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[…] -

Schindler-Itoh/Wiemers revisited: recovering full RSA/ECC private key from noisy side-channel observations
Speaker : Victor Lomné et Thomas Roche
Side-channel attacks on public-key cryptography (i.e. modular exponentiation for RSA or scalar multiplication for ECC) often boils down to distinguishing the 0s from the 1s in the binary representation of the secret exponent (resp. secret scalar).When state-of-the-art countermeasures are implemented, this detection must be errorless: thanks to masking techniques, erroneous masked exponents (resp.[…] -

Rank metric cryptography and its implementations
Speaker : Nicolas Aragon
In 2017, the NIST (National Institute for Standards and Technology) started astandardization process in order to select post-quantum encryption and digital signature schemes. Among the proposed solutions, two rank-metric based encryption schemes were selected for the second round of the standardization process: ROLLOand RQC.This raised questions about both the performance and the security of the[…] -
