Trusted Network is a new research direction of the Internet. On the basis of trusted LAN, this study puts forward a trusted label of the trusted terminal, which can solve the DDOS attack efficiently and control the abnormal flow easily in the trusted LAN. In addition, it proposes the label’s verification technology, so as to ensure the execution efficiency of some real-time business in the gateway. Above all, the trusted label and the verification technology make the LAN more controllable and safer.

In this paper, the application of Trusted Computing Platform is discussed. It is pointed out that the purpose of network management information system by trusted Computing platform is to set up a trusted network system. Based on the analysis of the environment of the trusted network information management system, we employ a trusted computing model in the information system of graduate student at our university. The implementation of network trusted management information system indicates that this method will improve the security of information system.

This paper discusses the trusted computing model which is based on existing computer network. The present trusted computing platform has to make big changes on personal pc hardware system in order to realize the trusted computing platform module on pc mainboard or hardware. To solve this, here presents a layered trusted computing platform module, which replaces the original trusted computing platform module with implemented modules on server. The prototype model ensures the trust measurement being implemented on any logical layers of the trusted platform with making a complete trust chain from the beginning of the boot stage of the client operating system. By creating a trusted computer platform with all the computers in the system, real trustworthiness in the entire local area network can be realized.
