Description

    Patrick Dehornoy - Université de Caen

Au cours des années récentes, la définition de plusieurs protocoles cryptographiques reposant sur l'utilisation des groupes de tresses a suscite un enthousiasme soudain, puis une désaffection presque aussi rapide lorsqu'il a été réalisé que la difficulté du problème de base n'est pas démontrée. On essaiera de faire le point sur ces questions de façon plus nuancée.

  • CryptoVerif: a computationally-sound security protocol verifier

    Orateur : Bruno Blanchet - Inria

    CryptoVerif is a security protocol verifier sound in the computational model of cryptography. It produces proofs by sequences of games, like those done manually by cryptographers. It has an automatic proof strategy and can also be guided by the user. It provides a generic method for specifying security assumptions on many cryptographic primitives, and can prove secrecy, authentication, and[…]

  • Structured-Seed Local Pseudorandom Generators and their Applications

    • 05 décembre 2025 (13:45 - 14:45)

    Orateur : Nikolas Melissaris - IRIF

    We introduce structured‑seed local pseudorandom generators (SSL-PRGs), pseudorandom generators whose seed is drawn from an efficiently sampleable, structured distribution rather than uniformly. This seemingly modest relaxation turns out to capture many known applications of local PRGs, yet it can be realized from a broader family of hardness assumptions. Our main technical contribution is a[…]

  • Post-Quantum Public-Key Pseudorandom Correlation Functions for OT

    • 12 décembre 2025 (13:45 - 14:45)

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

    Orateur : Mahshid Riahinia - ENS, CNRS

    Public-Key Pseudorandom Correlation Functions (PK-PCF) are an exciting recent primitive introduced to enable fast secure computation. Despite significant advances in the group-based setting, success in the post-quantum regime has been much more limited. In this talk, I will introduce an efficient lattice-based PK-PCF for the string OT correlation. At the heart of our result lie several technical[…]

  • Predicting Module-Lattice Reduction

    • 19 décembre 2025 (13:45 - 14:45)

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

    Orateur : Paola de Perthuis - CWI

    Is module-lattice reduction better than unstructured lattice reduction? This question was highlighted as `Q8' in the Kyber NIST standardization submission (Avanzi et al., 2021), as potentially affecting the concrete security of Kyber and other module-lattice-based schemes. Foundational works on module-lattice reduction (Lee, Pellet-Mary, Stehlé, and Wallet, ASIACRYPT 2019; Mukherjee and Stephens[…]
