摘要: Embodiments of an invention for secure processing environment measurement and attestation are disclosed. In one embodiment, a processor includes an instruction unit and an execution unit. The instruction unit is to receive a first instruction associated with a build or a rebuild of a secure enclave. The execution unit is to execute the first instruction. Execution of the first instruction, when associated with the build, includes calculation of a first measurement and a second measurement of the secure enclave. Execution of the first instruction, when associated with the rebuild, includes calculation of the second measurement without calculation of the first measurement.
