Abstract:
In one embodiment, a processor can enforce a blacklist and validate, according to a multi-phase lockstep integrity protocol, a device coupled to the processor. Such enforcement may prevent the device from accessing one or more resources of a system prior to the validation. The blacklist may include a list of devices that have not been validated according to the multi-phase lockstep integrity protocol. Other embodiments are described and claimed.
