[Cfrg] FW: New Version Notification for draft-black-numscurves-00.txt

[Brian LaMacchia <[e-mail]>]

Dear CFRG members,

I would like to draw your attention to the Internet-Draft draft-black-numscurves-00.txt, https://datatracker.ietf.org/doc/draft-black-numscurves/, which has just been submitted by Ben Black and the co-authors of [1].  This I-D contains the specification for the NUMS curves that Patrick Longa presented at the CFRG Spring 2014 Interim Meeting and which are implemented in the just-released Microsoft Research ECCLib  (see my message at http://www.ietf.org/mail-archive/web/cfrg/current/msg04602.html for that announcement).   For the reasons described both in the paper and the presentation at the Interim Meeting, I believe that it would be best for the CFRG to standardize a family of both Weierstrass and twisted Edwards curves generated through publicly verifiable means in order to meet the broad needs of the IETF.  

With the submission of this I-D and the release of MSR's open source implementation, I believe the feedback received at the Interim Meeting concerning the proposed NUMS curves has been successfully addressed and I encourage the CFRG to have a more detailed and thoughtful discussion of the various curve candidates that have been proposed.   The needs of the entire IETF in this space, starting with the TLS WG, seem like a very ripe topic for discussion at IETF-90 in Toronto.

Abstract:
   This memo describes a family of deterministically generated Nothing
   Up My Sleeve (NUMS) elliptic curves over prime fields offering high
   practical security in cryptographic applications, including Transport
   Layer Security (TLS) and X.509 certificates.  The domain parameters
   are defined for both classical Weierstrass curves, for compatibility
   with existing applications, and modern twisted Edwards curves,
   allowing further efficiency improvements for a given security level.

                                                                                  


Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
