The paper explores the relationship between logic locking and hardware Trojans (HWT), two fields in hardware security that have been mostly developed independently. It introduces a new type of HWT, called Trojans based on Logic Locking (TroLL), which can evade state-of-the-art ATPG-based HWT detection techniques. The authors propose customization of existing ATPG-based HWT detection approaches and adapting SAT-based attacks on logic locking to HWT detection to detect TroLL. However, they concede that these methods offer limited improvement and their efficacy diminishes as TroLL’s triggers become longer, highlighting the need for a scalable HWT detection approach for TroLL.
