          Integrity Check Value and Timestamp TLV Definitions
                  for Mobile Ad Hoc Networks (MANETs)
                    draft-ietf-manet-rfc6622-bis-03

Abstract

   This document revises, extends and replaces RFC 6622.  It describes
   general and flexible TLVs for representing cryptographic Integrity
   Check Values (ICVs) and timestamps, using the generalized Mobile Ad
   Hoc Network (MANET) packet/message format defined in RFC 5444.  It
   defines two Packet TLVs, two Message TLVs, and two Address Block TLVs
   for affixing ICVs and timestamps to a packet, a message, and one or
   more addresses, respectively.
