    Generic SCARE: reverse engineering without knowing the algorithm nor the machine

    • April 12, 2024

    • IRMAR - Université de Rennes - Campus Beaulieu Bat. 22, RDC, Rennes - Amphi Lebesgue

    Speaker : Hélène LE BOUDER - IMT Atlantique

    A novel side-channel-based reverse engineering technique is introduced, capable of reconstructing a procedure solely from inputs, outputs, and traces of execution. Beyond generic restrictions, no prior knowledge of the procedure or the chip it operates on is assumed. These restrictions confine the analysis to 8-bit RISC constant-time software implementations. Specifically, the feasibility of[…]

    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.

    Subject Access Request and Proof of Ownership

    • October 25, 2019

    • Inria Center of the University of Rennes - - See the page of each talk for the room.

    Speaker : Cédric Lauradoux (INRIA Rhône-Alpes)

    The GDPR (General Data Protection Regulation) provides rights on our data: access, rectification, objection, etc. However, this regulation is not binding on how we can exercise these rights. Data controllers have therefore deployed various methods to authenticate subject requests. We have analyzed how this authentication process can fail and examined its consequences. Our study shows that a key[…]

    Splitting the Linux Kernel for Fun and Profit

    • December 07, 2018

    • Inria Center of the University of Rennes - - See the page of each talk for the room.

    Speaker : Chris Dalton (HP, Bristol, UK)

    This talk looks at a pragmatic attempt at strengthening the security properties of Linux by introducing a degree of intra-kernel protection into the Linux kernel (supported by CPU Virtualization silicon features). Consider it, if you like, an attempt at retrofitting a ‘micro-kernel’ interface into traditionally monolithic Linux whilst maintaining a single linux code base (yes it’s still Linux), no[…]

    Anonymous Server-Aided Verification

    • March 30, 2018

    • Inria Center of the University of Rennes - - See the page of each talk for the room.

    Speaker : par Elena Pagnin (Chalmers University of Technology, Sweden)

    Server-Aided Verification (SAV) is a method that can be employed to speed up the process of verifying signatures by letting the verifier outsource part of its computation load to a third party. Achieving fast and reliable verification under the presence of an untrusted server is an attractive goal in cloud computing and internet of things scenarios.In this talk I will describe a simple and[…]
