Description
The Linux random number generator is part of the kernel since 1994. It collects entropy from user input, interrupts and disk movements and claims to output high quality random numbers. There are two different versions: /dev/random which blocks if the internal entropy count goes to zero and /dev/urandom which is faster since it produces as many bits as the user wants to. The only official definition of this RNG exists in the code itself which is subject to possible changes in new releases of the kernel. We want to give a detailed description of the current version. There exists previous attempts of describing this generator, especially the works of Barak and Halevi in 2005 and Gutterman et al. in 2006. However, the generator changed in the meantime and we want to describe it in more mathematical details.

Adelic reduction of module lattices
Orateur : Henry Bambury - DGA-MI et Inria Rennes
We give a strict generalisation of the LLL algorithm over number fields, based on the reduction theory of $GL(n)$ over the adele ring of a number field. Our algorithm is free of heuristics, with rigorous bounds on output quality and complexity. -- based on joint work with Seungki Kim, Changmin Lee and Phong Nguyen ---

European Cyber Week: atelier cryptographie post-quantique
Dans la continuité des éditions 2021, 2022 et 2024, la DGA — en partenariat avec CREACH LABS et avec le soutien de l'ANSSI, de l'IRISA, de l'IRMAR et du Pôle d'Excellence Cyber — organise la 4e édition de l'atelier consacré à la cryptographie post-quantique dans le cadre de l'European Cyber Week 2026. Attention, il faut s'inscrire (gratuitement) au préalable — s'inscrire à la conférence Les[…] -
Post-quantum day of the cryptography seminar
A scientific day devoted to post-quantum cryptography, held in the wake of the European Cyber Week, with talks more technical than those presented at the ECW.
