I started a PhD in symmetric cryptography at INRIA Paris in October 2024, under the joint supervision of Léo Perrin and Gaëtan Leurent.

The goal of my PhD is to better understand and analyze the so-called STAPs (symmetric techniques for advanced protocols).

1. Research

I work on symmetric cryptography, specifically the analysis of STAPs.

1.1 Publications

• Attacking Split-and-Lookup-Based Primitives Using Probabilistic Polynomial System Solving : Applications to Round-Reduced Monolith and Full-Round Skyscraper. link
  • IACR Transactions on Symmetric Cryptology, 2025(3). Antoine Bak, Pierre Galissant, Guilhem Jazeron, Léo Perrin.

1.2 Talks

• Solving CICO-2 instances of Poseidon. Slides
  • Cryptanalysis of Algebraic Hash Functions, affiliated even of FSE 2025, March 2025, Roma, Italy. Site
  • Algebraic Hash Cryptanalysis Days, affiliated event of Eurocrypt 2025, May 2025, Madrid, Spain. Site
• Cryptanalysis of Monolith using rebound attacks. Slides
  • Journées Codages et Cryptographie (C2), April 2025, in Pornichet, France. Site
• Pahole : patching the rabbit hole. Slides
  • Joint work with Ouail Derghal, Martin Horth, Paul Houssel, Guilhem Jazeron, Ludovic Paillat, Robin Theveniaut, during REDOCS 2025.
  • This work resulted in finding a way to modify libbtf so that it would allow to convert DWARF information into BTF information for Go binaries.

2. Teaching

Below is a list of the tutorials I have taken part in:

• First semester of 2024:
  • Initiation to programming in Java (IP1), Université Paris Cité
  • Principles of Operation of Binary Machines (PF1), Université Paris Cité
• First semester of 2025:
  • Logic for computer science (LO5), Université Paris Cité
  • Modern applied cryptology (LACRYMO), in the form of a terminal-based role playing game with CTF-like puzzles.

3. Education

• 2024-now: Ph.D in Cryptography at Inria Paris.
• 2023-2024: second year of the Parisian Master of Research in Computer Science.
• 2021-2024: M.Sc. at Télécom Paris. Specialization in applied algebra (ACCQ track) and theoretical computer science (MITRO track)
• 2019-2021: preparatory school in mathematics, physics and computer science at Lycée Pierre de Fermat in Toulouse.

5. Misc.

• I enjoy photography, you can check my work on the following website: https://continentcontrescarpe.fr/
• I also enjoy CTFs a lot, and play some from time to time. I specialize in crypto challenges (obviously), but I also have a strong interest for binary exploitation and reverse engineering.
