1997 Fall Nagle Lecture

Arjen Lenstra
Securing the Net: the Fruits of Incompetence
October 23, 1997

Description of the Talk

Only a fraction of Internet security breaches are publicized. In this talk I will show how elementary mathematical tools should improve network security and how their effectiveness is mostly based on our incompetence.

Description of the Speaker

After Arjen K. Lenstra got his Ph.D. from the University of Amsterdam, he was a visiting professor at the University of Chicago, while consulting for IBM, AT&T Bell Labs, and DEC SRC. In 1989, he joined the Mathematics and Cryptography research group at Bellcore, and later moved to the Corporate Technology Office of Citibank.

His major research interest is Computational Number Theory, in particular algorithms for factoring integers and computing discrete logarithms. He developed a portable toolkit for experimenting with cryptographic protocols; this software was used in 1994 to break the famous 1977 RSA-Challenge number. He is one of the co-developers of the recent number field sieve factoring algorithm.
