Subject: Protocol Action: The AES-XCBC-MAC-96 Algorithm and Its Use
With IPsec to Proposed Standard
-------------
The IESG has approved "The AES-XCBC-MAC-96 Algorithm and Its Use With
IPsec" <draft-ietf-ipsec-ciph-aes-xcbc-mac-02.txt> as a Proposed
Standard.
The IESG contact persons are Steve Bellovin and Jeff Schiller
Technical Summary
This document defines a new hash algorithm for use in IPsec ESP. It
is a variant of the traditional use of a cipher in Cipher Block
Chaining (CBC) Mode to compute a hash value. However traditional CBC
mode hashes are vulnerable to attack if the amount of data to be
protected is of variable length. This document defines a variant of
this approach, applied to the Advanced Encryption Standard (AES)
that is proof against this vulnerability.
