Agenda for CFRG at interim-2014-cfrg-1
agenda-interim-2014-cfrg-1-1

Hi CFRG,

the interim will take place on Tuesday, April 29 at 3PM ET, and will be
around two and one-half hours in length.  It will be a purely virtual
teleconference hosted as a Webex Meeting; there is no physical meeting
place.  Slides will be distributed in advance, and it will be possible
to follow along on audio by calling a toll free number.   Discussion
will be moderated, as is needed for any large teleconference.   To
participate, see the instructions at the end of this email.

Agenda:

3:00  David McGrew: Current ECC standards and problem statement.  15
minutes.
3:15  Rene Struik: Fixing the EC-DRBG.  20 minutes.
3:35  Dan Brown: Random curves: security benefits, generation methods,
and Cheon attacks.  10 minutes.
3:45  Watson Ladd: On the security of twisted Edwards Curves.  20
minutes.
4:05  Patrick Longa: Selecting Elliptic Curves for Cryptography.   45
minutes.
4:50  Discussion
  1) What curves and algorithms are safe to use on the Internet?
  2) What curves and algorithms are desirable to use in Internet
protocols, considering criteria beyond just security, such
implementation costs and interoperability?

Rene, Dan, Watson, and Patrick, please send out your slides to
cfrg@irtf.org before the meeting starts.   Thank you for volunteering
your time to prepare and present to the group.

Here are some background materials, including the minutes that led to
the planning of this meeting, and some references suggested by
participants.
