Abstract
The public enclave key of each enclave in an enclave pool may be registered in an enclave pool registry, and the registry updated each time there is an enclave pool membership change. A shared enclave pool key may be derived from the public enclave key of each enclave of the enclave pool. The shared enclave pool key may be stored, in a shared key ledger, as a first version of the shared enclave key, and an updated version of the shared key may be generated and stored as another version each time there is an enclave pool membership change. The output of a cryptlet that executed in multiple enclaves may be signed with the enclave private key of each enclave in which the cryptlet executed. Each enclave signature may be compared against each version of the of the shared enclave pool key in the shared key ledger.
