      Integrity Protection for Control Messages in NHDP and OLSRv2
                  draft-ietf-manet-nhdp-olsrv2-sec-01

Abstract

   This document specifies integrity and replay protection for required
   implementation in the MANET Neighborhood Discovery Protocol (NHDP)
   and the Optimized Link State Routing Protocol version 2 (OLSRv2).
   This document specifies how an included integrity check value (ICV)
   and a timestamp TLV, defined in RFC6622bis, are used by NHDP and
   OLSRv2 for countering a number of security threats.  The ICV TLV uses
   a SHA-256 based HMAC and one or more shared secret keys.  The
   timestamp TLV is based on POSIX time, and assumes that the clocks in
   all routers in the network can be synchronized with sufficient
   precision.  The mechanism in this specification can also be used for
   other MANET protocols using RFC5444.
