Research Of Secure Transmission Model Of Sensitive Information In The Open Network

With the rapid development of E-government, E-commerce and E-payment,original sensitive information system, fully using the means such as physical isolation,can no longer fulfill the need of application requirements today, and are inevitablytransmitted through network. So research of transmission of sensitive information inopen network has potential application and theoretical significance. This paper focuseson research how to build a secure transmission model of sensitive information in opennetwork. Details are as follows:First of all, we researched and analyzed the status of domestic and foreigninformation security system.Secondly, we defined and characterized the features of open network. We alsoresearch the security characteristics of Internet, mobile networks and wireless networks,and summarized the vulnerabilities and security threats that an open network has to facewith. Then, we classified the security requirements information of end to endtransmission in the open network.Thirdly, we proposed a security model of sensitive information transmission in theopen network based of the security requirements, detailed designed each module in themodel, and proved the feasibility and security of model.Lastly, we put forward two typical application programs based on the securitymodel, which are sensitive network to sensitive network, and the terminal to sensitivenetwork. From end to the sensitive network, this program covers the whole design.
