The Single Sign On And Unified Authentication System Of Tianjin Airport Information Platform

The Single Sign On and Unified Authentication System is for system integration requirement of Kong Gang government, via going through the core business need for building Kong Gang information platform, using the current popular open source SSO solutions, which is cover the whole life of Unified Authentication System from architecture design to implement. This integrated system is aim to create a unified working platform, which will combine with all kinds of business sub system and facilitate different data source of information, to let off the system stress and solve information isolation problem. On the other hand, this system will make information query and application access be simple and convenient by offering a uniform approach for user access, which integrate information and application to initially construct a basic service layer. There are two mainly points of the implementation of this system. Firstly, varies of business application and services can be integrated by offering a uniform approach for user sign on and authentication. Secondly, a further integration to provide a unified authentication, resource sharing and other services in the future.To meet the requirement for extend for future, The Single Sign On and Unified Authentication System adopts currently popular multitier layer architecture,within J2EE standard. and has formulated the as perfect as possible interface specification and the development standard, which can be used for load balance and servers cluster.At the same time, with the help from currently popular SSO open source production (the CAS from Yale), and light direction access protocol, the system simply the implementation of single sign on and user authentication functionality. This article described a system, which is seeking for a low expense, high efficient way to provide ideas for current domestic smart city construction and promote the development of the industry in this field.This Article describes the background of system development, and current situation of domestic and foreign companies in unified authentication solution. By investigating and consolidating information in wide way. The article clarify requirement from two sides, the function and non-function section, and clear the main points to solve for future construction. In the phase of system design, the description involve core technology used, design thought, perspective in deployment,functionality and some detail model, especially in terms of the authentication process and direction service layer. Finally, it analysis some core issues in implementation of system.In summary, we design and implement the ingle Sign On and Unified Authentication System based on the analysis of business requirement.
