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 crypto primitives for secure blockchains and/or deep learning such as zero-knowledge proofs and bio authentication.


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 blockchain research. Not necessary but preferred to have experience in the area of developing crypto libraries and/or blockchain. Programming skills such as Rust and C++ will be more favorable.

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

    • 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.


2020. Jan. Program Committee

In this year, I will serve as a program committee member of several international conferences, ASIACRYPT, ProvSec, ICISC, IWSEC, and APKC.

2019. Dec. A paper is accepted for publication in Information Sciences.

Title: Public Key Encryption with Equality Test in the Standard Model

This is the first standard model construction for public key encryption with equality test.

2019. Sep. A paper is accepted for publication in Information Sciences.

Title: Efficient Digital Signatures from RSA without Random Oracles

The proposed scheme is one of the most efficient digital signature schemes, at least current best one in the category of (non-strong) RSA-based standard model hash-and-sign signature schemes.
