A few words
In September 2021, I started doctoral studies under the supervision of Anne Canteaut & Léo Perrin, whithin Inria COSMIQ team.
I am currently focusing on cryptanalysis of symmetric primitives, especially lightweight ones. As an example, I analyzed the security of Ascon, which was announced in early 2023 as the winner of the NIST standardization process for lightweight cryptography.
I am also part of some workgroups whose purposes are to design new primitives either for new use cases or focused on extreme performances.
Teaching
Besides, I am in charge of weekly tutorials at UVSQ (Université Versailles Saint-Quentin-en-Yvelines, Versailles, France).
