The Intel Software Guard Extensions (SGX) is a new technology introduced to make secure and trustworthy computing in a hostile environment practical. However, SGX is merely just a set of instructions. Its software support that includes the OS support, toolchain and libraries, is currently developed in a closed manner, limiting its impact only within the boundary of big companies such as Intel and Microsoft. Meanwhile, SGX does not automatically secure everything and it still faces various attacks such as controlled-side channel and enclave memory corruption.This research investigates how to enable application developers to securely use the SGX instructions, with an open source software support including a toolchain, programming abstractions (e.g., library), and operating system support (e.g., kernel modules). In addition, this research systematically explores the systems and software defenses necessary to secure the SGX programs from the enclave itself and defeat the malicious use of SGX from the underlying OS.

英特尔Software Guard Extensions（SGX）是一项新技术，旨在使恶意环境中的安全可靠计算成为现实。然而，SGX仅仅是一套指令。 它的软件支持，包括操作系统支持，工具链和库，目前是以封闭的方式开发的，其影响仅限于英特尔和微软等大公司的范围内。同时，SGX并不能自动保护所有内容，仍然面临着各种攻击，如受控端通道和飞地内存损坏。本研究探讨了如何使应用程序开发人员能够安全地使用SGX指令，并提供开源软件支持，包括工具链，编程抽象（例如，库）和操作系统支持（例如，内核模块）。此外，本研究还系统地探讨了保护SGX程序免受安全区本身影响并击败恶意使用SGX的底层操作系统所需的系统和软件防御。
