Design And Implement Of Unified Identity Authentication System E Base On Service Orient Architecture

With the development of the network and information technology, Enterprise's informatization degree increased very fast. In the course of informatization, there emerges more and more application system, and improve the management and operating efficiency. But it increases the network resource, and makes it difficult to maintain the net order. It leads to all kinds of insecurity, and distributing system management lack of security policy and irregularity security strength.Existing unified authentication that system utilizes directory service partly solves the problem of unified authentication. However, for its C/s mode based, the system is insufficiently in using and integrating. With emerge of Service Orient Architecture (SOA); it can lead to easy maintenance and development. It also can make business and IT more integrate with each other.On the basis of the development of single sign on, the paper proposes a unify identity authentication system based on Serviced oriented architecture. This system can access all network resources on commission. Users are required to input their usernames and passwords once. As a valid user, he can access any application that uses the single sign on with the same user name and password. This system improves the efficiency of users and administrators, reduces expenses of the network operations, and makes the whole system more secure and convenient.Once the user gets the authentication token, he can access the web application using the system. So it is undeniable that the security of the token, the trust of the application and the authentication server has become the subject matter influencing the system to implement. There are many secure problems of network, such as the man in the middle attack, reply attack.We use web service as its developing foundation between components. This system uses XML, SOAP technology and implements identity authentication function using tickets transmitting. In additional, the system can be integrated easily. With the unify identity authentication system being gradual and perfect, it will play an important roe among the information security system of network, and network management will be simpler and effective.
