I am leading Cryptology & Algorithm Laboratory at Hanyang University. Prior to joining Hanyang university, I was with Myongji university for 5 years and National Institute of Information and Communications Technology (NICT) for about 2 years. Before that, I finished my ph.d. degree at Seoul National University in Feb. 2011.

I'm interested in all aspects in cryptography, computational number theory, and information security.

Recently, I'm very interested in computational algorithms, cryptology, and their applications to deep learning and blockchain.


Now Cryptology & Algorithm Laboratory is hiring highly motivated (under)graduate students from computer science, computer engineering, and mathematics or other related majors.

There are PhD/MS position openings for zero-knowledge proof and deep learning based biometric authentication.

  • There are three departments at Hanyang University that you can join us.

    • Mathematics(수학과)/College of Natural Science

    • Information Security(정보보안학과)/College of Engineering

    • Blockchain Computing and Cryptoeconomics(블록체인융합학과)/College of Engineering

Please contact me via email given the above if you are interested in joining Cryptology & Algorithm Laboratory.
