PHOENIX : the first crypto-agile hardware solution for ML-KEM and HQC
Orateur : Antonio RAS
The security of the public-key cryptography protecting today and tomorrow's communication is threatened by the advent of quantum computers. To address this challenge, post-quantum cryptography is employed to devise new quantum-resistant cryptosystems. The National Institute of Standards and Technology (NIST), which led the quantum-safe transition, has already standardized the first lattice KEM[…]-

Advanced techniques for fault injection attacks on integrated circuits
Orateur : Paul Grandamme - Laboratoire Hubert Curien, Université Jean Monnet
The security of integrated circuits is evaluated through the implementation of attacks that exploit their inherent hardware vulnerabilities. Fault injection attacks represent a technique that is commonly employed for this purpose. These techniques permit an attacker to alter the nominal operation of the component in order to obtain confidential information. Firstly, we propose the utilisation of[…]-

Measurement the thermal component of clock jitter used as entropy source by TRNGs
Orateur : Arturo GARAY - STMicroelectronics
Introduction Measuring the thermal component of clock jitter as an entropy source for True Random Number Generators (TRNGs) is compulsory for the security and evaluation of clock-jitter based TRNGs. However, identifying and isolating the local thermal noise component from other noise sources, particularly flicker noise, while performing a precise measurement remains a challenge. Current[…]-

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

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