LIP6 ALMASTY

The Almasty team was created in April 2015. The Almasty team is mainly oriented toward the use of algorithmic and effective mathematic techniques to propose and improve modern cryptosystems and assess their security levels. Toward this goal, it makes use of numerous mathematical tools and develop algorithms to improve computations beyond what is reachable with state-of-the-art methods. The research activity of the Almasty team addresses the following topics: provable security, (pseudo-)randomness in cryptography, security against side-channel attacks, secure multi-party computation, (post-)quantum cryptography, cryptanalysis, high-performance computing, ...
