Welcome

This is my academic website, where you can find information on my current research. I’m currently a postdoctoral fellow in Prof. Peng Liu's group at the Pennsylvania State University.

Before working as a post-doc at Penn State, I received my BS degree from the University of Science and Technology of China, and my PhD from the University of Chinese Academy of Sciences in 2015. My research interests cover a wide range of system security. My PHD dissertation focuses on hiding critical data such as cryptographic keys in a computing system (appears in IEEE S&P and NDSS). At Penn State, I'm more interested in the security of mobile devices. We developed a system that shields COTS binaries to securely execute on the ARM platform with TrustZone (appears in MobiSys), and a bare-metal malware analysis platform for Android that could restore to a clean-state snapshot in 2.80 seconds (appears in ACSAC). I'm now working on the security of IoT systems running on low-end microcontrollers. We disclosed a vulnerability that appears in many telematics devices (appears in SenSys). The purpose of this research is to provide a comprehensive protection for devices of several bucks.
