DEPARTMENT OF MATHEMATICS, UNIVERSITY OF CALIFORNIA, BERKELEY SPRING 2002 COLLOQUIUM Speaker: Dan Boneh (Stanford University) Title: Fast variants of the RSA cryptosystem Time: February 28, 2002, 4:10 - 5:00 pm Place: 60 Evans Hall (ground floor) Abstract: The RSA system is the most widely deployed public key cryptosystem. In this talk we survey four fast variants of RSA that are fully backwards compatible - a system using any of these variants can interact with a system using standard RSA. The design and cryptanalysis of these RSA variants is based on a number of algebraic techniques. The talk will be self-contained and describe some of the necessary algebraic tools. Refreshments in 1015 Evans Hall (tenth floor) before the lecture. EVERYBODY IS WELCOME TO ATTEND! After the lecture there will be a Colloquium Dinner. If you are interested in attending, write to the Colloquium Chair no later than Wednesday afternoon. Graduate students are particularly encouraged to attend; they pay at most $ 15 per person.
