Abstract
A protected machine. The machine includes an enclave. An enclave includes a protected area of an application address space for which access is prevented for any application code not resident in the enclave itself, except that keys can be provided by one or more management enclaves into the enclave. The machine further includes a management enclave coupled to the enclave. The management enclave is configured to provide a key to the enclave. The management enclave is a protected area of an application address space for which access is prevented for any application code not resident in the management enclave itself.
