Mutually Distrusting Enclaves

A method (400) for accessing one or more service processes (222) of service (250) includes executing at least one service enclave (220) and executing an enclave sandbox (200) that wraps the at least one service enclave. The at least one service enclave provides an interface to the one or more service processes. The enclave sandbox is configured to establish an encrypted communication tunnel (210) to the at least one service enclave interfacing with the one or more service processes, and communicate program calls (302) to/from the one or more service processes as encrypted communications through the encrypted communication tunnel.
