Workshop on the Elliptic Curve Discrete Logarithm Problem

University of Waterloo, Waterloo, Ontario, Canada
November 3 & 4, 1997

The primary basis for the security of elliptic curve cryptosystems is the intractability of the elliptic curve discrete logarithm problem (ECDLP). The aim of this workshop is to bring together researchers who are interested in the ECDLP and related topics. It is hoped that the meeting will encourage and stimulate further research on the ECDLP, and more generally on the security of elliptic curve cryptosystems.

There will be 10 one-hour invited lectures (and no contributed talks), with the remaining time used for informal discussions
