Hi! I’m Yilin Li, also known as OneZ3r0. I’m an undergraduate student from School of Cyberspace Security, Beijing University of Posts and Telecommunications. I’m currently doing a research internship in Prof. Jianjun Chen’s group at the Network and Information Security Lab (NISL), Tsinghua University.

My research interests lie in protocol and web security, with a focus on security issues arising from protocol design and underlying mechanisms. Currently, I am studying HTTP/3, QUIC, and content delivery networks (CDNs).

Outside of academic research, I previously competed in Capture the Flag(CTF) with Dubhe, focusing on web security challenges.
