Identity Management System Based On The Cas Petrochemical Hospital Design

As a third party petro service provider, the petrochemical school provides crude oil inspection and assessment service to various refinery enterprises. With the help of informationalised system, the school enhances the staffs efficiency exponentially. As these informationalised systems are on the rise, the staff are facing with two major difficulties, one is the issue of chaotic management of application system accounts, the other is the issue of typing usernames & passwords repeatedly while logging on to the application system. How to manage the application system effectively and how to reduce staffs login times, are the two difficult issues the petrochemical school must solve. Through a CAS hased ID management system, the school solves the current issues encountered, and also realises the purpose that staff can log in to multi application systems by typing usernames and passwords only once everyday through single sing-on.First, by way of analyzing service demands of the school, deployed environment of the application system is introduced, the coefficient of difficulty of the current integration of application systems and drawbacks existed in the management process, are analyzed, also the necessity of setting up the petrochemical school ID management systems is demonstrated. Based on these, the core functions of the ID management systems are discussed, the main process of operations of the ID authorization is analyzed, and systematic demands of the CAS authentication technology based ID management system are made clear. Then, the overall framework of the ID management system is analyzed, core sub-systems like ID authorization and authentication are designed in details, of which it's mainly argued that how the CAS authentication technology realizes single sing-on of the multi application systems of the petrochemical school, and how the ID authorization and authentication are integrated together closely to realize the integration of enterprise application system and its users. Finally, the system security and framework's extensibility are analyzed.
