摘要： Disclosed in some examples are devices, methods, and machine-readable mediums for reliable control of IR LEDs. In some examples, a microcontroller running firmware controls whether the LED is activated or not by use of a disable signal. The microcontroller enables or disables the operation of the LED based upon a user's proximity to the LED, a watchdog timer, and a confirmation that only trusted software is executing.

摘要： In one embodiment, a processor has at least one core to execute instructions, a security engine coupled to the at least one core, a first storage to store a first immutable key associated with a vendor of the processor, and a second storage to store a second immutable key associated with an original equipment manufacturer (OEM) of the system. A first portion of firmware is to be verified based at least in part on the first immutable key and a second portion of firmware is to be verified based at least in part on the second immutable key, the first portion of firmware associated with the vendor and the second portion of firmware associated with the OEM. Other embodiments are described and claimed.
