Description
Achieving secure and reliable communication in a wireless network is especially challenging when the end devices are energy constrained. Traditionally, forward error correcting codes (FECs) and encryption have been used to correct errors and provide secrecy respectively, in a tandem system. This conventional approach could be potentially less efficient than a joint system (where both functionalities are combined into a single paradigm). The key question is: can the two operations be combined safely and if so what are the impacts of such a joint construction on both error correction capability as well as security?<br/> In this talk we will show that it is indeed possible to combine error correction and encryption in the specific case of block ciphers. The core of this construction is a new class of maximum distance separable (MDS) codes, which we call high diffusion (HD) codes, that incorporate both a criterion for optimal diffusion as well as a criterion for error correction. We will present the fundamental ideas behind HD codes and discuss the construction of the codes and block ciphers based on these codes. Security and error correction capabilities of the joint system will be discussed. Stream mode construction of the cipher will also be presented along with some simulation results.

Random lattices that are modules over the ring of integers
Speaker : 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
Speaker : 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[…] -
