Number Theory Afternoon at AIMS South Africa

Monday, 28 November 2016


Speaker 1: Prof Neil Koblitz, University of Washington

Time: 14.30 – 15.30

Title: Introduction to some computer-science aspects of cryptography


Abstract:

Using graph theory (perfect codes, related to error-correcting codes) a cryptosystem based on an NP-complete problem is constructed, (but without going into any detail on NP-completeness). The reduction from one problem to another, polynomial time vs exponential blow-up, message-recovery attacks on a cryptosystem, key-recovery attacks, chosen-ciphertext attacks will be presented.


Tea/Coffee: 15.30 – 16.00

Speaker 2: Dr Gareth Boxall, Stellenbosch University
