Abstract: Techniques are disclosed relating to the secure communication of devices. In one embodiment, a first device is configured to perform a pairing operation with a second device to establish a secure communication link between the first device and the second device. The pairing operation includes receiving firmware from the second device to be executed by the first device during communication over the secure communication link, and in response to a successful verification of the firmware, establishing a shared encryption key to be used by the first and second devices during the communication. In some embodiments, the pairing operation includes receiving a digital signature created from a hash value of the firmware and a public key of the second device, and verifying the firmware by extracting the hash value from the digital signature and comparing the extracted hash value with a hash value of the received firmware.

Abstract: Techniques are disclosed in which a secure circuit controls a gating circuit to enable or disable other circuity of a device (e.g., one or more input sensors). For example, the gating circuit may be a power gating circuit and the secure circuit may be configured to disable power to an input sensor in certain situations. As another example, the gating circuit may be a clock gating circuit and the secure circuit may be configured to disable the clock to an input sensor. As yet another example, the gating circuit may be configured to gate a control bus and the secure circuit may be configured to disable control signals to an input sensor. In some embodiments, hardware resources included in or controlled by the secure circuit are not accessible by other elements of the device, other than by sending requests to a predetermined set of memory locations (e.g., a secure mailbox).
