讲座时间 2017-06-14 15:00:00
讲座地点 北校区新科技楼 1012会议室
讲座人 Prof. Chaoping Xing
讲座人介绍 Chaoping Xing is currently a professor and deputy head at School of Physical & Mathematical Sciences, Nanyang Technological University. In the May 1990, he got his Ph.D degree in Mathematics from University of Science and Technology of China, Hefei, China. In the Dec. 1987,  he got his Master degree from Xidian University, Xi’an China. In 2013, he earned the Kloosterman Visiting Chair Professor at Leiden University, The Netherlands. In 2003, he earned the National Science Award (team), Singapore. He was supported by the Hundred Talent Program, China in 2001, and the Alexander von Humboldt Fellow, Germany in 1993.   Currently, his research interests focus on coding theory, cryptography, number theory, algebraic geometry, quasi-Monte Carlo methods. He is the editors of IEEE Trans. on Information Theory, Finite Fields and Their Applications, International Journal of Computer Mathematics, Science China Mathematics, Journal of Systems Science and Complexity. He has published lots of papers and was cited 2800+ times. In the recent five years, he had 17 IEEE-IT journal papers, besides, his research results were published in the top-tier conferences of computer sciences, such as STOC, CRYPTO,  SODA.

讲座内容 In 1994, Shor showed that both integer factorization and discrete logarithm problems are in fact easy to solve on a quantum computer, based crucially on the laws of quantum physics. As a consequence, almost all currently deployed public-key cryptosystems will become completely insecure if quantum computers become a practical reality.  Post-quantum cryptography refers to conventional cryptosystems that are secure against both quantum and classic attacks, and can interoperate with existing communication protocols and networks. It seems unavoidable that sooner or later the modern public key cryptography infrastructure will need to move to the post-quantum one, to ensure a smooth and secure transition from the currently used public-key cryptography to its postquantum counterparts. In this talk, I will briefly survey this topic.
