The IESG has approved the following document: - 'Using Counter Modes with Encapsulating Security Payload (ESP) and Authentication Header (AH) to Protect Group Traffic' <draft-ietf-msec-ipsec-group-counter-modes-06.txt> as a Proposed Standard This document is the product of the Multicast Security Working Group. The IESG contact persons are Tim Polk and Sean Turner. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-msec-ipsec-group-counter-modes/ Technical Summary Counter modes have been defined for block ciphers such as the Advanced Encryption Standard (AES). Counter modes use a counter, which is typically assumed to be incremented by a single sender. This memo describes the use of counter modes when applied to the Encapsulating Security Payload (ESP) and Authentication Header (AH) in multiple-sender group applications. Working Group Summary One of the main comments received (Alfred Hoenes) concerns the need to make the proposal compatible with any AES-like block ciphers (it was previously restricted to AES). It has been addressed. There was no controversial issue. Document Quality The document is small and easy to read. I am not aware of the existence of an implementation but it's likely one will be done, if not already the case. Personnel Vincent Roca is the shepherd. Tim Polk is the responsible Area Director. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
