Реферат: An IC chip can provide silicon root of trust (RoT) functionality. In described implementations, the IC chip includes a processor (202), an interconnect (110), and multiple peripheral devices (250). These comportable circuit components are designed to facilitate interoperability and consistent, expected communications for security circuitry. Each peripheral device includes an interface (302) that adheres to a common framework for interacting with the processor and with other peripheral devices. The interface includes an interconnect interface (304) coupling the peripheral device to the interconnect and an inter- device interface (306) coupling the peripheral device to at least one other peripheral device. The peripheral device is realized based on a peripheral device design code that indicates inter-device signaling (316) in accordance with an inter-device scheme of an interface specification. Manufacturers fabricate the peripheral device, based on the design code, to be physically and logically coupled to another peripheral device in a predictable manner. This fosters more-robust and reliable security circuitry.
