Research


I am currently working on symmetric cryptography, and more specifically, my main research interest is the cryptanalysis of arithmetization-oriented symmetric primitives. In particular, I've been trying to better understand the mathematical properties of such primitives. During my PhD, I've also had the opportunity to design Anemoi, exploiting a link between arithmetization-orientation and CCZ equivalence.
