The Journey of Differential Meet-in-the-Middle Attacks (so far) In this talk, we will start discussing the importance of symmetric cryptanalysis, and some of its main open problems. Next, we will present differential MITM attacks, that were proposed in 2023, and
The numerical computation of spectral properties (Green functions, densities of states...) of periodic crystals relies on singular integrals in Fourier space. I will describe new algorithms to compute these integrals, with applications to solid state physics and connections to spectral
In this talk, I will present some results on unique continuation for semilinear wave and Schrödinger equations with analytic nonlinearities. After recalling some motivation and classical results on the topic, I will describe a new method, introduced in a joint
