Jintai Ding is one of the designers of the quantum resistant key establishment standard by the US National Institute of Standards and Technology (NIST), ML-KEM (FIPS 203), formerly Kyber. He is the inventor and patent owner of the first quantum key exchange which was one of the two patents licensed to NIST for ML-KEM. He is Dean of the School of Mathematics and Physics at Xi’an Jiaotong Liverpool University and a Charles Phelps Taft Distinguished Professor Emeritus at the University of Cincinnati. He and his colleagues developed Rainbow signature, a third round candidate and finalist in the NIST post-quantum standardization process. He and his colleagues completely broke a NIST second round post-quantum signature candidate LUOV and a third round candidate GeMSS (HFEv-), for which they won the best paper honorable mention award for Crypto 2021. In March 2025, his group broke the world record by solving the Darmstadt lattice SVP 200 challenge and again the SVP 210 in February 2026.
