified by
      means of a QR Code containing an EARL.  The QR code is scanned by
      the administration device after which both devices can complete
      the interaction.

   Each of these interactions provide strong mutual authentication with
   minimal user effort.

   The witness authenticated connection interaction is intended for use
   in cases in which the device is already connected to a network.  The
   QR code interactions are intended to provide support for acquisition
   of networking capabilities as part of the connection process.  These
   functions are not currently specified.  The Static QR Code
   Authenticated interaction is intended to support Internet of Things
   (IoT) devices which provide minimal interaction affordances.

   In each case, the objectives of the device connection interaction are
   the same:

   *  Mutually authenticate the onboarding device and the Mesh such that
      the connection interaction only completes if both sides acquire
      the authentic profile of the other.

   *  To provision the onboarding device with the Mesh ProfileAccount,
      and an ActivationDevice and ConnectionDevice record allowing the
      device to interact as a member of the Mesh with the set of rights
      specified by the user.

   *  To create a CataloguedDevice record and append it to the Device
      catalog of the account to allow the device to be managed within
      that account.

   *  (optional) to acquire networking capabilities to allow the above
      to be completed.

   The connection of the device to the Mesh Account is achieved through
   the creation of the ActivationDevice, ConnectionDevice and
   CataloguedDevice records described in
   [draft-hallambaker-mesh-schema].  These are created by the

   administration device in the third phase of each of the connection
   interactions described below and acquired by the onboarding device in
   the fourth phase.

9.1.  Witness/PIN Authenticated

   The witness authenticated, PIN authenticated, and Dynamic QR code
   interactions all follow a common interaction pattern.

   The Dynamic QR Code (PIN) Authenticated interaction comprises four
   phases as follows:

   Phase 1: Issue of PIN credential (PIN and Dynamic QR code only)  A
      PIN code is created and registered with the PIN Registration
      interaction described earlier and transmitted to the user by an
      out of band communication.  In the case of the Dynamic QR code
      interaction, this is a QR code that is scanned by the connecting
      device.

   Phase 2: Onboarding Device Request to Service  The onboarding device
      creates a RequestConnect message.  In the PIN authenticated and
      Dynamic QR Code interactions, the RequestConnect is authenticated
      by the Device Authentication key and the PIN issued earlier.  In
      the Witness Authenticated interaction, it is authenticated by the
      Device Authentication key alone.

      The onboarding device presents the RequestConnect message to the
      service by means of a Connect operation to the service servicing
      the account.  This results in the exchange of the account and
      device profiles and the computation of a witness value from the
      two profile fingerprints and two nonce values specified by the
      onboarding device and the service.  An AcknowledgeConnection
      message is posted to the Inbound spool of the account and returned
      to the connecting device.

   Phase 3: Administration Device Acceptance  The account holder
      authenticates RequestConnect message and uses an administrative
      device to accept or reject the connection request.

      If the RequestConnect message has been authenticated by a PIN
      code, the connection request can be accepted automatically without
      additional user interaction.

   Phase 4: Onboarding Device Completion  The onboarding device
      periodically polls the service for acceptance of the request by
      the administration device using the Complete transaction.

   The use of the PIN code to authenticate the request message is shown
   in $$$$.

   The PIN code MAY be presented to the onboarding device in any format
   accepted by the device.  Administration MAY support presentation of
   the account address PIN code as a URI code.  Administration devices
   SHOULD support presentation of the account address PIN code as a QR
   code containing the corresponding URI.

