Description

  • Speaker

    Oumar Diao - IRMAR

Dans cet exposé, nous ferons une présentation de certains aspects des calculs de couplages sur les jacobiennes de courbes algébriques utiles en cryptographie.<br/> Après un rappel sur les définitions mathématiques, nous présenterons l'algorithme de Miller qui permet de calculer efficacement les couplages de Weil et Tate. Puis, nous décrirons quelques améliorations algorithmiques apportées par F. Hess et al. et nous expliquerons comment accélérer encore leur algorithme dans le cas de courbes super-singulières.

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

    Speaker : 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

    • 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[…]
