  • Key recovery from partial information

    • IRMAR - Université de Rennes - Campus Beaulieu Bat. 22, RDC, Rennes - Amphi Lebesgue

    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[…]
  • Unique CAD-compatible SCA-security mechanisms, externally amplified coupling (EAC) attacks and (some) connection

    • June 25, 2021

    • Bar-Ilan University (BIU) - Web-Conférence

    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[…]
  • Code-based postquantum cryptography : candidates to standardization

    • April 23, 2021

    • INRIA - Web-Conférence

    Speaker : Nicolas Sendrier

    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[…]

  • Lattice-based NIST candidates: abstractions and ninja tricks

    • April 23, 2021

    • IRMAR - Université de Rennes - Campus Beaulieu Bat. 22, RDC, Rennes - Amphi Lebesgue

    Speaker : Thomas Prest - PQShield

    I will present the remaining lattice-based candidates for standardization by NIST (2 signature schemes, 5 encryption schemes). At a high level, these can all be interpreted as straightforward instantiations of decades-old paradigms. But when we look under the hood, all of them make design choices which impact their security, efficiency and portability in distinct manners; we will discuss these.[…]
