The Design And Implementation Of The Qinhuangdao's Education Unified Authentication System

In the era of education informatization 2.0,the experience of the construction of the 1.0 era was summarized,and the development goal of the "Internet + Education" platform was put forward,which pointed out the direction for the application of educational information application.The biggest feature of the "Internet + Education" platform is to integrate various types of application systems at all levels,and gradually realize interoperability,convergence and opening between systems.The Qinhuangdao Education Unified Identity System,which is discussed in this paper,serves as a supporting platform for the service information application of the city.It can solve the problem of unified authentication between different systems and the sharing of information resources between systems.The unified authentication system can also access to the social open account authentication system,such as: QQ,WeChat.Qinhuangdao City Education Unified Identity Certification System not only serves as a support system,but also serves as a standard to all counties and schools,and plays a leading role in the construction of information technology at all levels.This thesis mainly introduces the process of designing and implementing the Qinhuangdao Education Unified Identity System based on the popular open source software Yale CAS.Firstly,the two key technologies involved in the system(Web Services technology and single sign-on technology)are analyzed,two different mainstream technologies of Web Services are compared,the theory and popular technology of single sign-on are introduced.Secondly,the requirements of the system are analyzed in detail from the function and non-functional requirements.the function requirements include unified identity,unified authentication,basic data management,data sharing interface,the safety,technical standard and performance requirement are introduced in the non-functional requirements.Thirdly,on the basis of demand and popular technology,the overall design and detailed design of the system were carried out,and the functional modules process and technical specifications of Qinhuangdao Education Unified Identity Certification System were determined,the system is implemented by the improvement and extending of Yale CAS.Finally,based on the preliminary work,the implementation of the system was briefly described,mainly introducing some implementation path of the key modules,and describes the operation and optimization of the system.
