Aarhus Crypto Seminar

We have a seminar series where members and visitors of the group give talks about recent research in cryptology and information security.

Everyone is welcome to attend the seminars!

The seminars take place on Thursdays from 13:30 to 14:30 in Nygaard-295, Finlandsgade 21, 8200 Aarhus N.    

A list of upcoming and previous talks is below. Talks prior to Autumn 2020 can be found here
