    Updatable Encryption from Group Actions

    • January 24, 2025 (13:45 - 14:45)

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

    Speaker : Maxime Romeas - ANSSI

    Updatable Encryption is a variant of symmetric encryption that allows to rotate the encryption key in the outsourced storage setting while minimizing the bandwith used. Indeed, any third party can update ciphertexts to the new key using a token provided by the key holder. UE schemes aim at providing strong confidentiality guarantees against adversaries that can corrupt keys and tokens.  In this[…]

    Les ONG clament qu’elles ne sont pas des cibles (« not a target »), et plaident pour un arrêt des enlèvements d’humanitaires et des bombardements d’hôpitaux. Ajoutons que ce slogan est maintenant décliné dans une version « modernisée » : les ONG ne sont pas des cibles numériques (« not a digital target »). Ce slogan constitue un appel à stopper les cyberopérations contre les ONG, qui sont[…]

    11h30  Katharina Boudgoust (CR CNRS, LIRMM) : The Power of NAPs: Compressing OR-Proofs via Collision-Resistant HashingProofs of partial knowledge allow for proving the validity of t out of n different statements without revealing which ones those are. In this presentation, we describe a new approach for transforming certain proofs system into new ones that allows for proving partial knowledge. The[…]

    Measurement the thermal component of clock jitter used as entropy source by TRNGs

    • February 28, 2025 (11:00 - 12:00)

    • Inria Center of the University of Rennes - - IRISA - Salle Aurigny (D165)

    Speaker : Arturo GARAY - STMicroelectronics

    Introduction Measuring the thermal component of clock jitter as an entropy source for True Random Number Generators (TRNGs) is compulsory for the security and evaluation of clock-jitter based TRNGs. However, identifying and isolating the local thermal noise component from other noise sources, particularly flicker noise, while performing a precise measurement remains a challenge. Current[…]

    Speaker : François Sarrazin, Pierre Granier - University of Rennes, IETR (UMR 6164)

    Electromagnetic leakage eavesdropping is an increasingly accessible attack vector due to the democratization of software-defined radio. "TEMPEST" attacks rely on passively listening to the unwanted electromagnetic emanations of a target (computer screen, low speed USB peripheral…) in order to retrieve the transmitted data. However, the range and properties of such leakages are unpredictable.[…]
