The National Institute of Standards and Technology (NIST) has recently
specified the Cipher-based Message Authentication Code (CMAC), which
is equivalent to the One-Key CBC-MAC1 (OMAC1) algorithm submitted by
Iwata and Kurosawa.  OMAC1 efficiently reduces the key size of
Extended Cipher Block Chaining mode (XCBC).  This memo specifies the
use of CMAC mode as an authentication mechanism of the IPsec
Encapsulating Security Payload (ESP) and the Authentication Header
(AH) protocols.  This new algorithm is named AES-CMAC-96.  

This is now a Proposed Standard Protocol.
