On the hardness of the NTRU problem
Speaker : Alice Pellet-Mary - CNRS, Institut Mathématiques de Bordeaux
The NTRU problem is an algorithmic problem over structured lattices that was introduced by Hoffstein, Pipher, and Silverman more than 20 years ago, and which has been used to construct various cryptographic primitives. However, its relation to other lattice problems is still not well understood.<br/> In this talk, we will describe different variants of the NTRU problem, and study how they compare[…] -
Key recovery from partial information
Speaker : Gabrielle De Michelli - UC San Diego
The security of deployed protocols not only relies on the hardness of the underlying mathematical problem but also on the implementation of the algorithms involved. Many fast modular exponentiation algorithms have piled up over the years and some implementations have brought vulnerabilities that are exploitable by side-channel attacks, in particular cache attacks.<br/> In this talk, we consider[…] -
Les cyber opérations, entre opportunités stratégiques et contraintes opérationnelles
Speaker : Stéphane Taillat (Académie Militaire de Saint Cyr-Coëtquidan)
Le recours aux opérations numériques et au cyberespace s’est généralisé dans la gestion des crises et des conflits internationaux. Pour autant, aucune des cyber opérations étatiques ou prêtées à des États n’ont débouché sur des conflits armés ou sur une escalade significative des tensions. A ce titre, cette conférence cherche à s’interroger sur l’utilité stratégique des opérations numériques et du[…] -
Unique CAD-compatible SCA-security mechanisms, externally amplified coupling (EAC) attacks and (some) connection
Speaker : Itamar Levi
In this seminar I will first discuss unique computer aided design (CAD) compatible SCA security mechanisms. I will present an approach which can significantly increase the physical security-level of a design, be implemented with conventional design-tools and which does not require any special technological-support. The method consists with a correct by-design utilization of power-management[…] -
Post-Quantum Cryptography Hardware: Monolithic Implementations vs. Hardware-Software Co-Design
Speaker : Markku-Juhani Saarinen - PQShield
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[…] -
