Elliptic Curve Cryptography (ECC) Brainpool Curves for Transport Layer Security (TLS)
draft-merkle-tls-brainpool-04

[Ballot comment]

Sigh... More knobs to turn for TLS. Personally I really
hope TLS1.3 dramatically cuts down this ciphersuite
parameter explosion, but in the meantime this is only
making the status quo very marginally worse and the
specific ciphers seem ok.

For the authors: that's not actionable, and not a dig at
you, but more at how we (the IETF as a whole) have allowed
this situation to develop over the last decade. I do
understand that your use-case is as real as many others.

Nit: I'd suggest using BSI on the title page for Manfred's
affiliation.

Subject: Last Call:  (ECC Brainpool Curves for Transport Layer Security (TLS)) to Informational RFC


The IESG has received a request from an individual submitter to consider
the following document:
- 'ECC Brainpool Curves for Transport Layer Security (TLS)'
  as Informational RFC

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf@ietf.org mailing lists by 2013-07-23. Exceptionally, comments may be
sent to iesg@ietf.org instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.

Abstract


  This document specifies the use of several ECC Brainpool curves for
  authentication and key exchange in the Transport Layer Security (TLS)
  protocol.
