    SideLine and the advent of software-induced hardware attacks

    • March 19, 2021

    • Mines Saint-Etienne – Thales - Web-Conférence

    Speaker : Joseph Gravellier

    In this talk, we will discuss software-induced hardware attacks and their impact for IoT, cloud and mobile security. More specifically, I will introduce SideLine, a new power side-channel attack vector that can be triggered remotely to infer cryptographic secrets. SideLine is based on the intentional misuse of delay-lines components embedded in SoCs that use external memory. I will explain how we[…]

    Une approche pour l’accélération matérielle pour le chiffrement homomorphe

    • December 14, 2018

    • CEA List

    Speaker : Joël Cathebras

    Le chiffrement homomorphe est un outil cryptographique permettant la manipulation de données en aveugle. Son utilisation généralisée permettrait de proposer des solutions de calcul déporté impliquant des données confidentielles, par exemple des données génomiques pour la médecine personnalisée. Cependant, le chiffrement homomorphe doit faire face à de grandes complexités mémoires et calculatoires.[…]

    Unique CAD-compatible SCA-security mechanisms, externally amplified coupling (EAC) attacks and (some) connection

    • June 25, 2021

    • Bar-Ilan University (BIU) - Web-Conférence

    Speaker : Itamar Levi

    In this seminar I will first discuss unique computer aided design (CAD) compatible SCA security mechanisms. I will present an approach which can significantly increase the physical security-level of a design, be implemented with conventional design-tools and which does not require any special technological-support. The method consists with a correct by-design utilization of power-management[…]

    Automated software protection for the masses against side-channel attacks

    • May 10, 2019

    • Univ Grenoble Alpes, CEA, List - Salles Petri/Turing

    Speaker : Nicolas Belleville

    This presentation will present an approach and a tool that answer the need for effective, generic, and easily applicable protections against side-channel attacks. The protection mechanism is based on code polymorphism, so that the observable behaviour of the protected component is variable and unpredictable to the attacker. Our approach combines lightweight specialized runtime code generation with[…]

    Masked Proofs and Their Physical Assumptions

    • April 20, 2018

    • Radboud Univeriteit, Nijmegen - Salles Petri/Turing

    Speaker : Vincent Grosso

    Les attaques par canaux auxiliaires sont des menaces majeures contre les mises en uvre cryptographiques. Pour contrer ces attaques, le masquage est une contre-mesure populaire. Un de ces principaux avantages est de pouvoir prouver la sécurité apportée par cette contre-mesure. Ces preuves se basent sur un certain nombre d’hypothèses sur le matériel qui met en uvre le masquage. Dans cette[…]

    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[…]
