Les cyber opérations, entre opportunités stratégiques et contraintes opérationnelles
Orateur : 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[…] -
Key recovery from partial information
Orateur : 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[…] -
Unique CAD-compatible SCA-security mechanisms, externally amplified coupling (EAC) attacks and (some) connection
Orateur : 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
Orateur : Markku-Juhani Saarinen
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[…] -

Code-based postquantum cryptography : candidates to standardization
Orateur : Nicolas Sendrier - INRIA
At the third round of the NIST standardization process, three candidates remain with a security based on error correcting codes, all are key exchange mechanisms. We will explore them according to their security assumptions and properties. Among them, we find an historical scheme (Classic McEliece), as well as schemes using sparse and quasi-cyclic matrices (BIKE and HQC). We will examine pros and[…]