9.1.1.  Phase 1:

   Alice> meshman account pin /threshold
   PIN=AAIT-WXRD-BVB7-3BBT-D6JS-44GE-B4
    (Expires=2022-10-19T12:48:11Z)

   The registration of this PIN value was shown earlier in section $$$

   The URI containing the account address and PIN is:

   mcu://alice@example.com/AAIT-WXRD-BVB7-3BBT-D6JS-44GE-B4

9.1.2.  Phase 2:

   The onboarding device scans the QR code to obtain the account address
   and PIN code.  The PIN code is used to authenticate a connection
   request:

   Alice3> meshman device request alice@example.com /pin ^
       AAIT-WXRD-BVB7-3BBT-D6JS-44GE-B4
      Device UDF = MDVU-AOST-TDIH-AXGE-WUJS-I56V-WJP3
      Witness value = AI7W-YKPK-MR3U-CZW7-GAVQ-24LZ-MSFA

   The device generates a RequestConnect message as follows:

   {
     "RequestConnection":{
       "AccountAddress":"alice@example.com",

   The service receives the conenct request and authenticates the
   message under the device key.  The service cannot authenticate the
   message under the PIN code because that is not know to the service as
   the service cannot decrypt the local spool.

   Having authenticated the connect request, the service generates a
   random nonce value.  The random nonce together with the device and
   account profiles are used to calculate the witness value.

   The AcknowledgeConnection message is created by the service:

   The AcknowledgeConnection message is appended to the Inbound spool of
   the account to which connection was requested so that the user can
   approve the request.  The ConnectResponse message is returned to the
   device containing the AcknowledgeConnection message and the profile
   of the account.

   The device generates the witness value, verifies it against the value
   provided by the server and presents it to the user as seen in the
   console example above.

   The user synchronizes their pending messages:

   The administration device determines that the device connection
   request is authenticated by a PIN code.  The PIN code is retrieved
   and the message authenticated.  This is shown in the PIN registration
   interation example in section $$$ above.

   Bug: This command is currently showing superflous pending messages
   due to the failure to clear messages processed in earlier examples.

   The Cataloged device record is created from the public key values
   corresponding to the combination of the public keys in the device
   profile and those defined by the activation.

   This is returned to the onboarding device by wrapping it in a
   RespondConnection message posted to the local spool of the account.

9.1.4.  Phase 4

   The device periodically polls for completion of the connection
   request using the Complete transaction.

   To provide a final check on the process, the command line tool
   presents the UDF of the account profile to which the device has
   connected if successful:

   Alice3> meshman device complete
      Device UDF = MDVU-AOST-TDIH-AXGE-WUJS-I56V-WJP3
      Account = alice@example.com
      Account UDF = MDRR-5W72-3RJO-VZB3-VUVQ-IOEC-6UNA
   Alice3> meshman account sync

   The completion request specifies the witness value for the
   transaction whose completion is being queried:

   {
     "CompleteRequest":{
       "AccountAddress":"alice@example.com",
       "ResponseID":"MBI3-QJW4-3BIO-7SBZ-PEJP-E7NX-3W7E"}}

   The Service responds to the complete request by checking to see if an
   entry has been added to the local spool.  If so, this contains the
   RespondConnection message created by the administration device.

9.2.  Preconfigured (Static QR Code)

   The preconfigured device connection interaction is used to connect
   devices that lack affordances such as a display or a keyboard.  It is
   also known as the static QR code interaction because a static QR code
   printed on the device itself is used to connect it to a user's
   account.

   *Future*: Note that this interaction is likely to be changed
   substantially in future revisions of the specification and the Claim/
   PollClaim mechanism removed and replaced with a messaging based
   approach.

Internet-Draft           Mesh Protocol Reference            October 2022


   The interaction has five phases:

   Phase 1: Preconfiguration  The device to be onboarded is
      preconfigured with a ProfileDevice and private key information and
      a DeviceDescription posted to a publication service.  This process
      is typically performed during manufacture.  An EARL providing the
      ability to locate and decrypt the description is printed on the
      device itself as a QR code.

   Phase 2: Device description acquisition  The administration device
      acquiring the onboarding device scans the QR code on the device
      and uses this information to obtain the device description by
      means of a Claim operation described above as described in the
      Device Description.

