    Vers une meilleure compréhension de l’apprentissage profond appliqué aux attaques par observation

    • January 10, 2020

    • CEA - Salle Métivier

    Speaker : Loïc Masure

    Les attaques par observation (SCA) exploitent les failles d’une primitive cryptographique embarquée sur un composant (type carte à puce, IoT, …), en mesurant des grandeurs physiques qui dépendent indirectement de la valeur de la clé secrète. C’est pourquoi il est primordial pour les développeurs de proposer des contre-mesures adaptées et d’évaluer leur efficacité face à un attaquant potentiel.Au[…]

    Schindler-Itoh/Wiemers revisited: recovering full RSA/ECC private key from noisy side-channel observations

    • September 28, 2018

    • NinjaLab - Salle Métivier

    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.[…]

    Code-based postquantum cryptography : candidates to standardization

    • April 23, 2021

    • INRIA - Web-Conférence

    Speaker : Nicolas Sendrier

    At the third round of the NIST standardization process, three candidates remain with a security based on error correcting codes, all are key exchange mechanisms. We will explore them according to their security assumptions and properties. Among them, we find an historical scheme (Classic McEliece), as well as schemes using sparse and quasi-cyclic matrices (BIKE and HQC). We will examine pros and[…]

    Improved Blind Side-Channel Analysis by Exploitation of Joint Distributions of Leakages

    • April 05, 2019

    • Faculté des sciences de Limoges - Salles Pétri/Turing

    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[…]

    Bridging Deep Learning and Classical Profiled Side-Channel Attacks

    • April 08, 2022

    • Thales ITSEF, Toulouse - Salle Pétri/Turing

    Speaker : Gabriel Zaid

    Over the recent years, the cryptanalysis community leveraged the potential of research on Deep Learning to enhance attacks. In particular, several studies have recently highlighted the benefits of Deep Learning based Side-Channel Attacks (DLSCA) to target real-world cryptographic implementations. While this new research area on applied cryptography provides impressive result to recover a secret[…]

    One Fault Can Go A Long Way

    • November 15, 2019

    • Nanyang Technological University - Métivier

    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[…]
