Étude des cellules oscillantes pour la génération d’aléa dans les circuits électroniques numériques
Speaker : Ugo Mureddu
Les objets connectés sont omniprésents dans notre société actuelle (ex : véhicules, transports en commun, santé, domotique, smartphone, moyen de paiement, etc.). La connexion et l’accès à distance des appareils d’usage quotidien améliore considérablement notre confort et notre efficacité dans notre vie professionnelle comme personnelle. Cependant, cela peut également nous confronter à des[…] -

Lattice-based NIST candidates: abstractions and ninja tricks
Speaker : Thomas Prest
I will present the remaining lattice-based candidates for standardization by NIST (2 signature schemes, 5 encryption schemes). At a high level, these can all be interpreted as straightforward instantiations of decades-old paradigms. But when we look under the hood, all of them make design choices which impact their security, efficiency and portability in distinct manners; we will discuss these.[…] -

Improved Blind Side-Channel Analysis by Exploitation of Joint Distributions of Leakages
Speaker : Léo Reynaud
Les attaques side channel classiques nécessitent généralement la connaissance du clair (ou du chiffré) afin de calculer des données internes qui seront comparées à des fuites. Des attaques permettent cependant de s’affranchir de ces connaissances, les attaques par distributions jointes. Ces attaques supposent un attaquant capable d’inverser le modèle de consommation, mais aucune connaissance sur[…] -

When Electromagnetic Signals Reveal Obfuscated Malware: Deep and Machine Learning Use cases
Speaker : Duy-Phuc Pham et Damien Marion
The Internet of Things (IoT) is constituted of devices that are expo-nentially growing in number and in complexity. They use plentiful customized firmware and hardware, ignoring potential security issues, which make them a perfect victim for cybercriminals, especially malware authors.We will describe a new usage of side channel information to identify threats that are targeting the device. Using[…] -

Implémentations sécurisées et évaluation pré-silicium contre les attaques physiques.
Speaker : Sofiane Takarabt
Side-channel attacks remain a permanent threat against embedded systems, thus reliable protections should be implemented and must be minutely evaluated. In this presentation, we study different possible ways to evaluate against such threats. We show how an evaluation can be carried out to validate a security level of a protected hardware implementation. This approach allows us to estimate in[…] -

One Fault Can Go A Long Way
Speaker : Shivam Bhasin
*Abstract:* Fault attacks are considered among critical threat to embedded cryptography. This talk will be divided into in two parts. The first part of the talk will explore application of faults on advanced security primitives. We present persistent fault analysis introduced at CHES 2017 and its capability to bypass state of the art fault countermeasures as well as higher-order masking with one[…] -
