Gentle people,
I can find no patent disclosures on this document listed on the IETF
IPR
search page at https://datatracker.ietf.org/ipr/search/ using
draft-ietf-tls-ecc-new-mac as the I-D Filename.
Elliptic curve cryptography is a heavilly patented area, and it seems
impossible that this draft does not involve an existing patent.
I also seemed to have missed the discussion of non-patented
alternatives, as required by RFC3979.
Surely the IESG would not approve a document AGAIN that did not
disclose
its patent status in violation of RFC3979 et al!?!
I have to object to the approval of this draft on those grounds. I am
very concerned that the IESG would not be more circumspect and careful
in light of the previous TLS-Authz scandal. See
http://www.av8.net/IETF-watch/People/Housley/index.html
http://www.av8.net/IETF-watch/People/TimPolk/index.html
for more information about TLS-Authz.

Technical Summary
This document describes new ECC cipher suites for TLS which
specify stronger MAC algorithms. Eight use HMAC with SHA-256 or
SHA-384 and eight use AES in Galois Counter Mode (GCM).
Working Group Summary
This document is a product of the Transport Layer Security (TLS)
Working Group. The document represents the consensus of the TLS
working group.
Document Quality
There has been significant review of the document by members of
the TLS working group on the document and changes were made to
improve the document based on these reviews.
Personnel
The Document Shepherd for this document is Joseph Salowey, and the
responsible Area Director is Pasi Eronen.
RFC Editor Note
In document title, expand "GCM" to "Galois Counter Mode (GCM)"
Abstract:
OLD:
However, all those cipher suites use SHA-1 as their MAC
algorithm. This document describes sixteen new cipher suites
for TLS which specify stronger digest algorithms.
NEW:
However, all those cipher suites use HMAC-SHA1 as their MAC
algorithm. This document describes sixteen new cipher suites
for TLS which specify stronger MAC algorithms.
Section 3.1
OLD:
These eight cipher suites are the same as the corresponding
cipher suites in RFC 4492 (with names ending in "_SHA" in place
of "_SHA256" or "_SHA384"), except for the hash and PRF
algorithms.
NEW:
These eight cipher suites are the same as the corresponding
cipher suites in RFC 4492 (with names ending in "_SHA" in place
of "_SHA256" or "_SHA384"), except for the MAC and PRF
algorithms.
