Teaching

I teach cryptography as part of several undergraduate and graduate courses (see TUGRAZonline):

Information Security (exercises: winter term 2024/25, 2023/24, 2022/23)
Cryptanalysis (lecture/seminar and practicals: summer term 2025, 2024, 2023)
Secure Software Development (2 lectures in winter term 2023/24, 2022/23)

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!
