Abstract: An IC chip can provide silicon root of trust (RoT) functionality. In described implementations, the IC chip includes a processor, an interconnect, and multiple peripheral devices. These comportable circuit components are designed to facilitate interoperability and consistent, expected communications for security circuitry. Each peripheral device includes an interface that adheres to a common framework for interacting with the processor and with other peripheral devices. The interface includes an interconnect interface coupling the peripheral device to the interconnect and an inter-device interface 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 in accordance with an inter-device scheme of an interface specification.

Abstract: In one general aspect, a method can include receiving, by a computing device, an indication of movement of the computing device, receiving, by the computing device, an input from one of a touchpad, a touch-sensitive surface of a lid portion of the computing device, a trackpad, one or more mouse buttons, and a keyboard during the movement of the computing device, determining, based on the received indication of the movement of the computing device, that the received input is a false input, and ignoring, by the computing device, the received input based on determining that the received input is a false input.
