Abstract

We describe the Diffie-Hellman key-exchange protocol and the Pohlig-Hellman cipher. We discuss discrete logarithms and the cryptanalysis of these two systems. We also describe the Mental Poker protocol.

His research interests are in the areas of cryptography, parallel computation, and analysis of algorithms, especially number theoretic algorithms. He and J. W. Smith of the University of Georgia have built a special processor with parallel capability for factoring large integers.
