Maximiliane Weishäupl

PhD Student

I am a PhD student at the Chair for Data Security and Cryptography advised by Juliane Krämer. I received my M.Sc. and B.Sc. in Mathematics at University of Regensburg.

Research Interests

My research focuses on advanced security notions for various cryptographic primitives, particularly authenticated encryption, digital signature schemes, and key encapsulation mechanisms.
