Trustworthy Hardware Design with Logic Locking

As the designated root of trust, hardware is undoubtedly the most critical layer to security in modern electronic systems. Protecting its integrity throughout the integrated circuit supply chain is of paramount importance. Logic locking has become a prominent tool to safeguard hardware against malicious design modifications. In this work, we introduce a comprehensive logic-locking framework that enables locking schemes for complex hardware designs. We further introduce new concepts in security metrics, locking policies, and attacks. Finally, we showcase the applicability of the framework through MiG-V—the first logic-locked processor available on the market.
