Dipl.-Ing. BSc

Secure Systems, Postdoctoral Researcher

I am a postdoctoral researcher at Graz University of Technology in Austria.

My research interests include practical aspects of information security such as designing and attacking cryptographic implementations, as well as more theoretic aspects such as mode-level security or formal verification. I am a co-author of ISAP, a lightweight authenticated encryption scheme that gives strong guarantees against various kinds of physical attacks based on fault injection and power analysis. ISAP reached the final round of the NIST standardization process for lightweight cryptography.


I am involved in a graduate course that focuses on implementing, as well as attacking cryptographic implementations. The hardware part of this course covers power analysis (DPA/SPA), fault attacks (DFA/SIFA), and corresponding countermeasure techniques. Students receive real hardware for conducting all these experiments.