   Phase 3: Administration Device Acceptance  This phase is performed in
      the same manner as the Dynamic QR Code (PIN) Authenticated
      interaction except that the administration device MAY advise the
      device that a connection request is being made by additional means
      described in the device description (e.g.  WiFi, Bluetooth).

   Phase 4: Poll Claim Notification  When connected to a network, the
      preconfigured device periodically attempts to poll the connection
      sources specified to find out if there is a pending request.  If a
      connection request is posted, the device decrypts it to allow it
      to complete the connection process.

   Phase 5: Onboarding Device Completion  This phase is performed in the
      same manner as the Dynamic QR Code (PIN) Authenticated interaction
      except that the administration device requires notice that of the
      pending connection request.

   The main differences between this connection interaction and the
   witness/PIN connection interactions are that the device is
   preconfigured with the device profile at the time of manufacture and
   the onboarding device MAY be acquiring network configuration
   information during the connection process.

9.2.1.  Phase 1

   This results in the creation of a primary secret which is used to
   compute a ProfileDevice and corresponding connection records signed
   by the manufacturer's administrator key.

   The data is combined to create a DevicePreconfiguration record that
   is provisioned to the firmware of the device being preconfigured.

   An EARL is created specifying the means by which an administration
   device can acquire the information required to complete a connection
   to the device:

   QR = {Connect.ConnectEARL}

   The preconfigured ProfileDevice is encrypted under the encryption key
   and published to the location key derived from the EARL.

9.2.2.  Phase 2 & 3

   The administration device scans the QR code and obtains the Device
   Description using the Claim operation as shown in section $$$$. The
   administration device creates the ActivationDevice and
   CatalogedDevice records and populates the service as before.

9.2.4.  Phase 5

   Having been advised that an account has published a claim to bind to
   it, the device posts a connection Complete request to the specified
   account and completes the connection process as before.

10.  Protocol Schema

   HTTP Well Known Service Prefix: /.well-known/mmm

   Every Mesh Portal Service transaction consists of exactly one request
   followed by exactly one response.  Mesh Service transactions MAY
   cause modification of the data stored in the Mesh Service or the Mesh
   itself but do not cause changes to the connection state.  The
   protocol itself is thus idempotent.  There is no set sequence in
   which operations are required to be performed.  It is not necessary
   to perform a Hello transaction prior to any other transaction.

10.1.  Request Messages

   A Mesh Portal Service request consists of a payload object that
   inherits from the MeshRequest class.  When using the HTTP binding,
   the request MUST specify the portal DNS address in the HTTP Host
   field.

10.1.1.  Message: MeshRequest

   Base class for all request messages.

   [No fields]

10.1.2.  Message: MeshRequestUser

   Base class for all request messages made by a user.

   Inherits: MeshRequest

   Account: String (Optional)  The fully qualified account name
      (including DNS address) to which the request is directed.

   Capability: String (Optional)  The identifier of the capability under
      which access is claimed.

   EnvelopedProfileDevice: Enveloped (Optional)  Device profile of the
      device making the request.

Internet-Draft           Mesh Protocol Reference            October 2022


10.2.  Response Messages

   A Mesh Portal Service response consists of a payload object that
   inherits from the MeshResponse class.  When using the HTTP binding,
   the response SHOULD report the Status response code in the HTTP
   response message.  However the response code returned in the payload
   object MUST always be considered authoritative.

10.2.1.  Message: MeshResponse

   Base class for all response messages.  Contains only the status code
   and status description fields.

   [No fields]

10.3.  Imported Objects

   The Mesh Service protocol makes use of JSON objects defined in the
   JOSE Signatgure and Encryption specifications and in the DARE Data At
   Rest Encryption extensions to JOSE.

10.4.  Common Structures

   The following common structures are used in the protocol messages:

10.4.1.  Structure: KeyValue

   Describes a Key/Value structure used to make queries for records
   matching one or more selection criteria.

   Key: String (Optional)  The data retrieval key.

   Value: String (Optional)  The data value to match.

10.4.2.  Structure: ConstraintsSelect
