His main research interests include scientific research and teaching. In 2003, he participated in the completion of the project "Parametric Computer Theory and Application" and won the first prize of National Natural Science nominated by the Ministry of Education (ranked fifth). In 2005, the "Virtual Experiment Platform Based on Component Services" won the second prize of Hunan Science and Technology Progress Award (ranked third), and the completed scientific research project 2005. 1-2007. 12 was sponsored by the National Natural Science Foundation of China: "Research on the Theory, Method and Key Technologies of Anonymous Communication", which studied the key technologies of anonymous communication, including the measurement of anonymous performance. A group anonymity mechanism in distributed and centralized environment is proposed, and the relationship among anonymity, management overhead and group members is analyzed theoretically. Aiming at the completely distributed keyless environment, an anonymous communication mechanism without public key encryption is proposed by combining random network coding with anonymous road construction mechanism. At the same time, the privacy of the source node of the sensor network is studied, and the source protection strategy of the wireless sensor network based on angle information is proposed, which greatly improves the security time of the source node.

Research on short-distance priority packet rerouting method in anonymous communication,No. 10, 2009. Journal of Software, in 2004, 15 (4) and 56 1-570 undertook scientific research projects funded by the National Natural Science Foundation: "Research on the Security and Reliability of Wireless Networks Based on Network Coding", aiming at studying the application of network coding in wireless network optimization. Specific optimization objectives include the efficiency, reliability and security of wireless transmission. On this basis, a network coding scheme suitable for wireless network environment is proposed, which can achieve multiple optimization goals, and the related research results are compared with wireless networks.
