Pierre Briaud

I am a second-year PhD student in the Inria project-team COSMIQ, working under the supervision of Jean-Pierre Tillich.

My research focusses on algebraic cryptanalysis of code-based and multivariate cryptosystems. Outside of my PhD topic, I am more generally interested in algebraic aspects of post-quantum cryptography.
