                KARP KMP: Simplified Peer Authentication
             draft-chunduri-karp-kmp-router-fingerprints-01

Abstract

   This document describes the usage of Router Fingerprint
   Authentication (RFA) with public keys as a potential peer
   authentication method with KARP Key Management Protocol (KMP).  The
   advantage of RFA is, neither it requires out-of-band, mutually
   agreeable symmetric keys nor a full PKI based system (trust anchor or
   CA certificates) for mutual authentication of the peers with KARP KMP
   deployments.  Usage of Router Fingerprints give a significant
   operational improvement from symmetric key based systems and yet
   provide a secure authentication technique.

Internet-Draft  KARP KMP: Simplified Peer Authentication    October 2012

1.  Introduction

   A Key Management Protocol (KMP) framework for TCP-based pair wise
   routing protocols (BGP [RFC4271], PCEP [RFC5440], MSDP [RFC3618] and
   LDP [RFC5036]) is detailed in
   [chunduri-karp-using-ikev2-with-tcp-ao].  Usage of IKEv2[RFC5996] as
   the KMP is also described in the same document.  This draft explores
   a simple and secure authentication method, which can be used for KARP
   KMP deployments.

   Currently operators don't often change the manual keys deployed for
   protecting the Routing Protocol (RP) messages because of various
   reasons as noted in Section 2.3 of KARP threat document [I-D.ietf-
   karp-threats-reqs].  One of the KARP WG goals is to define mechanisms
   to support key changes for all RPs which use either Manual Key
   Management (MKM) or KMP with out much operational overhead.

   Apart from Peer's identity verification, authentication and parameter
   negotiation, deployment of KMP can be more useful, when it comes to
