The Application Of Security Middleware In The Local Area Network

With the development and popularization of network technology, the society of human has entered the information age, cross-regional and cross-sectoral information exchange through the network, and automated processing of information integration have become urgent needs of people and even various business units. However, in the development of the network technology, the security vulnerabilities of Internet posed a serious security threat to the network security, some illegal users on the network using these security vulnerabilities eavesdropping, forgery, tampering and do other illegal operations on data that transmitted over the Internet, which seriously hampered the security of information transmitted on the network, the problem of network security has become major problems of the development of information technology in today's society. At the same time, taking into account the wide range of network security products and the update speed, from the perspective of product development, how to avoid duplication of product development process and shorten the product development cycle, thus saving the cost of product development have become the focus of developers. From the perspective of customers, the integration and simplicity of security products has taken more and more attention of the users of the product. Therefore, how to solve these problems and develop new applications are very real and difficult problems. The proposed middleware, not only solved these problems, but also has been widely used.Middleware is a technique developed in recent years, which provides users with information security services, and is widely used in e-commerce and other areas. This technology combined the information security technology and middleware technology, and took object-oriented and component technology, analyzed the service request of public safety in application system, and separated the software from the entire system, which provided a service interface for the application system. Security middleware technology has solved the issues of high costs, poor interoperability and usability of software in current field of information security.Based on middleware technology and combined with the current status of security middleware technology, this paper established a simple security middleware model in the local area network by using Java network communication technology and some basic principles of PKI technology. The main research work is as follows:(1) Analyzed four basic functions, including encryption and decryption, authentication, digital signatures and integrity in Security Middleware Model, and established a simple security middleware model in the local area network.(2) Presented the overall design of the system and the chart of system function structures.(3) Designed the system in detail from three aspects of the graphical interface, network capabilities and security features, and gave specific implementation.The system established in this paper reflected the basic functions of security middleware, and could process the communication information between server and client, which enables the security of communications to be strengthened. Testing experimental results show that the system established in this paper basically reached the intended target.
