Description

    Thomas Prest. - PQShield

Parmi les 26 schémas post-quantique toujours considérés pour standardisation par le NIST, 12 sont basés sur les réseaux (3 schémas de signature et 9 schémas de chiffrement). Cette présentation leur est consacrée. A haut niveau, tous peuvent être interprétés comme des instanciations directes de paradigmes bien établis. Mais une analyse plus attentive révèle que chacun d'eux fait des choix de conception qui impactent leur sécurité, efficacité et portabilité de manières distinctes; nous discuterons de ces choix et de leur impact. Finalement, je présenterai quelques astuces applicables à certains schémas spécifiques: dans *certains* contextes, elles permettent, moyennant des modifications minimales sur les schémas, d’améliorer leur cout en communication par un ou plusieurs ordres de grandeur.<br/> lien: rien

    Speaker : Charlotte Lefevre - Radboud University

    The Ascon authenticated encryption scheme and hash function of Dobraunig et al (Journal of Cryptology 2021) were recently selected as winner of the NIST lightweight cryptography competition. The mode underlying Ascon authenticated encryption (Ascon-AE) resembles ideas of SpongeWrap, but not quite, and various works have investigated the generic security of Ascon-AE, all covering different attack[…]

  • Comprehensive Modelling of Power Noise via Gaussian Processes with Applications to True Random Number Generators

    Speaker : Maciej Skorski - Laboratoire Hubert Curien

    The talk examines power noise modelling through Gaussian Processes for secure True Random Number Generators.   While revisiting one-sided fractional Brownian motion, we obtain novel contributions by quantifying posterior uncertainty in exact analytical form, establishing quasi-stationary properties, and developing rigorous time-frequency analysis. These results are applied to model oscillator[…]

    Speaker : Bruno Blanchet - Inria

    CryptoVerif is a security protocol verifier sound in the computational model of cryptography. It produces proofs by sequences of games, like those done manually by cryptographers. It has an automatic proof strategy and can also be guided by the user. It provides a generic method for specifying security assumptions on many cryptographic primitives, and can prove secrecy, authentication, and[…]
