| Abstract: | In 2013, Intel developed the SGX[Cor17a] (software guard extensions) instruction set extension, which aims to provide a trusted execution environment in user space. Security of Hardware is considered as a mandatory guarantee. It completely differs from the existed security solution, which depends on firmware and software. However, if users need to use SGX to ensure the security of the program, they need to transfer the source code of the program. Data transmission needs to be realized through a series of user-defined interface functions, which is the only way for data exchange inside and outside the enclave allowed by SGX. When engineers want to use SGX to develop some libraries that were realized, they need to transfer the code with SGX rules or code completely new libraries based on SGX. Instead of reprogramming manually, I describe the new four steps. i) sensitive data annotation, ii) function call analysis, iii) function partition, iv) automatic code transformation, the native code can be transformed into SGX based code. |
