RE: I-D ACTION:draft-ietf-sip-smime-aes-00.txt

I'm glad that the draft is some of interest to this WG, since we could
probably use some advice from the S/MIME experts on our direction.

This document proposes to profile S/MIME for SIP, specifically by exchanging
the mandatory Triple-DES encryption algorithm requirement for AES. Some of
the reasons why AES would be a better fit for SIP are given in the draft.
There is, however, some concern that this might lead to non-interoperability
with standard S/MIME stacks, and so on.

I see that rfc2633bis 2.7 makes Triple-DES mandatory. Is it likely that
S/MIME down the road will require AES? Does the proposal in this draft seem
like a wrong-headed profile to this WG?

RFC3261 currently specifies 3DES as the required minimum ciphersuite
for implementations of S/MIME in SIP.  This document updates the
normative guidance of RFC3261 to require the Advanced Encryption
Standard (AES) for S/MIME.
