Research
My research interests include the design and cryptanalysis of symmetric cryptographic algorithms, such as hash functions and authenticated encryption algorithms and their underlying primitives: permutations, (tweakable) block ciphers, etc. In my research, I am particularly interested in their “practical security”, which includes robustness against misuse and implementation attacks in addition to cryptanalytic security. I enjoy exploring mathematical aspects of cryptanalysis, useful tools and heuristics, and connections between cryptanalytic and physical attacks.
Online resources on selected research topics (see links for collaboration partners):
- Ascon, a family of authenticated ciphers and hash functions, winner in the “lightweight” category of the CAESAR competition and now competing in the NIST lightweight crypto standardization process
- ISAP, a lightweight authenticated cipher designed for robustness against side-channel attacks, now competing in the NIST lightweight crypto standardization process
- CASTLE tools, some of my research team’s cryptanalysis tools and source code for our papers
- Malicious SHA-1

Teaching
I teach cryptography as part of several undergraduate and graduate courses (see TUGRAZonline):
- Information Security (lecture: winter term 2022/23, 2021/22, 2020/21, 2019/20)
- Cryptography (lecture and practicals: winter term 2022/23, 2021/22, 2020/21)
- Cryptanalysis (lecture/seminar and practicals: summer term 2021/22 2020/21)
- Introduction to Scientific Working (seminar: winter term 2022/23, 2021/22, 2020/21)
You can find many of my lectures on Youtube.
Looking for a bachelor’s thesis, master’s thesis, or project in symmetric cypto, cryptanalysis, and practical security? Let me know, I’m always happy to discuss open topics!
