    Adelic reduction of module lattices

    • November 13, 2026 (13:45 - 14:45)

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

    Speaker : Henry Bambury - DGA-MI et Inria Rennes

    We give a strict generalisation of the LLL algorithm over number fields, based on the reduction theory of  $GL(n)$ over the adele ring of a number field. Our algorithm is free of heuristics, with rigorous bounds on output quality and complexity.   -- based on joint work with Seungki Kim, Changmin Lee and Phong Nguyen --

    Module Learning With Errors and Structured Extrapolated Dihedral Cosets

    • October 02, 2026 (13:45 - 14:45)

    • Batiment 32A salle 8

    Speaker : 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[…]
