ObfusGEM is a comprehensive logic locking simulator designed to evaluate the supply-chain security of locked processor models. It implements an error injection framework inspired by the architectural error resilience community to “close the loop” between module-level logic locking or hardware security techniques and their application and architecture-level impact. We provide a library of existing hardware security techniques and configurations along with a simulation framework in hopes of providing a tool enabling the design and evaluation of hardware security configurations for specific processor architectures or devices.
