    Cryptanalytical extraction of complex Neural Networks in black-box settings

    • March 28, 2025 (10:00 - 11:00)

    • Inria Center of the University of Rennes - Espace de conférences

    Speaker : Benoit COQUERET - INRIA, Thales CESTI

    With the widespread development of artifical intelligence, Deep Neural Networks (DNN) have become valuable intellectual property (IP). In the past few years, software and hardware-based attacks targetting at the weights of the DNN have been introduced allowing potential attacker to gain access to a near-perfect copy of the victim's model. However, these attacks either fail against more complex[…]

    The influence of flicker noise on ring oscillator-based TRNGs

    • December 20, 2024 (11:00 - 12:00)

    • Inria Center of the University of Rennes - Espace de conférences

    Speaker : Licinius-Pompiliu BENEA - Univ. Grenoble Alpes, CEA, LETI

    Ring oscillators (ROs) are often used in true random number generators (TRNGs). The jitter of their clock signal, used as a source of randomness, stems from thermal and flicker noises. While thermal noise jitter is often identified as the main source of randomness, flicker noise jitter is not taken into account due to its autocorrelated nature which greatly complexifies modelling. However, it is a[…]

    Un protocole SMPC de curation de données d'entrainement et sa fragilité aux hypothèses de sécurité...

    • December 06, 2024 (11:00 - 12:00)

    • Inria Center of the University of Rennes - Métiviers room

    Speaker : Marc-Olivier Killijian - Université du Québec à Montréal

    ... ou "Sécurité et insécurité - dans quel état j’erre, ai-je bien rangé mon modèle de sécurité ?" De nos jours, les sources de données, et leurs curateurs, sont répartis à travers le monde. Il arrive que les propriétaires de ces données souhaitent collaborer entre eux afin d’augmenter la qualité de ces données, particulièrement avant d’entrainer des modèles d’apprentissage machine.Dans cet exposé[…]

    Solving the Tensor Isomorphism Problem for Special Orbits

    • November 08, 2024 (13:45 - 14:45)

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

    Speaker : Valerie Gilchrist - ULB

    Public key cryptography relies on using mathematical functions that are easy to compute but hard to invert. A recent work by D'Alconzo, Flamini, and Gangemi attempted to build such a function from tensors and use it to create a commitment scheme. In this talk, we will review their construction and present an attack on it, rendering it completely insecure. We will also offer an approach to[…]
