Automated software protection for the masses against side-channel attacks
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
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
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
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[…] -
