  Using High Level Profiling Data to Early Assess the Fault Tolerance of Complex Digital Components

  • 13 novembre 2026 (11:00 - 12:00)

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

  Orateur : Luc NOIZETTE - Nuclétudes (filiale Ariane group)

  This presentation outlines an innovative methodology for estimating the fault tolerance of complex components based on application profiling obtained using a high-level virtual platform.  A derating factor, derived exclusively from profiling metrics (e.g., lifetime in memory and registers), is calibrated using a reliability dataset collected from a set of benchmarks.  Applying it to test softwares[…]

  !!! Reporté !!! Encryption homomorphe sans bruit à l'aide de groupes

  • 26 juin 2026 (13:45 - 14:45)

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

  Orateur : Pierre Guillot - Ravel Technologies (dispo Université de Strasbourg, IRMA)

  Je vais rappeler les travaux de Nuida et Ostrovski sur l'utilisation des groupes pour l'élaboration de schémas cryptographiques homomorphes. Je vais présenter nos travaux qui fournissent des encodages à la fois plus efficaces et plus généraux, et qui déterminent exactement quels groupes peuvent être utilisés.   Puis je vais discuter GRAFHEN, un protocole qui utilise ces idées. Je dirai juste[…]

  Towards More Secure Large Language Models

  • 12 juin 2026 (11:00 - 12:00)

  • Inria Center of the University of Rennes - Petri/Turing room

  Orateur : Raouf Kerkouche - Inria Lille

  Large Language Models (LLMs) have achieved considerable success and are now widely used across multiple domains, highlighting their transformative impact on both technology and society. However, this widespread adoption also exposes LLMs to numerous security threats that can alter model behavior or degrade overall performance. To mitigate these threats, most research has focused on alignment[…]

  Opening Pandora's Box: White-Box Attacks on Microsoft's PhotoDNA Perceptual Hash Function

  • 05 juin 2026 (11:00 - 12:00)

  • Inria Center of the University of Rennes - Aurigny room

  Orateur : Diane Leblanc-Albarel - KU Leuven

  PhotoDNA is a widely deployed perceptual hash function used for the detection of illicit content such as Child Sexual Abuse Material (CSAM). In this talk, I will present our paper introducing the first mathematical description of Alleged PhotoDNA, a function that reproduces the outputs of PhotoDNA. Our analysis reveals several structural weaknesses: the function is piece-wise linear and[…]

  Onysis: A secure European SoC FPGA 

  • 13 novembre 2026 (10:00 - 11:00)

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

  Orateur : Adrien GRASSEIN - Nanoxplore

  Developed in collaboration with the DGA, the Onysis project introduces a European SoC FPGA designed to embed advanced hardware security features. This presentation will provide an overview of the Onysis architecture, focusing specifically on its native mechanisms to protect critical systems. We will detail the implementation of its integrated security subsystem, covering the secure boot sequence[…]
