A Uniquified Virtualization Approach to Hardware Security
Greg Stitt, Robert Karam, Kai Yang, Swarup Bhunia · IEEE Embedded Systems Letters · 2017
Virtualization has well-known security advantages for operating systems and software, but current techniques do not address increasingly important hardware-security concerns. For widely deployed systems (e.g., Internet of Things) and safety-critical systems (e.g., defense and automobiles), protecting against device tampering is critical, but is often unavoidable due to the relative ease of side-channel attacks. In this letter, we present a novel usage of virtualization that limits damage from bitstream tampering to a single instance of a deployed system by employing unique virtual architectures (i.e., overlays) on field-programmable gate arrays.
