[TLS] AUTH48, RFC 4492 <draft-ietf-tls-ecc-12.txt> NOW AVAILABLE

[Vipul Gupta <[e-mail]>]

We are in the AUTH48 stage with draft-ietf-tls-ecc-12.txt.
The pre-release version of the RFC 4492 is currently available
at:

ftp://ftp.rfc-editor.org/in-notes/authors/rfc4492.txt

The coauthors would like to update the table in
Appendix A in response to a new release of X9.62. The
suggested change is in the attached email -- it adds a new column
for X9.62-2005 and lists aliases that spec defines for
18 of the 25 curves in the draft. This change has no material
impact on the specification and is purely informative --
intended to help implementers sort out different names
used by NIST, ANSI and SECG for the same curves.

If there are good reasons to not include this change, please
let us know as soon as possible. We'd like to come to a final
decision (either include or leave out the new column) later
this week.

thank you,

vipul
