True Random Number Generators enabled hardware security
Speaker : Bohan Yang
True randomness is all about unpredictability, which can neither be qualified nor quantified by examining statistics of a sequence of digits. Unpredictability is a property of random phenomena, which is measured in bits of information entropy. Application of randomness spans from art to numerical computing and system security. Random numbers enable various cryptographic algorithms, protocols and[…] -
Une approche pour l’accélération matérielle pour le chiffrement homomorphe
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.[…] -
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[…] -
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.[…] -
Security of Hardware/Software Interfaces : Research Chair of the Cybersecurity Research Cluster
Speaker : Guillaume Hiet
We proposed to host a thematic semester on attacks based on the interaction between software and hardware. The goal would be to host one workshop, one summer school for young researchers, as well as multiple seminars and longer stays for researchers, spanning September 2019 to March or April 2020. This thematic semester will be funded by the DGA in the context of the Cybersecurity Research Cluster[…] -
HardBlare, a hardware/software co-design approach for Information Flow Control
Speaker : Guillaume Hiet – Pascal Cotret
One way to increase the security level of computer systems is to rely on both software and hardware mechanisms. In this context, the HardBlare project proposes a software hardware co-design methodology to ensure that security properties are preserved all along the execution of the system but also during file storage. The HardBlare project is a multidisciplinary project between CentraleSupélec IETR[…]
