    On the average hardness of SIVP for module lattices of fixed rank

    Speaker : Radu Toma - Sorbonne Université

    In joint work with Koen de Boer, Aurel Page, and Benjamin Wesolowski, we study the hardness of the approximate Shortest Independent Vectors Problem (SIVP) for random module lattices. We use here a natural notion of randomness as defined originally by Siegel through Haar measures. By proving a reduction, we show it is essentially as hard as the problem for arbitrary instances. While this was[…]

    Speaker : Min-Yi Shen - No Affiliation

    One of the fundamental hardness assumptions underlying isogeny-based cryptography is the problem of finding a non-trivial endomorphism of a given supersingular elliptic curve. In this talk, we show that the problem is related to the problem of finding a splitting of a principally polarised superspecial abelian surface. In particular, we provide formal security reductions and a proof-of-concept[…]

    Speaker : Aymeric Fromherz - Inria

    From secure communications to online banking, cryptography is the cornerstone of most modern secure applications. Unfortunately, cryptographic design and implementation is notoriously error-prone, with a long history of design flaws, implementation bugs, and high-profile attacks. To address this issue, several projects proposed the use of formal verification techniques to statically ensure the[…]

    The Design and Implementation of a Virtual Firmware Monitor

    Speaker : Charly Castes - EPFL

    Low level software is often granted high privilege, yet this need not be the case. Although vendor firmware plays a critical role in the operation and management of the machine, most of its functionality does not require unfettered access to security critical software and data. In this paper we demonstrate that vendor firmware can be safely and efficiently deprivileged, decoupling its[…]
