    libecc: a flexible open-source ECC library for embedded devices

    • February 14, 2020

    • ANSSI - Salle Pétri/Turing

    Speaker : Ryad Benadjila et Arnaud Ebalard

    libecc is a software library for elliptic curves based cryptography (ECC), with an API supporting signature algorithms specified in the ISO14888-3 standard.Advanced usages of this library also include the possible implementation of elliptic curve based Diffie-Hellman protocols as well as any algorithm on top of prime fields based elliptic curves (or prime fields, or rings of integers).The[…]

    Étude des cellules oscillantes pour la génération d’aléa dans les circuits électroniques numériques

    • December 14, 2018

    • Univ Lyon, UJM-Saint-Etienne, CNRS, Laboratoire Hubert Curien - Salle Métivier

    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

    • April 23, 2021

    • PQShield – United Kingdom - Web-Conférence

    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

    • May 10, 2019

    • INRIA - Salles Petri/Turing

    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[…]

    Implémentations sécurisées et évaluation pré-silicium contre les attaques physiques.

    • February 04, 2022

    • Secure-IC - Web-conférence

    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[…]

    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[…]
