Abstract
An application such as a virtual machine are executed securely using a software-based, full-system emulator within a hardware-protected enclave, such as an SGX enclave. The emulator may thereby be secure even against a malicious underlying host operating system. In some cases, paging is used to allow even a large application may run within a small enclave using paging. Where the application itself uses enclaves, these guest enclaves may themselves be emulated within an emulator enclave such that the guest enclave(s) are nested as sibling enclaves by the emulator.
