  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[…]

  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[…]

  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[…]

  Sécurité physique du mécanisme d'encapsulation de clé Classic McEliece

  Le mécanisme d'encapsulation de clé Classic McEliece faisait partie des candidats toujours en lice au dernier tour du processus de standardisation de la cryptographie post-quantique initié par le NIST en 2016. Fondé sur les codes correcteurs d'erreurs, en particulier autour du cryptosystème de Niederreiter, sa sécurité n'a pas été fondamentalement remise en cause. Néanmoins, un aspect important du[…]

  Embedded programs (including those on smart cards) are often developed in C and then compiled for the embedded processor. Sometimes they are modified by hand to incorporate countermeasures (fault attacks, etc.), but care must be taken to ensure that this does not disrupt normal program execution and that the countermeasure is actually adequate for blocking the attacks.In the process, it is[…]
