RFC 4101 Writing Protocol Models
 
Authors:E. Rescorla, IAB.
Date:June 2005
Formats:txt pdf
Status:INFORMATIONAL
The IETF process depends on peer review. However, IETF documents are generally written to be useful for implementors, not reviewers. In particular, while great care is generally taken to provide a complete description of the state machines and bits on the wire, this level of detail tends to get in the way of initial understanding. This document describes an approach for providing protocol "models" that allow reviewers to quickly grasp the essence of a system.

Authors:S. Bellovin, R. Housley.
Date:June 2005
Formats:txt pdf
Also:BCP 0107
Status:BEST CURRENT PRACTICE
The question often arises of whether a given security system requires some form of automated key management, or whether manual keying is sufficient. This memo provides guidelines for making such decisions.When symmetric cryptographic mechanisms are used in a protocol, the presumption is that automated key management is generally but not always needed. If manual keying is proposed, the burden of proving that automated key management is not required falls to the proposer.

RFC 4111 Security Framework for Provider-Provisioned Virtual Private Networks (PPVPNs)
 
Authors:L. Fang, Ed..
Date:July 2005
Formats:txt pdf
Status:INFORMATIONAL
This document addresses security aspects pertaining to Provider-Provisioned Virtual Private Networks (PPVPNs). First, it describes the security threats in the context of PPVPNs and defensive techniques to combat those threats. It considers security issues deriving both from malicious behavior of anyone and from negligent or incorrect behavior of the providers. It also describes how these security attacks should be detected and reported. It then discusses possible user requirements for security of a PPVPN service. These user requirements translate into corresponding provider requirements.In addition, the provider may have additional requirements to make its network infrastructure secure to a level that can meet the PPVPN customer's expectations. Finally, this document defines a template that may be used to describe and analyze the security characteristics of a specific PPVPN technology.

RFC 4135 Goals of Detecting Network Attachment in IPv6
 
Authors:JH. Choi, G. Daley.
Date:August 2005
Formats:txt pdf
Status:INFORMATIONAL
When a host establishes a new link-layer connection, it may or may not have a valid IP configuration for Internet connectivity. The host may check for link change (i.e., determine whether a link change has occurred), and then, based on the result, it can automatically decide whether its IP configuration is still valid. During link identity detection, the host may also collect necessary information to initiate a new IP configuration if the IP subnet has changed. In this memo, this procedure is called Detecting Network Attachment(DNA). DNA schemes should be precise, sufficiently fast, secure, and of limited signaling.

RFC 4137 State Machines for Extensible Authentication Protocol (EAP) Peer and Authenticator
 
Authors:J. Vollbrecht, P. Eronen, N. Petroni, Y. Ohba.
Date:August 2005
Formats:txt pdf
Status:INFORMATIONAL
This document describes a set of state machines for ExtensibleAuthentication Protocol (EAP) peer, EAP stand-alone authenticator(non-pass-through), EAP backend authenticator (for use onAuthentication, Authorization, and Accounting (AAA) servers), and EAP full authenticator (for both local and pass-through). This set of state machines shows how EAP can be implemented to support deployment in either a peer/authenticator or peer/authenticator/AAA Server environment. The peer and stand-alone authenticator machines are illustrative of how the EAP protocol defined in RFC 3748 may be implemented. The backend and full/pass-through authenticators illustrate how EAP/AAA protocol support defined in RFC 3579 may be implemented. Where there are differences, RFC 3748 and RFC 3579 are authoritative.

The state machines are based on the EAP "Switch" model. This model includes events and actions for the interaction between the EAPSwitch and EAP methods. A brief description of the EAP "Switch" model is given in the Introduction section.

The state machine and associated model are informative only.Implementations may achieve the same results using different methods.

