Description
libecc is a software library for elliptic curves based cryptography (ECC), with an API supporting signature algorithms specified in the ISO14888-3 standard.
Advanced usages of this library also include the possible implementation of elliptic curve based Diffie-Hellman protocols as well as any algorithm on top of prime fields based elliptic curves (or prime fields, or rings of integers).
The presentation will introduce the rationale behind the development of libecc, as well as its architecture. Compared to other cryptographic libraries providing similar features, the differentiating points are a focus on code simplicity, portability, and auditability (self-contained and pure C99 code); a clean layer separation for all needed mathematical abstractions and operations; and a security over performance motivation (with endeavour to offer decent throughput in addition to moderate RAM and ROM memory footprints).
Though some efforts have been made to have (most of) the core algorithms constant time, turning libecc into a library shielded against side-channel attacks (SCA) is still a work in progress. The choices that have been made to resist against SPA and DPA will be contextualized and discussed.
Finally, concrete examples of libecc integration in both internal and external projects will be examined.

ML-Based Hardware Trojan Detection in AI Accelerators via Power Side-Channel Analysis
Speaker : Yehya NASSER - IMT Atlantique
Our work discusses the security risks associated with outsourcing AI accelerator design due to the threat of hardware Trojans (HTs), a problem traditional testing methods fail to address. We introduce a novel solution based on Power Side-Channel Analysis (PSCA), where we collect and preprocess power traces by segmenting them and extracting features from both time and frequency domains.
