About me

I am a PhD candidate majoring in cryptography at Department of Mathematical Sciences, Seoul National University (SNU), Republic of Korea. My advisor is Prof. Jung Hee Cheon. I am interested in analyzing the security of various cryptographic primitives and homomorphic encryption. Currently my research topics are on statistical analysis for cryptographic primitives and privacy-preserving machine learning.
