Fwd: Subject: [ PFIR ] Physical Key Extraction Attacks on PCs Physical Key Extraction Attacks on PCs http://cacm.acm.org/magazines/2016/6/202646-physical-key-extraction-attacks-... Our research thus focuses on two main questions: Can physical side-channel attacks be used to nonintrusively extract secret keys from PCs, despite their complexity and operating speed? And what is the cost of such attacks in time, equipment, expertise, and physical access? Results. We have identified multiple side channels for mounting physical key-extraction attacks on PCs, applicable in various scenarios and offering various trade-offs among attack range, speed, and equipment cost. The following sections explore our findings, as published in several recent articles.
