Title: Department of Computer Science Seminar Date: Wednesday, Nov. 1, 2000 Time: 4:00 pm to 5:00 pm Venue: Room N101, CSIT Building [108] Speaker: Dr Giuseppe Jurman (Centre for Mathematics and its Applications, Australian National University) Description: "From Menet Khufu to quanta through Rijndael: a short trip into fubswrorjb" Abstract People's need to communicate secretly probably began with the discovery of writing: the earliest recorded example was carved over 4000 years ago in the tomb of an Egyptian nobleman. It is only in the last 300 years that the arts of encrypting document - cryptography - and decipher secret writings - cryptanalysis - have become more scientific. Now technology provides powerful tools to use the mathematical background more effectively. The talk will first show some of the classical private-key enciphering methods and then it will move on the more recent public-key algorithms, with a particular look at the mathematics involved. After a brief survey on the cryptanalytic side, the framework of the actual standard algorithms will be discussed and we will conclude with a quick glance towards the future.

I got my degree ("Laurea") in Mathematics at the University of Trento in 1993 with a thesis in Algebraic Geometry. In 1998 I received PhD in the same University with a thesis on Lie Algebras. In February 2000 I joined CMA-SMS here at ANU for a 2 year position as a PostDoc Fellow. My main interest has been theory of modular Lie algebras and related topics, and now I've jsut started studying cryptography.
