    L’empoisonnement de données semble-t-il un risque réaliste ?

    • September 23, 2022

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

    Speaker : Adrien Chan-Hon-Tong (ONERA)

    Les attaques adversaires ont rencontré un fort écho dans la communauté de vision par ordinateur. Pour autant, via ce type d’attaque, un hacker ne peut modifier le comportement de l’algorithme ciblé que localement. Inversement, l’empoisonnement de données est en mesure de modifier globalement le comportement de l’algorithme visé, et, il n’est pas forcément détectable par un opérateur notamment si[…]

    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[…]

    DroidGuard: A Deep Dive into SafetyNet

    • January 06, 2023

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

    Speaker : Romain Thomas (Quarkslab)

    SafetyNet is the Android component developed by Google to verify the devices’ integrity. These checks are used by the developers to prevent running applications on devices that would not meet security requirements but it is also used by Google to prevent bots, fraud and abuse.In 2017, Collin Mulliner & John Kozyrakis made one of the first public presentations about SafetyNet and a glimpse into the[…]

    Canadian and Québec approaches to contact tracing

    • December 11, 2020

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

    Speaker : Sébastien Gambs (Université du Québec à Montréal, Canada)

    Contact tracing applications have been deployed in many countries as a complementary measure to fight Covid-19 by enabling to automatically notify individuals who have been in contact with infected persons. However, the choice of the design of a particular application is not innocent as it has a direct impact on its security as well as on the privacy of its user. In this talk, I will review the[…]

    Learning-Based Network Intrusion Detection: an Imbalanced, Constantly Evolving and Timely Problem

    • October 07, 2022

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

    Speaker : Maxime Pelcat (INSA Rennes)

    Network intrusion detection systems (NIDS) observe network traffic and aim to pinpoint intrusions, i.e. effective threats on the integrity, availability or confidentiality of services and data provided by this network. There are two types of NIDS:1) signature-based intrusion detection systems that identify known intrusions by referring to an existing knowledge base, and2) anomaly-based intrusion[…]

    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.[…]
