Augustin Bariant
Ph.D student in symmetric cryptography at INRIA de Paris
WHO AM I
Former student in Ecole Polytechnique, I completed a double degree with KTH Royal Institute of Technology in Stockholm in 2021. In march 2021, I started a Ph.D in symmetric cryptography in the team COSMIQ of Inria de Paris, under the supervision of Gaëtan Leurent. I am currently working on the cryptanalysis of lightweight symmetric cryptography primitives, especially on candidates of the NIST lightweight comptetition. I am a big fan of boomerang attacks, which I spent a lot of time understanding and studying. I am also interested in classical attacks on SPN ciphers, such as impossible differential, meet-in-the-middle, square or differential-linear attacks, as well as algebraic attacks on arithmetization-oriented ciphers. You can find my (outdated) resumé in french here.Teaching
