Rackoff studied at the Massachusetts Institute of Technology, where he was in 1974 da Silva Meyer PhD at Albert Ronald (The Computational Complexity of Logical Theories Handsome ). As a post-doc he was in Paris at the INRIA. He is a professor at the University of Toronto, where he has been since 1974.
Rackoff dealt with complexity theory. With Silvio Micali and Shafi Goldwasser he led a 1982 Interactive proof systems and zero- knowledge proofs, for which the three 1993 first Gödel Prize received.
