  Blockchain and digital currencies: between European regulation and technological challenges

  • 05 décembre 2025 (11:00 - 12:00)

  • Inria Center of the University of Rennes - Aurigny room

  Orateur : Loïc Miller - CentraleSupélec

  As the European Union develops a legal framework for crypto-assets and data protection, the technological question underlying the emergence of a genuine digital currency remains open. Blockchain today stands as an interdisciplinary field of study at the crossroads of computer science, economics, and law. This presentation will place the ongoing regulatory framework in perspective with the[…]

  Algorithms for post-quantum commutative group actions

  • 27 mars 2026 (13:45 - 14:45)

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

  Orateur : Marc Houben - Inria Bordeaux

  At the historical foundation of isogeny-based cryptography lies a scheme known as CRS; a key exchange protocol based on class group actions on elliptic curves. Along with more efficient variants, such as CSIDH, this framework has emerged as a powerful building block for the construction of advanced post-quantum cryptographic primitives. Unfortunately, all protocols in this line of work are[…]

  Attacking the Supersingular Isogeny Problem: From the Delfs–Galbraith algorithm to oriented graphs

  • 23 janvier 2026 (13:45 - 14:45)

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

  Orateur : Arthur Herlédan Le Merdy - COSIC, KU Leuven

  The threat of quantum computers motivates the introduction of new hard problems for cryptography.One promising candidate is the Isogeny problem: given two elliptic curves, compute a “nice’’ map between them, called an isogeny.In this talk, we study classical attacks on this problem, specialised to supersingular elliptic curves, on which the security of current isogeny-based cryptography relies. In[…]

  Post-Quantum Public-Key Pseudorandom Correlation Functions for OT

  • 12 décembre 2025 (13:45 - 14:45)

  • Salle Guernesey à l'ISTIC

  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[…]

  What you never wanted to know about vulnerability databases

  • 21 novembre 2025 (10:00 - 11:00)

  • Inria Center of the University of Rennes - Room Métivier

  Orateur : Henrik Plate - Endor Labs

  Vulnerability databases play a crucial role in modern software security, serving as the backbone for Application Security (AppSec) and Software Composition Analysis (SCA) tools. However, the accuracy and reliability of these databases vary significantly, often leading to misinformed security decisions. This talk explores the challenges associated with vulnerability databases, including incomplete[…]
