Using Counter Modes with Encapsulating Security Payload (ESP) and Authentication Header (AH) to Protect Group Traffic
draft-ietf-msec-ipsec-group-counter-modes-06
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.
