Hi there 👋, this is Mingyi Chen.

I’m a fourth-year Ph.D. candidate in the Department of Computer Science, University of California, Irvine. Before that, I received my bachelor’s degree from Sichuan University and master’s degree from University of Chinese Academy of Sciences.

I’m now advised by Prof. Ardalan Amiri Sani and working on trusted computing problems.

Minimizing a Smartphone’s TCB for Security-Critical Programs with Exclusively-Used, Physically-Isolated, Statically-Partitioned Hardware

Zhihao Yao, Seyed Mohammadjavad Seyed Talebi, Mingyi Chen, Ardalan Amiri Sani, Thomas Anderson

Project

• We present a split-trust hardware design composed of statically-partitioned, physically-isolated trust domains. We introduce a few simple, formally-verified hardware components to enable a program to gain provably exclusive and simultaneous access to both computation and I/O on a temporary basis. To manage this hardware, we present OctopOS, an OS composed of mutually distrustful subsystems. We present a prototype of this machine (hardware and OS) on a CPU-FPGA board and show that it incurs a small hardware cost compared to modern smartphone SoCs.
