Abstract

A processor to support platform migration of secure enclaves is disclosed. In one embodiment, the processor includes a memory controller unit to access secure enclaves and a processor core coupled to the memory controller unit. The processor core to identify a control structure associated with a secure enclave. The control structure comprises a plurality of data slots and keys associated with a first platform comprising the memory controller unit and the processor core. A version of data from the secure enclave is associated with the plurality of data slots. Migratable keys are generated as a replacement for the keys associated with the control structure. The migratable keys control access to the secure enclave. Thereafter, the control structure is migrated to a second platform to enable access to the secure enclave on the second platform.
