Jooyoung Lee

Jooyoung Lee is an Associate Professor in the School of Computing and the Graduate School of Information Security at the Korea Advanced Institute of Science and Technology (KAIST). His research covers provable security in symmetric cryptography, symmetric ciphers for advanced cryptographic protocols, and post-quantum cryptography based on symmetric primitives. KAIST’s profile lists his major achievements as the post-quantum signature scheme AIMer, a framework combining CKKS homomorphic encryption with a symmetric cipher, and a permutation-based deterministic random bit generator (DRBG) with stronger security and efficiency.[S01][S02]
