Description
At PQShield, we've developed dedicated coprocessor(s) for lattice schemes, hash-based signatures, and code-based cryptography. These cryptographic modules are commercial rather than academic and designed to meet customer specifications such as a specific performance profile or Common Criteria and FIPS security certification requirements. Hardware implementations of legacy RSA and Elliptic Curve cryptography were generally just "big integer" engines. Post-quantum algorithms use a much broader range of primitive operations and are generally more complex.<br/> Monolithic hardware implementations are self-contained modules implementing the entire algorithm. A monolithic implementation has a clear security boundary but will lead to inflexibility and a relatively large area. On the other hand, a co-design approach will offload only those computations to special memory-mapped peripherals or custom instructions that benefit from it the most, e.g., SHAKE or large polynomial/vector/matrix circuitry. We discuss our experiences with both of these approaches, drawing from our engineering experience.

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.
