  Dissecting CRAFT, a full-round attack

  • 18 septembre 2026 (13:45 - 14:45)

  • Batiment 32A salle 15

  Orateur : Eran Lambooij - Inria

  I will present the first full-round key recovery attack on CRAFT, a block cipher introduced at ToSC 2019. The attack builds on the previous observation (ToSC 2026) that the state of CRAFT can be decomposed into two parts that barely exchange information. We transform this property into a dissection attack on the full-round cipher. This shows that in some cases we can elevate the dissection attack[…]

  Au-delà du narratif : l'OSINT comme lieu de convergence entre la lutte cyber et FIMI

  • 25 septembre 2026 (09:00 - 10:00)

  • Inria Center of the University of Rennes

  Orateur : Hervé LETOQUEUX & Nelly PAILLEUX - CheckFirst

  Depuis 2020, CheckFirst traque les opérations de manipulation de l'information en ligne via des enquêtes en source ouverte, et tente d'objectiver la façon dont les algorithmes de recommandation contribuent à façonner l'espace informationnel en ligne. Détecter et documenter une opération de manipulation de l'information (FIMI) exige de sortir du seul contenu : infrastructures de diffusion, comptes[…]

  Key Attack on the ACDGV Matrix Encryption Scheme

  • 25 septembre 2026 (13:45 - 14:45)

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

  Orateur : Anmoal Porwal - Technical University of Munich

  I will present our key-recovery attack on the ACDGV public-key encryption scheme proposed at ASIACRYPT 2024 by Aragon, Couvreur, Dyseryn, Gaborit, and Vinçotte. The secret key is a Gabidulin code hidden by appending random rows and columns and by left- and right-multiplication with invertible matrices. Our attack exploits the resulting algebraic structure to recover an equivalent secret key. It[…]

  Module Learning With Errors and Structured Extrapolated Dihedral Cosets

  • 02 octobre 2026 (13:45 - 14:45)

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

  Orateur : Jinwei Zheng - Télécom Paris

  The Module Learning With Errors (MLWE) problem is the fundamental hardness assumption underlying the key encapsulation and signature schemes ML-KEM and ML-DSA, which have been selected by NIST for post-quantum cryptography standardization. Understanding its quantum hardness is crucial for assessing the security of these standardized schemes.   Inspired by the equivalence between LWE and[…]

  Securing processor's microarchitecture against SCA in a post-quantum cryptography setting

  • 16 octobre 2026 (10:00 - 11:00)

  • IETR - University of Rennes - Campus de BEAULIEU - Bâtiment 11D, salle numéro 18

  Orateur : Vincent MIGLIORE - LAAS-CNRS

  Hardware microarchitecture is a well-known source of side-channel leakages, providing a notable security reduction of standard cryptographic algorithms (e.g. AES) if not properly addressed by software or hardware. In this talk, we present new design approaches to harden processor's microarchitecture against power-based side-channel attacks, relying on configurable and cascadable building blocks[…]
