Research Areas

In the early days, he was engaged in the research of quantum affine algebra and representation theory, while his current research direction is post-quantum cryptography. Moreover, he has served as the co-chairman of the International Conference on Post-Quantum Cryptography for three times and is one of the prominent scholars of multivariate cryptography in the world.
