5G Core Network, Guided Fuzzing Test, Control Plane Analysis

I am a Master’s student in System Security Lab at Korea Advanced Institute of Science and Technology (KAIST), advised by Professor Yongdae Kim. My research interests are: 1) to implement the testing framework for inspecting new infrastructure like 5G and other network architectures 2) to analyze the infrastructure in network architectures 3) to find and exploit software and hardware vulnerabilities in cellular networks. Especially, I’m putting my effort into analyzing 5G core network structure and security.
