Petr Lisonek

Petr Lisonek is a Professor in the Department of Mathematics at Simon Fraser University (SFU), part of the Faculty of Science. His research focuses on applications of algebraic and combinatorial methods in cryptography, error-correcting codes, steganography, and computer algebra.

Education: Ph.D. in Computer Science from Johannes Kepler University (1994).

Research Interests:

• Non-linear functions in symmetric cryptography and their algebraic/combinatorial constructions.
• Design of error-control codes for classical and quantum channels using finite fields and finite geometries.
• Steganographic schemes leveraging linear codes for secure information hiding.
• Algorithmic aspects of cryptography and coding theory in computer algebra systems.

Recent Research Trends: Recent work emphasizes quantum code construction, cryptographic APN permutations, and foundational results in quantum contextuality (Kochen-Specker sets). Publications span topics like twisted codes, maximal nonassociative quasigroups, and minimal magic sets in quantum mechanics.
