Description

  • Speaker

    Thomas Genet - IRISA

Dans cet exposé, je m'intéresserai uniquement aux failles logiques des protocoles cryptographiques, c'est à dire aux failles liées à un mauvais enchaînement des messages. Je ferai un rapide tour d'horizon des modèles et des techniques de vérification utilisés aussi bien pour la détection de telles failles que pour la preuve formelle de leur absence dans les protocoles. Je parlerais ensuite de la technique spécifique, basée sur la réécriture et les automates d'arbres, que nous utilisons dans le projet Lande pour approcher par le haut l'ensemble de toutes les exécutions possibles d'un protocole.

    At CRYPTO 2015, Kirchner and Fouque claimed that a carefully tuned variant of the Blum-Kalai-Wasserman (BKW) algorithm (JACM 2003) should solve the Learning with Errors problem (LWE) in slightly subexponential time for modulus q = poly(n) and narrow error distribution, when given enough LWE samples. Taking a modular view, one may regard BKW as a combination of Wagner’s algorithm (CRYPTO 2002), run[…]

  • CryptoVerif: a computationally-sound security protocol verifier

    • November 28, 2025 (13:45 - 14:45)

    • Batiment 32B salle 12

    Speaker : 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

    • December 05, 2025 (13:45 - 14:45)

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

    Speaker : 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[…]

  • Predicting Module-Lattice Reduction

    • December 19, 2025 (13:45 - 14:45)

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

    Speaker : 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[…]
