Research 
I am currently working on symmetric cryptography,
and more precisely, my main research interest is the cryptanalysis
of arithmetizationfriendly symmetric primitives. These new primitives are
particularly innovative since they use nonlinear functions whose algebraic
representation remains very simple on a large finite field.
It is therefore not excluded that the implementation
constraints that have governed their design have introduced some security
flaws.
This is why, during the first year of my PhD, I have especially focused
on the study of the algebraic degree of one of these constructions:
the block cipher MiMC.
In addition to this mathematical analysis, I've also been interested in
practical attacks on other primitives like Rescue or Poseidon.
Then, I have joined the designer's side in creating Anemoi: our new family
of hash functions that exploit the link between arithmetizationorientation and
CCZequivalence.
