If I recall correctly what an implementor once told me, the work
involved in taking the fields that are immutable, then hashing
packet, then sticking those immutable fields back in is actually more
work than encrypting. Surprised me at the time but seems to be the
case.

Hi,
Interesting discussion on the utility of Authentication Header (AH) in
IPSecME WG.
http://www.ietf.org/mail-archive/web/ipsec/current/msg05026.html
Post explaining that AH even though protecting the source and
destination IP addresses is really not good enough.
http://www.ietf.org/mail-archive/web/ipsec/current/msg05056.html
What do folks feel? Do they see themselves using AH in the future?
IMO, ESP and WESP are good enough and we dont need to support AH any
more ..
