          Integrity Check Value and Timestamp TLV Definitions
                  for Mobile Ad Hoc Networks (MANETs)
                    draft-ietf-manet-rfc6622-bis-01

Abstract

   This document extends and replaces RFC 6622.  It describes general
   and flexible TLVs for representing cryptographic Integrity Check
   Values (ICVs) (i.e., digital signatures or Message Authentication
   Codes (MACs)) as well as 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 an
   address, respectively.
