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 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 the candidates of the NIST lightweight comptetition. I am also studying some generic attacks on SPN ciphers, such as rectangle, boomerang, square or differential-linear attacks. You can find my resumé in french here.Teaching
