Dear Alfred, and all

Many thanks for your review. A new version has been submitted yesterday,
it incorporated the proposed textual improvements (The new version is
available at
http://www.ietf.org/internet-drafts/draft-ietf-tls-psk-new-mac-aes-gcm-03.txt),
and your proposal on the new cipher suites as well.

I hope the WG chairs can proceed to a WGLC.

Best regards,
Badra

Folks,
I have once more studied the new version of the draft,
   draft-ietf-tls-psk-new-mac-aes-gcm-02,
and reported off-list a bunch of editorial nits, and proposals
for small textual improvements in the Abstract and Introduction.
I guess the list is not interested in the details, only in the
outcome.

I only had a single technical point:

 There's an imbalance in the portfolio regarding cipher suites
 with NULL encryption -- cf. Sections 3.1 & 3.2 vs. Section 3.3.

 Because RFC 4785 did not make a distinction in the SHA-1 case,
 I have proposed to add to Section 3.3 (and Section 5) the
 'missing' corresponding cipher suite definitions for SHA-2,
 TLS_RSA_PSK_WITH_NULL_SHA{256|384}.

Any objections?

Otherwise, I see no open issues, and support entering WGLC
as soon as the suggested improvements have been considered.
The above question IMO might be left open for WGLC discussion.

Best regards,
 Alfred.
