Petr is an Associate Professor at the Masaryk University, Czech Republic. He engages in the research on randomness and pseudo-randomness and key distribution protocols usable for systems with multiple parties, often with devices significantly limited in performance capabilities like, e.g., cryptographic smart cards. He also focuses on utilization of secure hardware in complex scenarios and the development of secure applications on such platforms. He dreams about a more open and transparent world of cryptographic smartcards.
