The Applied Cryptography Group at Orange Innovation is split between three research sites: Caen, Châtillon, and Cesson-Sévigné. We work in an academic environment but we focus significant efforts on both the application and practicality of our work. Current research interests include symmetric and asymmetric algorithms, primitives and protocols for constrained environments, distributed cryptography for privacy and voting, as well as software and content protection.
