    Modélisation statistique et sécurité des générateurs d'aléa pour la cryptographie

    • April 08, 2023 (11:00 - 12:00)

    • À l'IRISA, campus de Beaulieu, Rennes

    Speaker : David Lubicz - DGA, IRMAR

    Dans cet exposé on essaie d'expliquer ce que l'on entend pas méthodes statistiques et on donne des exemples concrets d'application dans la cybersécurité.

    True Random Number Generators enabled hardware security

    • March 29, 2019

    • Hardware Security and Cryptographic Processor Lab, Institute of Microelectronics, Tsinghua University, China - Métivier

    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[…]

    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[…]

    Security challenges and opportunities in emerging device technologies: a case study on flexible electronics

    • May 06, 2022

    • Leiden University, The Netherlands?, and KU Leuven, Belgium - Salle Pétri/Turing

    Speaker : Nele Mentens - KU Leuven, Belgium

    While traditional chips in bulk silicon technology are widely used for reliable and highly ef?cient systems, there are applications that call for devices in other technologies. On the one hand, novel device technologies need to be re-evaluated with respect to potential threats and attacks, and how these can be faced with existing and novel security solutions and methods. On the other hand,[…]

    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[…]
