This application discloses a computing system implementing tools and mechanisms that can incorporate an optical physical uncloneable function (PUF) device in a circuit design. The optical physical uncloneable function device can generate at least a portion of a key. The tools and mechanisms can interconnect the optical physical uncloneable function device with a security control device in the circuit design, wherein the security control device is configured to initiate a security action when the key matches an expected key in the security controller.
