. He is one of the inventors of braid cryptography, one of group-based cryptography, and approximate homomorphic encryption HEAAN. As one of co-inventors of approximate homomorphic encryption HEaaN, he is actively working on homomorphic encryptions and their applications including machine learning, homomorphic control systems, and DNA computation on encrypted data. He is particularly known for his work on an efficient algorithm on strong DH problem. He received the best paper award in Asiacrypt 2008 for improving Pollard rho algorithm, and the best paper award in Eurocrypt 2015 for attacking Multilinear Maps. He was also selected as Scientist of the month by Korean government in 2018 and won the POSCO TJ Park Prize in 2019.
