    Speaker : Modou Sarry - IMT Atlantique

    Les dispositifs interconnectés tels que les réseaux de capteurs, la santé, les systèmes de contrôle distribués, l’internet des objets et les systèmes cyber-physiques sont de plus en plus répandus. Cette transition vers de petits appareils engendre de nouvelles préoccupations en matière de sécurité et de vie privée, car de nombreux algorithmes cryptographiques classiques ne répondent pas toujours[…]
  • Understanding and fighting fault injections with programming languages

    • September 27, 2024 (11:00 - 12:00)

    • Inria Center of the University of Rennes - - Petri/Turing room

    Speaker : Sébastien Michelland - Université Grenoble Alpes, Grenoble INP, LCIS

    Would your latest program produce correct results if I skipped a statement in it? Two? Corrupted a variable at random? Then it might not be robust against _fault injection attacks_, which target hardware directly and have such effects. To be fair, nothing really resists them; still, efforts in designing protections have come a long way, relying (perhaps surprisingly) in large part on hardening[…]

  • Acquisition and Exploitation of Traces from Connected Devices

    • September 27, 2024 (10:00 - 11:00)

    • Inria Center of the University of Rennes - - Petri/Turing room

    Speaker : Francesco Servida - École des Sciences Criminelles, Université de Lausanne

    This presentation aims to give an overview of the traces that can be obtained from connected objects as witnesses or actors at a crime scene. Using several scenarios we cover the challenges of detecting connected devices, the relevant locations for data retrieval and the techniques for acquiring said data. We then present how such data can be useful in helping to understand the dynamics of events[…]

  • Elliptic curves for SNARK and proof systems

    • September 20, 2024 (13:45)

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

    Speaker : Aurore Guillevic - INRIA Rennes

    This talk is based on joint works with Diego Aranha, Youssef El Housni, and Simon Masson. Elliptic curves make possible in practice very interesting mechanisms of proofs. The security relies on the difficulty of the discrete log problem and variants. Succinct non-interactive arguments of knowledge (SNARK) are a very fruitful topic, so that given a sequence of instructions that can be quite large,[…]
  • From Deciding Knowledge to Intrusion Detection

    • September 13, 2024 (11:00 - 12:00)

    • Inria Center of the University of Rennes - - Petri/Turing room

    Speaker : Yannick Chevalier - Université de Toulouse

    By interpreting terms as distributions over strings, Abadi and Rogaway proved under suitable assumptions that indistinguishability in the computational setting, accepted as the impossibility for an observer to acquire knowledge from observing a protocol execution, is equivalent to formal equivalence in a symbolic setting. This result led to multiple results on “deciding knowledge” using static[…]
