The macro-threats of microarchitectures

,
Processor vulnerabilities are no longer limited to the microarchitecural flaws identified in recent years. They now extend to different contexts and directly affect our digital uses. Faced with these increasingly widespread threats, research in security is mobilizing and multiplying approaches to better understand and address them. Maria Mushtaq, researcher at Télécom Paris and organizer of the MICSEC Winter School, sheds light on these developments and the challenges of a field in full transformation.
