Research

My research interests include practical aspects of information security such as constructing and attacking cryptographic implementations as well as more theoretic aspects such as designing cryptographic schemes that feature robustness against physical attacks in addition to cryptanalytic security. I co-designed ISAP, a lightweight authenticated cipher that is currently competing in the 2nd round of the NIST lightweight crypto standardization process and gives out-of-the-box strong guarantees against various kinds of physical attacks like fault injection and power analysis.Online resources on selected research topics (see links for collaboration partners):

Teaching

I currently teach a graduate course that focuses on implementing and attacking secure cryptographic implementations for industrial applications:
