A computing platform implements one or more secure enclaves including a first provisioning enclave to interface with a first provisioning service to obtain a first attestation key from the first provisioning service, a second provisioning enclave to interface with a different, second provisioning service to obtain a second attestation key from the second provisioning service, and a provisioning certification enclave to sign first data from the first provisioning enclave and second data from the second provisioning enclave using a hardware-based provisioning attestation key. The signed first data is used by the first provisioning enclave to authenticate to the first provisioning service to obtain the first attestation key and the signed second data is used by the second provisioning enclave to authenticate to the second provisioning service to obtain the second attestation key.
