History of the Aarhus Crypto Group

This is an unofficial page for the "Cryptography and Security" research group mantained by Claudio Orlandi. The aim of this page is to list everyone that is (or has been) affiliated with the Crypto group of the Department of Computer Science of Aarhus University.

The official page of the Cryptography and Security Group is generated automatically and only lists current members.

This is a manually generated page. If you find any omission, mistake or if you have old pictures of the group please write to orlandi at cs.au.dk

Where Are We Now?

This is a map of current locations of the previous members of the group who are holding a long-term research position.

Visitors

This list only includes long term visitors, defined arbitrarily by me as the people who spent one month or more with the group. Also, note that this is a very partial list: I have very little info about who visited the group before 2007. If you visited the group but are not in the list just send me an email.
