                  The Requirements for Secure Routing
               draft-chen-secure-routing-requirements-01

Abstract

   Both ISPs and users have put forward requirements for secure routing,
   the scenarios are analyzed in the draft draft-chen-secure-routing-
   use-cases.  This draft analyzes the functions required to implement
   secure routing.

   Attack detection and users security requirements translateion are out
   of scope.

1.  Introduction

   Starting from the requirements of network operators and users, it is
   necessary to take the security attribute as the key factor to select
   the route and transmission path to measure the link transmission
   security.  To achieve this goal, the following contents need to be
   studied.

   1.  Static node security, by appraising the trustworthiness;

   2.  Expression of node security capability, by YANG Model;

   3.  Type of security functions: reorganize and define the security
       functions supported by existing network devices, and encode them,
       such as security monitoring, traffic filtering.  Generally, the
       security functions of a device can be described as a collection.

   4.  Protocol for collecting node security capabilities, such as
       adding new parameters to BGP-LS;

   5.  A protocol for distributing security policy configuration, by
       SRv6;

2.  Requirements for Secure Routing

2.1.  Appraise trustworthiness

   TBD

2.2.  Expression of security capability

   YANG model is used to describe the security capability of nodes, such
   as security service type and remaining capacity.

2.3.  Type of security functions

   Fine-grained security functions, more detail in draft draft-chen-
   atomized-security-functions.

2.4.  Node security capability collection protocol

   Collect the security capabilities of all nodes in the network through
   BGP-LS, more detail in draft draft-chen-idr-bgp-ls-security-
   capability.

2.5.  Distribution of security policy

   Security policies can be distributed through extended SRv6 SRH.

3.  IANA Considerations

   This memo includes no request to IANA.

4.  Security Considerations

   TBD
