Welcome!
I’m Seongmin Cho who received my B.S. in Electrical Engineering at Hanyang University ERICA @Ansan, and my Ph.D. in cyber-security in Embedded Security and Privacy Laboratory (advisor: Seung-Hyun Seo) at Hanyang University.
I'm currently working as a researcher at the Cyber Warfare Technology Research Center of the Electronics and Telecommunications Research Institute (ETRI).
I am interested in cyber warfare security, Post-Quantum Cryptography (PQC), quantum cryptography, and quantum cryptanalysis. Currently, I am focusing on analyzing the security of PQCs using quantum algorithms.
In my spare time, I enjoy taking pictures, playing football, traveling by driving, and watching Premier League (huge fan of Arsenal FC) and KBO League (fan of Samsung Lions).
