    Post-quantum Group-based Cryptography

    • 10 janvier 2025 (13:45 - 14:45)

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

    Orateur : Delaram Kahrobaei - The City University of New York

    Group-based cryptography is a relatively new family in post-quantum cryptography, with high potential. I will give a general survey of the status of post-quantum group-based cryptography and present some recent results.In the second part of my talk, I speak about Post-quantum hash functions using special linear groups. This hash function is a generalization of Tillich-Zemor hash function as well[…]

    I know what your compiler did: Optimization Effects on Power Side-Channel Leakage for RISC-V

    • 24 janvier 2025 (11:00 - 12:00)

    • Inria Center of the University of Rennes - Espace de conférences

    Orateur : Ileana Buhan - Radboud University Nijmegen

    With the growing prevalence of software-based cryptographic implementations in high-level languages, understanding the role of architectural and micro-architectural components in side-channel security is critical. The role of compilers in case of software implementations towards contribution to side-channel leaks is not investigated. While timing-based side-channel leakage due to compiler effects[…]

    Hardware Trojan Horses and Microarchitectural Side-Channel Attacks: Detection and Mitigation via Hardware-based Methodologies

    • 24 janvier 2025 (10:00 - 11:00)

    • Inria Center of the University of Rennes - Espace de conférences

    Orateur : Alessandro PALUMBO - CentraleSupélec, IRISA, Inria

    Hardware Trojan Horses that are software-exploitable can be inserted into microprocessors, allowing attackers to run unauthorized code or escalate privileges. Additionally, it has been demonstrated that attackers could observe certain microprocessor features - seemingly unrelated to the program's execution - to exfiltrate secrets or private data. So, even devices produced in secure foundries could[…]

    Covert Communication Channels Based On Hardware Trojans: Open-Source Dataset and AI-Based Detection

    • 28 février 2025 (10:00 - 11:00)

    • Inria Center of the University of Rennes - - IRISA - Salle Aurigny (D165)

    Orateur : Alan Díaz Rizo - Sorbonne Université Lip6

    The threat of Hardware Trojan-based Covert Channels (HT-CCs) presents a significant challenge to the security of wireless communications. In this work, we generate in hardware and make open-source a dataset for various HT-CC scenarios. The dataset represents transmissions from a HT-infected RF transceiver hiding a CC that leaks information. It encompasses a wide range of signal impairments, noise[…]
