          Integrity Check Value and Timestamp TLV Definitions
                  for Mobile Ad Hoc Networks (MANETs)

Abstract

   This document 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.
