Information dissemination often takes theform of XML documents that are made available at Web servers, or that are actively broadcasted byWeb servers to interested clients. These documents often contain information at different degrees ofsensitivity, therefore a strong XML security platform and mechanism is needed. In this paper wedeveloped CIT/XML security platform and take a close look to syntax and processing of CIT/digitalsignature model, CIT/encryption model, CIT/smart card crypto and SPKI interface security models.Security services such as authentication, integrity and confidentiality to XML documents and non-XMLdocuments, which exchanged among various servers, are provided.展开更多

With the development of economic and cultural globalization, the demand for English has gradually increased. Traditional college English teaching cannot meet real requirement, so college English teaching reform is imperative. With the development of online platform, the Internet has brought a great impetus to the curriculum reform. The author thinks that ＂MOOC＂ and College English Teaching Reform have a good point of combining, but there is still a problem remaining to be solved： How to make good use of＂MOOC＂ for College English Teaching Reform service has a lot study space in the future.展开更多

To solve these problems, the proposed design of a unified management platform for a variety of heterogeneous network security equipment. A brief introduction for the main functions of the platform.The article proposed a traffic handling mechanisms of heterogeneous security devices, allowing the platform to support heterogeneous security devices.展开更多

Cyworld was one of the most successful SNSs in the world, but its international expansion efforts failed. Facebook＇s open technology has had considerable influence on various sectors of the economy and society and allowed it to become a dominant SNS at the global level, whereas Cyworld has remained a local SNS. Facebook＇s open platform and application programming interface （API） pose a serious challenge to Cyworld＇s walled-garden approach. Cyworld is based on strong ties fostering close relationships, whereas Facebook expands social networks through its open and weak ties and has more network power than Cyworld. Therefore, openness is the main reason behind the rise of Facebook and the fall of Cyworld.展开更多

It also presents the train control and monitoring system （TCMS） software development platform, the TCMS testing and verification bench, the EMU driving simulation platform, and the EMU remote data transmittal and maintenance platform. All these platforms and benches combined together make up the EMU life cycle cost （LCC） system. Each platform facilitates EMU LCC management and is an important part of the system.展开更多

This article introduces the present situation of network information security, discusses the connotation of network information security, and analyzes the main threat to the security of the network information. And we separately detailed description of the data monitoring platform architecture from the data layer, network layer and presentation layer three levels, focuses on the functional structure of intelligent database platform, and puts forward to measures that ensure the safety of the platform and the internal data security. Through the design of the platform to improve the information security system has certain significance.展开更多
