Abstract
Examples include an apparatus which accesses secure pages in a trust domain using secure lookups in first and second sets of page tables. For example, one embodiment of the processor comprises: a decoder to decode a plurality of instructions including instructions related to a trusted domain; execution circuitry to execute a first one or more of the instructions to establish a first trusted domain using a first trusted domain key, the trusted domain key to be used to encrypt memory pages within the first trusted domain; and the execution circuitry to execute a second one or more of the instructions to associate a first process address space identifier (PASID) with the first trusted domain, the first PASID to uniquely identify a first execution context associated with the first trusted domain.
