Ph.D. Candidate in Cyber Security · Kookmin University, Seoul, South Korea
Security research for 5G and 6G mobile networks.
I am a doctoral candidate at Kookmin University in Seoul. My research covers false base station detection, formal verification of 3GPP authentication protocols, and post-quantum cryptography, alongside the extended 5G testbed my experiments run on.

False base station detection in beyond-5G networks
A false base station impersonates legitimate network infrastructure to intercept traffic or track subscribers. Detecting one is hard because genuine attack data is scarce, and the signals that distinguish an attacker from a congested cell are subtle.

An end-to-end 5G testbed for security research
Evaluating new mobile network security mechanisms requires a network that can be modified end to end. Commercial equipment is closed, and the available open-source implementations each cover a single component, stop short of the interfaces most relevant to security research, and are not designed to interoperate across non-3GPP access, non-public networks, and the cryptography beneath them.

Quantum-resilient authentication for 5G and 6G
The authentication protocols securing mobile networks today rest on cryptography that a sufficiently large quantum computer would break. Replacing them is constrained by backward compatibility and by the strict latency budgets of mobile handover.

Open to research collaboration.
I complete my doctorate in 2027 and continue my work at Udayana University in Bali. I welcome joint research on mobile network security and post-quantum cryptography, and collaborations that make use of the 5G testbed.
