Description
In this talk we discuss the state of the art and progress in cryptographic algorithms such as encryption algorithms and digital signature techniques. We present at a high level the challenges to the designers (and users) of cryptographic algorithms and we discuss the major components of the solution, that is, research, standardization, and open evaluation. We also discuss the status of the NESSIE project. NESSIE (New European Schemes for Signature, Integrity and Encryption) is a 40-month research project (2000-2003) which intends to put forward a new generation of strong cryptographic algorithms, which have been obtained after an open call and an open evaluation process. We will also discuss a number of open problems identified within the NESSIE project.

!!! Reporté !!! Encryption homomorphe sans bruit à l'aide de groupes
Speaker : Pierre Guillot - Ravel Technologies (dispo Université de Strasbourg, IRMA)
Je vais rappeler les travaux de Nuida et Ostrovski sur l'utilisation des groupes pour l'élaboration de schémas cryptographiques homomorphes. Je vais présenter nos travaux qui fournissent des encodages à la fois plus efficaces et plus généraux, et qui déterminent exactement quels groupes peuvent être utilisés. Puis je vais discuter GRAFHEN, un protocole qui utilise ces idées. Je dirai juste[…]-

MIKE: An efficient and compact NIKE Based on a Commutative Monoidal Action
Speaker : Jonathan Komada Eriksen - COSIC, KU Leuven
Robert recently described a powerful correspondence between certain (Hermitian) modules and (polarized) abelian varieties, which simultaneously generalizes both the class-group action underlying protocols such as CSIDH, and the Deuring correspondence, underlying protocols such as SQIsign. Using this correspondence, he also proposed how to construct a post-quantum NIKE, called MIKE, which, at a[…]-
