Research on Security Access and Authentication Technology of Power Terminal Based on TNC

Abstract

Along with the construction of the strong smart grid, many intelligent terminal equipments and wireless communication devices are widely applied to the smart grid, bringing convenience to the construction of the smart grid business systems as well as some serious security issues of confidentiality. The data transmitted through the wireless channel by various types of wireless power terminals in the wireless network communication is vulnerable to eavesdropping and other attacks. In this paper, we proposed an security access architecture and authentication protocol of power terminal based on the theory of the trusted network connection (TNC) and gave the specific authentication protocol process based on the practical application in the smart grid environment. Eventually, we confirmed that the design of the scheme can ensure the integrity and security of the terminal itself according to the safety analysis, so as to build the trusted computing environment of electric power communication network system, ensuring the safety of the whole smart grid application environment.
