Explore advanced micro-architectural security research in this conference session from CHES 2025, chaired by Jan Philipp Thoma. Delve into cutting-edge topics related to hardware security vulnerabilities, side-channel attacks, and defensive mechanisms at the micro-architectural level. Learn about the latest research findings and methodologies in securing computer systems against attacks that exploit low-level hardware features such as caches, branch predictors, and speculative execution units. Gain insights into emerging threats and countermeasures that address security challenges in modern processor architectures, with presentations covering both theoretical foundations and practical implementations in the field of cryptographic hardware and embedded systems security.
