Research Activity

I am currently associate professor at Jussieu's University (UPMC) in the project-team POLSYS which is common between and INRIA Paris. My research area is at the intersection of cryptography and symbolic computation. I am mainly interested by evaluating the security of cryptographic primitives by means of algebraic methods. The idea is to model a cryptographic primitive as a system of algebraic equations. This general approach is called algebraic cryptanalysis. Once this modeling is done, the problem is then to solve an algebraic system. Gröbner bases is a classical technic to do so. In POLSYS, we have applied this approach to evaluate the hardness of various problems underlying the security of most quantum-resistant algorithms : multivariate schemes, code-based as well as lattice-based schemes. It apperas that algebraic cryptanalysis an important tool for evaluating the security of quantum-resistant algorithms. I am also involved and motivated by industrial transfert. I am external scientific advisor for Kryptnostic, member of the CSA quantum-safe security working group and member of the quantum-safe cryptography specification group of the European Telecommunications Standards Institute (ETSI).
