Description
We present a technique for the verification of cryptographic protocols, based on an abstract representation of the protocol by a set of Horn clauses, and on a resolution algorithm on these clauses. This technique allows a flexible encoding of many cryptographic primitives. It can verify a wide range of security properties of the protocols, such as secrecy, authenticity, and limited cases of process equivalences, in a fully automatic way. Furthermore, the obtained security proofs are valid for an unbounded number of sessions of the protocol, in parallel or not.

Random lattices that are modules over the ring of integers
Orateur : Nihar Gargava - Institut de Mathématiques d'Orsay
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[…]-

Schéma de signature à clé publique : Frobénius-UOV
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[…] -
