Seminar Advanced Topics in Crytography

This course is listed in Aachen Campus as Seminar Advanced Topics in Cryptography and in Bonn Basis as Seminar Advanced Topics in Cryptography.


Prof. Dr. Joachim von zur Gathen


Michael Nüsken

Time & Place

First meeting: Wednesday, 09 April 2014.


Basic knowledge of cryptography and fast understanding of mathematical and computer science topics is required.


The final topic is not yet determined.  Previous instantiations dealt with fuzzy coding theory, Zero-Knowledge, PCP, ellitpic curve theory, analytical number theory, latest discrete logarithm records, ...  In any case the topic will try to dig deeper than what you expect in a standard course or seminar.


The chosen topic is
