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[…] -

Post-Quantum Cryptography Hardware: Monolithic Implementations vs. Hardware-Software Co-Design
Speaker : Markku-Juhani Saarinen
At PQShield, we’ve developed dedicated coprocessor(s) for lattice schemes, hash-based signatures, and code-based cryptography. These cryptographic modules are commercial rather than academic and designed to meet customer specifications such as a specific performance profile or Common Criteria and FIPS security certification requirements.Hardware implementations of legacy RSA and Elliptic Curve[…] -

Do Not Trust Modern System-on-Chips - Electromagnetic fault injection against a System-on-Chip
Speaker : Ronan Lashermes
Electromagnetic fault injection (EMFI) is a well known technique to disturb the behavior of a chip and weaken its security. These attacks are still mostly done on simple microcontrollers since the fault effects is relatively simple and understood.Unlocking EMFI on modern System-on-Chips (SoCs), the fast and complex chips ubiquitous today, requires to understand the impact of the faults. In this[…] -

Vers une meilleure compréhension de l’apprentissage profond appliqué aux attaques par observation
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[…] -

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[…] -

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.[…] -
