Workshop on

Factoring Large Numbers, Discrete Logarithms and Cryptanalytical Hardware

22-23 April 2008

Institut für Experimentelle Mathematik (IEM) 
Universität Duisburg-Essen

Description

On 22 and 23 April 2008 a workshop on factoring large numbers  with NFS and on DL-problems will take place at the Institute fuer Experimentelle Mathematik in Essen. The workshop is dedicated to present recent results  and  exchange  ideas in these topics concerning both theory, hard- and software aspects.

Everyone interested in these topics is heartily invited to come!

Organiser: G. Frey
