   Title:   Additional Cryptographic Algorithms For Use With TCP-AO

Abstract:

   RFC5926 creates a list of cryptographic algorithms that can be used
   with TCP-AO.  This document expands that list, adding two Message
   Authentication Code (MAC) algorithms, HMAC-SHA256-128 and
   KMAC256-128.  For each MAC algorithm, a corresponding Key Derivation
   Function (KDF) is also added.

   The MAC algorithms described by this document produce 128-bit (i.e.,
   16-byte) MACs.  When 16-byte MACs are encoded in TCP-AO, the TCP-AO
   consumes 20 bytes.  This does not challenge TCP's 40-byte option size
   limitation.