 
RFC 4138 Forward RTO-Recovery (F-RTO): An Algorithm for Detecting Spurious Retransmission Timeouts with TCP and the Stream Control Transmission Protocol (SCTP)
 
Authors:P. Sarolahti, M. Kojo.
Date:August 2005
Formats:txt pdf
Updated by:RFC 5682
Status:EXPERIMENTAL
Spurious retransmission timeouts cause suboptimal TCP performance because they often result in unnecessary retransmission of the last window of data. This document describes the F-RTO detection algorithm for detecting spurious TCP retransmission timeouts. F-RTO is a TCP sender-only algorithm that does not require any TCP options to operate. After retransmitting the first unacknowledged segment triggered by a timeout, the F-RTO algorithm of the TCP sender monitors the incoming acknowledgments to determine whether the timeout was spurious. It then decides whether to send new segments or retransmit unacknowledged segments. The algorithm effectively helps to avoid additional unnecessary retransmissions and thereby improves TCP performance in the case of a spurious timeout. TheF-RTO algorithm can also be applied to the Stream ControlTransmission Protocol (SCTP).

RFC 4141 SMTP and MIME Extensions for Content Conversion
 
Authors:K. Toyoda, D. Crocker.
Date:November 2005
Formats:txt pdf
Status:PROPOSED STANDARD
A message originator sometimes sends content in a form the recipient cannot process or would prefer not to process a form of lower quality than is preferred. Such content needs to be converted to an acceptable form, with the same information or constrained information(e.g., changing from color to black and white). In a store-and- forward environment, it may be convenient to have this conversion performed by an intermediary. This specification integrates twoESMTP extensions and three MIME content header fields, which defines a cooperative service that permits authorized, accountable content form conversion by intermediaries.
 
RFC 4142 Full-mode Fax Profile for Internet Mail (FFPIM)
 
Authors:D. Crocker, G. Klyne.
Date:November 2005
Formats:txt pdf
Status:PROPOSED STANDARD
Classic facsimile document exchange represents both a set of technical specifications and a class of service. Previous work has replicated some of that service class as a profile within Internet mail. The current specification defines "full mode" carriage of facsimile data over the Internet, building upon that previous work and adding the remaining functionality necessary for achieving reliability and capability negotiation for Internet mail, on a par with classic T.30 facsimile. These additional features are designed to provide the highest level of interoperability with the standards-compliant email infrastructure and mail user agents, while providing a level of service that approximates what is currently enjoyed by fax users.

RFC 4151 The 'tag' URI Scheme
 
Authors:T. Kindberg, S. Hawke.
Date:October 2005
Formats:txt pdf
Status:INFORMATIONAL
This document describes the "tag" Uniform Resource Identifier (URI) scheme. Tag URIs (also known as "tags") are designed to be unique across space and time while being tractable to humans. They are distinct from most other URIs in that they have no authoritative resolution mechanism. A tag may be used purely as an entity identifier. Furthermore, using tags has some advantages over the common practice of using "http" URIs as identifiers for non-HTTP-accessible resources.

RFC 4185 National and Local Characters for DNS Top Level Domain (TLD) Names
 
Authors:J. Klensin.
Date:October 2005
Formats:txt pdf
Status:INFORMATIONAL
In the context of work on internationalizing the Domain Name System(DNS), there have been extensive discussions about "multilingual" or"internationalized" top level domain names (TLDs), especially for countries whose predominant language is not written in a Roman-based script. This document reviews some of the motivations for such domains, several suggestions that have been made to provide needed functionality, and the constraints that the DNS imposes. It then suggests an alternative, local translation, that may solve a superset of the problem while avoiding protocol changes, serious deployment delays, and other difficulties. The suggestion utilizes a localization technique in applications to permit any TLD to be accessed using the vocabulary and characters of any language. It is not restricted to language- or country-specific "multilingual" TLDs in the language(s) and script(s) of that country.

RFC 4189 Requirements for End-to-Middle Security for the Session Initiation Protocol (SIP)
 
Authors:K. Ono, S. Tachimoto.
Date:October 2005
Formats:txt pdf
Status:INFORMATIONAL
A Session Initiation Protocol (SIP) User Agent (UA) does not always trust all intermediaries in its request path to inspect its message bodies and/or headers contained in its message. The UA might want to protect the message bodies and/or headers from intermediaries, except those that provide services based on its content. This situation requires a mechanism called "end-to-middle security" to secure the information passed between the UA and intermediaries, which does not interfere with end-to-end security. This document defines a set of requirements for a mechanism to achieve end-to-middle security.
