    Laser-Based Attacks Against FPGA Bitstream Encryption

    • June 07, 2019

    • Technische Universität Berlin - Salles Petri/Turing

    Speaker : Heiko Lohrke

    Field programmable gate arrays (FPGAs) use encryption to protect the configuration data or “bitstream” containing the design to be run on the device. This encryption aims at protecting the intellectual property and other secrets contained in the bitstream and preventing e.g. cloning or tampering with an FPGA implementation.This talk will demonstrate how attackers can use failure analysis equipment[…]

    HardBlare, a hardware/software co-design approach for Information Flow Control

    • June 22, 2018

    • Centrale-Supelec - Salles Petri/Turing

    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[…]

    Calibration Done Right: Noiseless Flush+Flush Attacks

    • March 19, 2021

    • DGA-IRISA - Web-Conférence

    Speaker : Guillaume Didier

    Caches leak information through timing measurements and so-called side-channel attacks. Several primitives exist with different requirements and trade-offs. Flush+Flush is a stealthy and fast cache attack primitive that uses the timing of the clflush instruction depending on the presence of a line in the cache. However, the CPU interconnect plays a bigger role than thought in these timings, and[…]

    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[…]

    Rank metric cryptography and its implementations

    • October 08, 2021

    • XLIM – Université de Limoges - Salle Pétri/Turing

    Speaker : Nicolas Aragon

    In 2017, the NIST (National Institute for Standards and Technology) started astandardization process in order to select post-quantum encryption and digital signature schemes. Among the proposed solutions, two rank-metric based encryption schemes were selected for the second round of the standardization process: ROLLOand RQC.This raised questions about both the performance and the security of the[…]

    Side Channel Analysis: Instruction extraction and Information estimation

    • May 06, 2022

    • CEA-LETI; Université de Montpellier, LIRMM - Salle Pétri/Turing

    Speaker : Valence Cristiani

    Side-channel usually aims at extracting cryptographic secrets from electronic devices through their physical leakages. However, these channels can leak other sensitive information. The first part of this talk will present a study of side channel-based disassembling (SCBD) that aims to recover instructions executed by a microcontroller. The main threat represented by SCBD is that it potentially[…]
