We are based at the Faculty of Mathematics, Informatics and Mechanics of the University of Warsaw, where we do research and teach crypto-related courses.


We are mostly interested in the foundations of cryptography and data security, in particular in provably-secure leakage- and tamper-resilient cryptography, cryptographic countermeasures against malicious software attacks, blockchain and smart contracts.

The group leader is Stefan Dziembowski.

Our research and teaching has been supported by: the European Research Council (ERC), the Foundation for Polish Science (FNP), the National Science Centre (NCN), the COST Actions, Intel, and Ethereum Foundation.
