Hardware Trojans (HTs) have become a major concern in modern IC industry, especially with the fast growth in IC outsourcing. HT detection and diagnosis are challenging due to the huge number of gates in modern IC designs and the high cost of testing. The authors propose a scalable and efficient HT detection and diagnosis scheme based on segmentation and consistency analysis of the gate-level properties. Furthermore, they develop a HT masking approach that prevents the HTs from functioning using selective device aging. They evaluate their HT detection and diagnosis schemes on a set of ISCAS and ITC benchmarks.
