# CCS'17 Tutorial

During CCS 2017, **Taesoo Kim** (Georgia Tech), **Zhiqiang Lin** (UT Dallas) and **Chia-Che Tsai** (Stony Brook University / UC Berkeley) together gave an overall tutorial on Intel SGX technology. The tutorial's contents are well organized and presented by SGX experts in the academia. We believe that this tutorial serves as a perfect entry point to understand the background of SGX technology.

This tutorial consists of three parts, including:

1. SGX 101: introduction, performance, and applications
2. SGX shielding framework and development tools
3. SGX Security Issues

**Presentation slides and demo videos are available** [**here**](https://github.com/sslab-gatech/sgx-tutorial-ccs17)**.**

In this tutorial, **Zhiqiang Lin** first introduced the basic concepts of Intel SGX, its development workflows, potential applications and performance characteristics. Then, **Chia-Che Tsai** introduced various ways to quickly start writing SGX applications, specifically by utilizing library OSes or thin shielding layers; he explained the pros and cons of each approach in terms of security and usability. Last but not least, **Taesoo Kim** explained known security concerns, including cache/branch side-channel attacks and memory safety issues, and corresponding defenses with various working demos.
