The IESG has approved the Internet-Draft 'The AES Cipher Algorithm
and Its Use With IPsec' <draft-ietf-ipsec-ciph-aes-cbc-04.txt> as a
Proposed Standard. This document is the product of the IP Security
Working Group (IPSEC).
The IESG contact persons are Russ Housley and Steven Bellovin.
Technical Summary
Since IPsec was first developed, the U.S. National Institute of
Standards and Technology (NIST) has completed a process for selecting
the new Advanced Encryption Standard (AES). AES uses longer keys
than the original Data Encryption Standard (DES) that is used by IPsec
for confidentiality. AES also uses a larger encryption block size.
This document describes the use of the AES Cipher Algorithm in Cipher
Block Chaining (CBC) mode as a confidentiality mechanism within the
context of the IPsec Encapsulating Security Payload (ESP) protocol.
Working Group Summary
The Working Group came to consensus on this document.
Protocol Quality
This document was reviewed by Jeffrey I. Schiller for the IESG.
