Securing Hardware via Dynamic Obfuscation Utilizing Reconfigurable Interconnect and Logic Blocks
Hosted in Virtual Platform
Hardware Security: Primitives, Architecture, Design & Test
DescriptionMany of the existing security works have targeted towards resolving a single vulnerability while neglecting the possibility of other threats, which motivates us to propose a novel approach for securing the hardware IPs using emerging spin-based devices. Our proposed obfuscation approach uses Reconfigurable Logic and Routing to provide flexibility and resiliency against the state-of-the-art SAT-based and power side-channel attacks while incurring small overhead. The proposed obfuscation also obfuscates the responses of the Oracle circuit, resembling a defense-in-depth approach. The empirical evaluation of the ISCAS benchmark shows that resiliency comes with reduced overhead while providing resiliency to various attacks.
