Protocol Action: 'Using AES Counter Mode With IPsec ESP' to Proposed Standard
The IESG has approved the Internet-Draft 'Using AES Counter Mode With IPsec
ESP' <draft-ietf-ipsec-ciph-aes-ctr-05.txt> as a Proposed Standard. This
document is the product of the IP Security Protocol Working Group. The IESG
contact persons are Steve Bellovin and Russ Housley
Technical Summary
This is a new cipher description for IPsec. In particular, it describes how to
use AES in counter mode within the ESP framework. Counter mode is especially
useful for very high speed implementations, since it can be parallelized very
easily. Counter mode is easily misused; however, this draft contains adequate
warnings, cautions, and requirements to prevent such misue.
Working Group Summary
There was strong working group consensus to advance this document and it has a
significant pull from the community, including groups that need high-speed IPsec.
Protocol Quality
This document was reviewed for the IESG by Steve Bellovin.
