Room 124, H. R. Bright Building


Twenty years of cryptography and codes


Dr. George R. Blakley

G. R. Blakley is a former mathematics department head who works in information science, particular its cryptographic aspects. He and Adi Shamir invented secret sharing in 1979. He has taught at Maryland, Illinois and Buffalo, and has done postdoctoral work at Harvard and Cornell. He has served on the board of directors of the International Association for Cryptologic Research, and has had research support from many federal agencies supporting science.


Recent developments in cryptography have led to a general theory of codes. It provides a unified treatment of cryptographic topics such as secure log-in, cryptosystem codes, key exchange schemes and secret sharing schemes.

It also treats topics from outside cryptography, such as error control codes, data compression codes, quantum codes, and genetic codes.

The talk will review some highlights of cryptography since 1975, with emphasis on the great expansion in the variety of codes cryptographers have invented over that period.


Everyone is invited and welcome to attend the seminars in this series.
