Character Reassignment for Hardware Trojan Detection

Abstract

With the current business model and increasing complexity of hardware designs, third-party Intellectual Properties (IPs) are prevalently incorporated into first-party designs. The use of third-party IPs increases security concerns related to hardware Trojans inserted by attackers. Previous work on Golden Reference Matching focuses on matching with all entries within a single Golden Reference Library (GRL) containing whitelisted and blacklisted functionalities. This paper presents two new Golden Reference Libraries, Champion GRL and Functionality GRL, which were introduced along with coarse- grained and fine-grained asset reassignment to soft IPs and GRL entries in order to improve matching accuracy while simultaneously saving computational resources.
