Welcome to Secure Systems Lab (SSLab) in the Department of Computer Science and Engineering in College of Computing at Yonsei University. We are a group of people who are genuinely interested in improving the security of modern computer systems, and we are currently deeply invested in LLM and agentic systems. Our research spans both ends of this challenge: hardening these systems against new threats and harnessing them to tackle long-standing security and privacy problems, drawing on a combination of systems and machine learning techniques.
To Prospective Students
We are always looking for motivated students who enjoy building, breaking, or securing software and AI systems.
If you are interested in research at any level (undergrad, M.S., Ph.D., or Post-Doc) in software and AI system security, please reach out to Prof. Dokyung Song at dokyungs@yonsei.ac.kr.
Research Areas
Securing LLM & Agentic Systems against Emerging Threats
Building Agentic Systems that Discover Software Vulnerabilities
Building Agentic Systems for Binary Reverse Engineering
