👑 About Me

I am currently a Ph.D. student at the School of Cyber Engineering, Xidian University, supervised by Prof. Junwei Zhang. I received my B.S. degree in Information Security from the School of Computer Science and Technology, China University of Mining and Technology, in 2023.

My current research interests focus on AI security, including jailbreak attacks, and the security analysis of retrieval-augmented generation (RAG) systems and agents. Previously, I was also deeply interested in privacy-preserving computation, involving techniques such as secure multi-party computation (MPC) and privacy-preserving machine learning (PPML).

I am currently focused on content generation and security mechanisms in large language models. If you are seeking any form of academic cooperation, please feel free to email me at li.cy@stu.xidian.edu.cn.
