Research Of Security Middleware For Internet Securities Transaction System

Recent years, the middleware technology has been developed rapidly. More and more middleware has been applied in practice. Its research is of great practical significance.At present, the main study of middleware technology is the study in network technology which mainly focused on the integration and sharing of network resource and unified management; the mobile middleware research oriented to mobile computing environment; the service-oriented qualitative research namely study of the high availability, high security, fault-tolerance and so on.This article studies the security of middleware on the basis of the related research to design the high-security specific middleware in the area of securities industry and to build the security access of network securities trading system.the main contribution of this research is to study the safety of the securities trading system mainly including the security of system operating environment,client identity authentication and access control, the transmission security of transation data,clients' security, exception handling and recovery, and the security of clients' securities funds information.then, the corresponding solution has been put forword.These studies revealed the key and difficult points of the Securities and Exchange system security which based on the previous studies and the improvements and exploration has been made.Through creative integration of securities trading security services and middleware technology,the Securities and Exchange dedicated middleware that has strong design scalability and the higher security has been designed to realize reliable UPD and load balancing,high-reliability access layer.Firstly, this article describes the commonly used middleware which plays great significance for the development of middleware described in this article.Secondly, the security requirements of securities trading system have been analyzed and the security flaws of Internet securities trading system has been pointed out. In response to these security issues, the security access layer of the network trading system has been introduced that is the framework of the financial middleware. It will provide a variety of security measures and enhance the security of the system through security access layer. Thirdly, this article studies the sub-module of the security access layer including a unified user authentication module and a digital certificate module. The security mechanism, token design and main encryption algorithms of the subsystem are researched. It realizes the security controls of access layer through the combination of digital certificates and improves encryption algorithms.Finally, it builds the securities trading system based on the financial fundamental middleware and carries out the test to verify the overall stability of the system.
