SGX Project Template

This template is based on the hello-enclave app hello-enclave.

Prerequirements

• To install Intel SGX, clone the project and follow the steps from official repository.
• SGX requires some environment variables, need to source the environment before compiling an SGX project. source ${sgx-sdk-install-path}/environment I suggest adding the command to the startup script of your shell.
• Now you are ready to compile this project.

Compile - Execution

1. make to compile the project.
2. The default make rule creates app file that can be executed.

Description

• Project is compiled in Simulation Mode. There is no hardware requirement.
• The untrusted domain is App/App.cpp
• The trusted domain (Enclave) is Enclave/Enclave.app
• The Enclave Definition (EDL) file is Enclave/Enclave.edl
• For basic projects, modifying App.cpp, Enclave.cpp and Enclave.edl file is enough.
• Enclave.h can be used for defining user defined types etc.

Additional Information

• The Enclave.h in the root folder is used when a user defined type such as typedef and struct needs to be defined for edger8r. For that the header file gets included in the EDL file.
• For SGX, the untrusted domain needs to initalize an enclave. That is handled by the small helper App/sgx_utils library.
• Edger8r generally emits an error if there is a syntactic or semantic problem with the EDL file.
