Description
Security in embedded systems requires the choice of a suitable implementation platform. For some systems, a general purpose microprocessor satisfies the requirements, but when high performance is the main criterium, cryptographic coprocessors in hardware are indispensable. When very high performance is required or when a high volume of coprocessors is needed, ASICs (Application Specific Integrated Circuits) are chosen as implementation platforms. In this case, the reconfigurability of FPGAs (Field Programmable Gate Arrays) is only used for prototyping. However, because of the efforts of FPGA manufacturing companies, the performance gap between ASICs and FPGAs becomes smaller and smaller. FPGAs have become heterogeneous systems with a variety of dedicated resources such as multiplier blocks, DSP slices, RAM blocks,... This explains the trend that FPGAs are more and more used as end products. Following this trend, the need for specific FPGA architectures can be justified. This presentation focuses on cryptographic coprocessor design, optimized for FPGAs.

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.
