    Jenny Cooley - University of Warwick

Soit F_q un corps fini à au moins 13 éléments. Soit S une surface cubique non singulière sur laquelle il y a au moins une droite rationnelle incluse. Il existe une façon de générer les points rationnels en utilisant des opérations tangentes et sécantes qui est similaire à la loi de composition du groupe de points d'une courbe elliptique. Dans cet exposé, nous utilisons le principe des tiroirs pour montrer que tout point rationnel de la surface peut alors être généré à partir d'un seul point.

    Speaker : Marie Bolzer - LORIA

    The problem of finding a minimal circuit to implement a given function is one of the oldest in electronics. In cryptography, the focus is on small functions, especially on S-boxes which are classically the only non-linear functions in iterated block ciphers. In this work, we propose new ad-hoc automatic tools to look for lightweight implementations of non-linear functions on up to 5 variables for[…]

    Speaker : Marc Houben - Inria Bordeaux

    At the historical foundation of isogeny-based cryptography lies a scheme known as CRS; a key exchange protocol based on class group actions on elliptic curves. Along with more efficient variants, such as CSIDH, this framework has emerged as a powerful building block for the construction of advanced post-quantum cryptographic primitives. Unfortunately, all protocols in this line of work are[…]

    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[…]
