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 lightweight symmetric primitives, especially through integral and cube attacks.

During my first year, I analyzed the security of Ascon, one of the finalists of the NIST current standardization process for lightweight cryptography. I hope to eventually look at other candidates and/or cryptanalysis techniques.

Teaching

Besides, I am in charge of weekly tutorials at UVSQ (Université Versailles Saint-Quentin-en-Yvelines, Versailles, France).

• Introduction to (Python) programming (IN100) for first-year students (sept 2021 – jan 2022)
• Cryptography for third-year students (feb 2022 – may 2022)
• Complementary course in discrete mathematics for master students (sept 2022)
• Complementary course in algorithmic for master students (sept 2022)
• Mathematics for computer science (IN310) for second-year students (sept 2022 – dec 2022)
  • CC1 (oct 2022) sujet correction
  • CC2 (dec 2022) sujet correction
