About me

I am a Ph.D. candidate in the Department of Computer Science and Engineeing at Seoul National University.My advisor is Yongsoo Song and my research interests are in Cryptography, Privacy and Security. In these days, I’m especially interested in various cryptographic primitives and applications such as homomorphic encryption, multi-party computation, zero-knowledge proof, and digital signature.

Before studying in Seoul National University, I studied and obtained Bachelor’s degree in Sungkyunkwan University, from 2014. During the course, my major was mathematics and computer science. I worked as an undergraduate research student with Hyoungshick Kim, from 2019 to 2020. I also did an intership in CSIRO Data 61, from September to December 2019.

I’m especially interested in constructing efficient threshold cryptographic primitives such as homomorphic encryption or digital signature and designing practical multi-party computation protocols. More details about my research interests are following:

• Improve the performance of Homomorphic Encryption (HE) schemes.
• Design a modern cryptographic technology with high usability and flexibility of and use it to enhance the efficiency.
• Construct several cryptographic primitives (HE, MPC, signature) for multiple parties.
• Applying cryptographic primitives to various applications such as machine learning
