DescriptionLogic locking protects integrated circuits (IC) against intellectual property (IP) theft, IC overbuilding, and hardware Trojan insertion. Prior locking schemes operate after logic synthesis and cannot protect the semantic information embedded into the logic. Register-transfer level (RTL) locking techniques can protect the sensitive IP semantics and are EDA tool-chain agnostic, allowing seamless integration into arbitrary design flows. State-of-the-art RTL locking protects against the untrusted foundry assuming they have no working chip (oracle). We propose to fortify RTL locking to protect against all untrusted entities in the supply chain, viz., foundry (oracle-less attacks), test facility, and end-users (oracle-guided attacks).
