For reasons beyond our control this event has been cancelled.

In this talk, we will present some resent results on Ring Learning with Errors (RLWE)-based key exchanges. We will first present the new passed-based RLWE-based authenticated key exchange. Then we will present a new authentication scheme, where a prover tries to proves that he or she knows a secret solution to the RLWE problem without revealing any information on the solution. For an interactive scheme, we can prove the zero-knowledge property. We will also present a non-interactive scheme, and show how it can be used to build RLWE based key exchanges, where key reuse is also secure.

Jintai Ding is a professor at the Department of Mathematical Sciences of the University of Cincinnati. He received his B.A. from Xian Jiaotong University, an M.A. from the University of Science and Technology of China and a Ph.D in mathematics from Yale in 1995. He was a lecturer at the Research Institute for Mathematical Sciences of Kyoto University from 1995 to 1998. He has been a faculty member at the University of Cincinnati since 1998. For 2006-2007, he was a visiting professor and Alexander Von Humboldt Fellow at Technical University of Darmstadt. He received the Zhong Jia Qing Prize from by the Chinese Mathematical Society in 1990.

His main research interests are in cryptography, computational algebra and information security. He was a co-chair of the second international workshop on post-quantum cryptography. He and his colleagues developed the Rainbow signature scheme, the GUI HFEV- signature, the Simple Matrix encryption scheme and the LWE-based post-quantum key exchange scheme.
