Biography

Charles Rackoff was born and raised in New York City. He attended MIT as both an undergraduate and graduate student, receiving a PhD in Computer Science in 1974. After spending a year as a post-doc at INRIA in France, he joined the University of Toronto Computer Science Dept. in 1974. His research interests are in computational complexity. For some time now he has been specializing in Cryptography, Security, and Security protocols. He was a co-originator of the important concepts of "interactive proofs" and "zero-knowledge proofs", for which he co-won the 1993 Godel Prize.

CITO Project

Professor Rackoff is the head of the CITO project entitled Fundamental Issues in Computing.
