Reinhard Lüftenegger
BSc MScCryptology & Privacy, PhD Candidate

Research
I research algebraic cryptanalysis of block ciphers and hash functions and resulting implications on design choices. In particular, I work on Gröbner basis and higher-order differential attacks, boolean functions and interpolation attacks. Furthermore, I gradually develop towards the field of Elliptic Curve Cryptography, with a focus on Isogeny-Based Post-Quantum Cryptography.
Teaching
I teach cryptography as part of the graduate course:
- AK IT-Security 2 (seminar: winter term)
