About me

I'm currently a post-doc under the supervision of Gregor Leander .
I obtained my PhD on the October, 22 2019, under the supervision of Pierre-Alain Fouque and Patrick Derbez.
My topic of research is symmetric cryptography, especially Division Property, Differential Attacks, Boomerang and others.
I'm also interested in constraint programming tools (CP, MILP, etc.) and their applications to symmetric cryptography.




All of these courses were done at Université de Rennes 1.
For most of them, I was in charge of some exercise courses (TD), practical courses (TP), as well as writing some of the exercise sheets for some (especially INF1).

  • INF1 : Introduction to imperative programming based on the Java language for first year students.

  • OIA : Follow-up course of INF1 for maths students. Introduction to complexity, sorting algorithms,...

  • BCS : Fifth year course for non-crypto students. Basic implementation of some cryptographic primitives and attacks in C (CSS, MD4, AES) and Python (RSA), as well as some tools for cryptography (writing a big number library in C, using openssl,...)

  • SECU : Fourth year course. Introduction to cryptography, HTML/PHP vulnerabilities, openssl, PGP etc.

  • APS : Follow-up course of SECU. Emphasis on cryptanalysis (CSS, correlation attacks, padding oracle attacks, etc.)
