Study On Secure Transmission For Network Connection Control Systems

Along with the rapid development of network technology and information sharing needs,Network connection control system has become a important solution and tool for multiple networks or multi application information transmission security.The network connection control system consist of secure authentication and access,secure transmission,secure control,secure management and other key technology.This thesis focuses on security authentication and secure transmission technology,the main work as follows:(1)With the background of application information between network transmission security,after analyzing the security technology such as secure transmission,designed a secure transmission frame,then described and analyzed the components and how it works.(2)After the frame proposed,put forward a set of secure protocol which was based on safety label,and described the details on safety authentication and safety transmission,then analyzed the security and reliability of the frame,made a deep research on the frame's access authentication problems to the avoid existing key management problems,and proposed the corresponding solutions,which also solved the optimization problem of the transmission efficiency.(3)Designed the secure transmission system model,and experiment verified the secure protocol,secure authentication,key management technology.The proposed frame is actual valuable in engineering practice.Thesis has good engineering practice value on internet security control system model research and system design and implementation.
