Fields Cryptography Retrospective Meeting
May 11-15, 2009

to be held at
Fields Institute, 222 College Street, Toronto

Supported by

Organizing Committee
John Friedlander, University of Toronto
Kristin Lauter, Microsoft Research

Igor Shparlinski, Macquarie University
Hugh Williams, University of Calgary
This is a follow-up workshop which is related to and built on the success of the Thematic Program on Cryptography which was held at the Fields institute in 2006. Its purpose is to survey the foremost achievements in the area (partially inspired by the success of the Thematic Program) and also to outline new directions for further investigation.


This program will engage the cryptographic and mathematical communities in Canada and abroad to increase awareness of recent developments in these fields and to initiate a greater degree of collaboration in attacking the important problems, particularly on the boundaries. Developments in certain areas of mathematics (for example, number theory, combinatorics, algebraic geometry) and in cryptography are both numerous and rapid; however, it is often the case that lack of contacts and communication between cryptographers and mathematicians presents obstacles in achieving significant advances on both sides. We hope to overcome these obstacles and foster new links between both areas.

The specific areas of concentration will be:

  • algebraic curves and cryptography
  • computational challenges arising in algorithmic number theory and cryptography
  • group theory based cryptography
  • new cryptographic protocols

It is planned to have to a series of invited talks surveying recent advances in the above areas and several contributed talks by some participants describing their most recent results.
