(54)	Establishing physical locality between secure execution environments

(57) Embodiments of an invention for establishing physical locality between secure execution environments are disclosed. In one embodiment, a processor includes a storage location and an execution core. The storage location is to store a locality nonce. The execution core is to execute a first instruction to create a secure execution environment. The execution core is also to execute, from within the secure execution environment, a second instruction to read the locality nonce from the storage location.
