Protocol Action: The AES Cipher Algorithm and Its Use With IPsec

  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).

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.
