Jinsoo Jang

Associate Professor, SECRET Lab

Computer Science Department

Chungnam National University

II'm an Associate Professor in the Department of Computer Science at Chungnam National University. I received my Ph.D. and M.S. in Information Security from the Graduate School of Information Security (GSIS) at KAIST, and my B.S. from Ajou University. I lead the Secure, Reliable, and Trustworthy Systems Lab (SECRET), which is named after my first paper, titled "SECRET," published at NDSS 2015. My research focuses on securing real-world systems and devices. To achieve this, I leverage commercial security features (e.g., ARM TrustZone, Intel SGX), privileged software layers (e.g., hypervisors), and compiler techniques (e.g., LLVM).
