Onysis: A secure European SoC FPGA
Speaker : Adrien GRASSEIN - Nanoxplore
Developed in collaboration with the DGA, the Onysis project introduces a European SoC FPGA designed to embed advanced hardware security features. This presentation will provide an overview of the Onysis architecture, focusing specifically on its native mechanisms to protect critical systems. We will detail the implementation of its integrated security subsystem, covering the secure boot sequence[…]-

Security of Smart Dust: Robust Key Derivation for Single-Chip Systems
Speaker : Sara Faour - Inria
The Smart Dust vision seeks to enable large networks of millimeter-scale wireless sensor nodes that tightly integrate sensing, computation, communication, and power management into a single-chip device. Establishing a robust hardware root of trust for such devices remains challenging, particularly in single, low-cost chip manufacturing processes that lack embedded writable Non-Volatile Memory (NVM[…]-

HDL simulation for Masked Software Verification
Speaker : Quentin Meunier - Sorbonne Univ. Lip6
Masking is a countermeasure against Side-Channel Attacks (SCA) that aims to ensure that intermediate computations in an algorithm have secret-independent distributions through the use of random variables. This theoretically prevents SCAs, as power consumption is directly linked to the values manipulated by the program or hardware device. Designing a masking scheme is often non-trivial, and a[…]-

Étude, caractérisation et détection de verrouillage d'anneaux oscillants utilisés dans les générateurs de nombres aléatoires.
Speaker : Eloise Delolme - LabHC
Les générateurs de nombres aléatoires matériels basés sur des oscillateurs en anneau (RO-TRNGs) exploitent le jitter d’horloge comme source d’aléa afin de produire des séquences de bits aléatoires. Parmi ces architectures, le MURO-TRNG repose sur un modèle stochastique complexe qui suppose notamment l’indépendance des oscillateurs. Toutefois, dans la pratique, les oscillateurs en anneau sont[…]-

Cryptanalysis of full BEANIE
Speaker : Xavier Bonnetain - Inria
BEANIE is a tweakable block cipher recently published at ToSC aiming for memory encryption of microcontroller units. In line with this goal, it handles small plaintexts of only 32 bits and has a low latency. In this paper, we propose the first third-party analysis of the two variants of BEANIE. By carefully leveraging structural properties of the cipher and taking advantage of its distinctive[…]-

MIKE: An efficient and compact NIKE Based on a Commutative Monoidal Action
Speaker : Jonathan Komada Eriksen - COSIC, KU Leuven
Robert recently described a powerful correspondence between certain (Hermitian) modules and (polarized) abelian varieties, which simultaneously generalizes both the class-group action underlying protocols such as CSIDH, and the Deuring correspondence, underlying protocols such as SQIsign. Using this correspondence, he also proposed how to construct a post-quantum NIKE, called MIKE, which, at a[…]-
