Description

  • Orateur

    Valerie Gilchrist - ULB

Public key cryptography relies on using mathematical functions that are easy to compute but hard to invert. A recent work by D'Alconzo, Flamini, and Gangemi attempted to build such a function from tensors and use it to create a commitment scheme. In this talk, we will review their construction and present an attack on it, rendering it completely insecure. We will also offer an approach to repairing it.

The talk is based on the work from https://eprint.iacr.org/2024/337, but no prior knowledge is necessary.

    We investigate the average number of lattice points within a ball where the lattice is chosen at random from the set of unit determinant ideal or modules lattices of some cyclotomic number field. The goal is to consider the space of such lattice as a probabilistic space and then study the distribution of lattice point counts. This is inspired by the connections of this problem to lattice-based[…]

    Orateur : Gilles Macario-Rat - Orange

    L'exposé présente un schéma de signature à clé publique post-quantique inspiré du schéma UOV et introduisant un nouvel outil : les formes de Frobénius. L'accent est mis sur le rôle et les propriétés des formes de Frobénius dans ce nouveau schéma : la simplicité de description, la facilité de mise en oeuvre et le gain inédit sur les tailles de signature et de clé qui bat RSA-2048 au niveau de[…]

    Orateur : Xavier Bonnetain - Inria

    BEANIE is a tweakable block cipher recently published at ToSC aiming for memory encryption of microcontroller units. In line with this goal, it handles small plaintexts of only 32 bits and has a low latency. In this paper, we propose the first third-party analysis of the two variants of BEANIE. By carefully leveraging structural properties of the cipher and taking advantage of its distinctive[…]
