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.

Trusted computing is a hot topic of information security technology research nowadays. It was developed based on computing and Information Systems. At the same time, business processes for e-commerce and Web service applications, suppliers and customers define a binding agreement or contract between the two parties, specifying quality of service (QoS) items such as products or services to be delivered, deadlines, quality of products, and cost of services. The management of QoS metrics directly impacts the success of organizations participating in e-commerce. In this paper, we discuss the present situation about QoS in the environment of trusted computing. It describes the factors related to each attribute, as well as possible tradeoffs and existing efforts to achieve that quality. The paper also discusses key issues in services level agreements that are used to contract the level of services quality between service providers and users.

Mobile e-commerce systems are the big trend of international economy and social development now days, and also the key process of industry upgrade, industrialization and modernization in our country. Mobile e-commerce systems are considered as the backbone of the manufacturing industry in China, Vulnerabilities in web applications continue to be the most frequently discovered security problem. This article illustrates a trusted operating systems how to provide a flexible solution to the problem of application for e-commerce. With the help of Chinese Wall, web services are becoming popular in Web applications. In the end, we present strategies for e-commerce application: trusted e-commerce module.

The ordinary cloud system is confronted with various threats in trust and security perspective, which have influenced the extensive use of cloud system. Aiming at the defects in the trusted secure design of the ordinary cloud system frame, a trusted secure cloud system has been designed.

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.

Based on the TNC architecture, using a trusted network of repair techniques in the trusted network access scenario does not meet the requirements of integrity verification solution for end users. Put forward a credible fix the overall network design, reliable model restoration and repair services, network workflow. The system is in need of restoration to provide safe and reliable repair end-user data transmission, providing a humane, reasonable repair services to ensure the credibility of fixed network and the isolation effect of the terminal to be repaired and strengthened the security of fixed server. Realized the classification of various types of repair resources management, restoration of resources in ensuring the transfer of fast, reliable, based on the performance with a certain extension.

The existence of trusted subjects is a major complication in implementing multilevel secure (MLS) systems. In MLS, trusted subjects are granted with privileges to perform operations possibly violating mandatory access control policies. It is difficult to prevent them from data leakage with out too strict confinement. This paper reconsiders the privilege from the view of sensitive data and presents a dynamic trusted domain (DTD) mechanism for trusted subjects. In DTD, a domain is associated with a special label structure (LabelVector) distinguishing security policies and builds an isolated environment based on virtualization for a certain trusted subject. The channel for the trusted subject to communicate with outsider is controlled by a trusted request decision maker (TRDM). Only the request satisfies the rules on domain label and security levels can be passed through.
