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.

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.

Is there any technical difference between 19 and 189 other then a slight
change in square root calculations?
