More Information
Summary:System and method for creating and managing trusted execution environments (TEEs) using different underlying hardware TEE mechanisms use a virtual secure enclave device which runs in a virtualized environment in a computer system. The device enables an enclave command transmitted to the virtual secure enclave device to be retrieved and parsed to extract an enclave operation to be executed. A TEE backend module is used to interact with a particular hardware TEE mechanism among those available in the computer system. The module ensures the enclave operation for the software process is executed by the particular hardware TEE mechanism, or the TEE scheme based on a particular hardware TEE mechanism.
