I am an associate professor in the School of Cryptology, University of Chinese Academy of Sciences (UCAS). Please visit my UCAS website for more information.

I received Bachelor’s degree from the University of Science and Technology of China (USTC) and received Ph.D. from the University of Chinese Academy of Sciences (UCAS).

My research interests lie in the general area of cryptography and security, particularly in applied cryptography, cryptographic engineering, cryptographic testing and evaluation, as well as high-performance cryptographic computing. My publications include CCS, HPCA, CHES, ACSAC, ESORICS, IPDPS, ICPP, TIFS, TC, TPDS, etc.

My job focuses on applying cryptography in reality. Parts of my achievements include:

• High-performance cryptographic servers (20Mops+ of digital signature and FIPS 140 certified).
• Secure and fast software cryptographic implementations (numerous publications and implementations).
• Cryptography evaluation methods (2 fundamental standards, i.e., GB/T 37092 and GB/T 39786).
