The Framework and Implement of Trusted Network Connection Based on Separation of Controlling Flow and Data Flow

The paper proposes a trusted network connection frame based on the separation of controlling flow and data flow, giving priority to maintaining data stream transmission. This is done through controlling the flow of communication on both sides of the identity authentication and trusted state assessment, and updating the access control policies of both sides, so as to maintain data stream transmission control. On the one hand, it can guarantee the real-time transmission of business data and on the other hand it can improve the efficiency of communication participants’ trusted state assessment, which is suitable for the intensive real-time requirements of industrial and business data.
