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.

(Thesis title: New Frameworks for Privacy-Preserving Set Operations. Proposed new frameworks for efficient privacy-preserving set intersection and set union protocols and also proposed a new round-efficient zero-knowledge proof protocol to guarantee security of privacy-preserving protocols against malicious adversaries.)

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


2020. Jan. Program Committee

In this year, I will serve as a program committee member of several international conferences, ASIACRYPT 2020, ProvSec 2020, IWSEC 2020, and APKC 2020.

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.
