Research on Power Terminal Access Control Technology Supporting Internet Interactive Service in Smart Grid.

With the continuous development of smart grid interactive business applications, the existing terminal access mechanism is difficult to ensure that all types of power terminals access to power information network security. Based on the idea of trusted computing and trusted network connection, this paper proposes a power terminal security access architecture for power interactive business from terminal security access and access control, terminal encryption and content filtering, and establishes architecture of supporting for interaction business from Internet and terminal security access, enhances the external network interactive services and terminal access authentication and access control capabilities in order to improve the security of terminal access to protect the strength of the Internet to ensure interactive services and terminal access to the trustworthy.
