    Where ML Security Is Broken and How to Fix It

    • February 03, 2023

    • Inria Center of the University of Rennes - - Room TBD

    Speaker : Maura Pintor (PRA Lab, University of Cagliari)

    To understand the sensitivity under attacks and to develop defense mechanisms, machine-learning model designers craft worst-case adversarial perturbations with gradient-descent optimization algorithms against the model under evaluation. However, many of the proposed defenses have been shown to provide a false sense of robustness due to failures of the attacks, rather than actual improvements in[…]

    Security and privacy in personal data management systems

    • January 28, 2022

    • Inria Center of the University of Rennes - - Room TBD

    Speaker : Nicolas Anciaux (INRIA)

    Personal Data Management Systems (called PDMS) provide individuals with a hardware and/or software solution to manage their data under control. From a data management and security/privacy perspective, the issues involved are complex and differ significantly from the traditional database setting. The emergence of trusted execution environments (such as Intel SGX) could be a game changer. This[…]

    Cryptographie légère intrinsèquement résistante aux attaques physiques pour l’Internet des Objets

    • May 25, 2018

    • CEA-Tech, Laboratoire Systèmes et Architectures Sécurisés (LSAS) - Salles Petri/Turing

    Speaker : Benjamin Lac

    Avec des applications telles que les smart phones , compteurs intelligents, capteurs et autres systèmes industriels de type SCADA, le nombre d objets connectés à Internet atteindrait les 20 milliards d ici 2020. Les contraintes de taille, coût et consommation ainsi que les problématiques de sécurité liées au déploiement de ces objets à si grande échelle ont mené à la conception de systèmes de[…]

    libecc: a flexible open-source ECC library for embedded devices

    • February 14, 2020

    • ANSSI - Salle Pétri/Turing

    Speaker : Ryad Benadjila et Arnaud Ebalard

    libecc is a software library for elliptic curves based cryptography (ECC), with an API supporting signature algorithms specified in the ISO14888-3 standard.Advanced usages of this library also include the possible implementation of elliptic curve based Diffie-Hellman protocols as well as any algorithm on top of prime fields based elliptic curves (or prime fields, or rings of integers).The[…]

    Une approche pour l’accélération matérielle pour le chiffrement homomorphe

    • December 14, 2018

    • CEA List

    Speaker : Joël Cathebras

    Le chiffrement homomorphe est un outil cryptographique permettant la manipulation de données en aveugle. Son utilisation généralisée permettrait de proposer des solutions de calcul déporté impliquant des données confidentielles, par exemple des données génomiques pour la médecine personnalisée. Cependant, le chiffrement homomorphe doit faire face à de grandes complexités mémoires et calculatoires.[…]

    Code-based postquantum cryptography : candidates to standardization

    • April 23, 2021

    • INRIA - Web-Conférence

    Speaker : Nicolas Sendrier

    At the third round of the NIST standardization process, three candidates remain with a security based on error correcting codes, all are key exchange mechanisms. We will explore them according to their security assumptions and properties. Among them, we find an historical scheme (Classic McEliece), as well as schemes using sparse and quasi-cyclic matrices (BIKE and HQC). We will examine pros and[…]
