Opening the Doors to <i>Dynamic</i> Camouflaging: Harnessing the Power of Polymorphic Devices

The era of widespread globalization has led to the emergence hardware-centric security threats throughout IC supply chain. Prior defenses like logic locking, layout camouflaging, and split manufacturing have been researched extensively protect against intellectual property (IP) piracy at different stages. In this work, we present dynamic camouflaging as a new technique thwart IP reverse engineering all stages in chain, viz., foundry, test facility, end-user. Toward end, exploit multi-functionality, post-fabrication reconfigurability, run-time polymorphism spin-based devices, specifically magneto-electric spin-orbit (MESO) device. Leveraging these unique properties, is shown be resilient state-of-the-art analytical SAT-based attacks test-data mining attacks. Such reconfigurability not afforded CMOS owing fundamental differences operation. For such MESO-based also anticipate massive savings power, performance, area over other schemes, due energy-efficient electric-field driven reversal MESO Based on thorough experimentation, outline promises securing chain end-to-end along with case study, demonstrating efficacy error-tolerant image processing IP.
