Research

My research focuses on cryptography applied to cybersecurity.

I currently work on several axes:

• Security of data in the cloud

  Through advanced encryption primitives such as homomorphic encryption or functional encryption.

• Privacy protection in contactless services

  Through anonymous and accountable authentication mechanisms, using cryptographic tools such as group signatures or blind signatures.

• Security of constrained environments (IoT, V2X)

  With low-cost cryptographic authentication and key-agreement protocols, suited to the limited resources of certain devices.

• Resistance to quantum computers

  Applied across all of these contexts, to anticipate the cryptographic systems of tomorrow.

Over the course of my research, I have supervised around fifteen PhD students, most of them under CIFRE contracts. I have also taken part in and managed numerous collaborative projects funded by the French National Research Agency (ANR, projects PACE and SIMPATIC) or the European Commission (SUPERCLOUD, PAPAYA and PROMETHEUS). The latter received numerous awards in the NIST post-quantum cryptography competition, as well as recognition from the French Ministry of Higher Education and Research.
