The Design And Implementation Of SSO Interface In E-government

At present, the business system in the government departments has been separated into fragmented operational systems, and lacks mutual share of information resources and operational synergies. They result in the so-called "islands of information". In addition, there are secure borders existed in which causes users to need to enter a user name and correspording password while accessing different applications and this makes users inconvenient and also brings security issues. Therefore, the integration of government information resources, information share and the establishment of inter-business coordination, will play important roles in eliminating "information islands", realizing "that logged more roaming", strengthening exchanges with the people, reflecting personalized services, and promoting a service-oriented government, it is particularly important to the building.In this paper, the study is based on a project in Hubei Province chief portal foundation. According to the actuality of Hubei e-government and the "integration of legacy systems, integrated follow-up application" principle, the solution of the chiefportal considering of the core functional module------Single Sign-on in chief portal,SSO model based on the broker is proposed after comparing the current several SSO models, which is combind with the overall system design idea and the current department. By analyzing its mechanism principle, SSO design in the overall system is given and the detailed design process is shown in this paper. For confirming the safety in single sign-on 3DES key information the Application Layer in issused to encrypt and decrypt. Considering of the application integeration problem in the Hubei Provincial Chief portal, the application system integration specification is designed in detail. Finally, the SSO in Hubei Province Chief portal is implemented, and its running and effects show the effectiveness and feasibility of this method.In this paper, the main work lies in the establishment of SSO based on the broker model. In practical application, to realize their functional integrated business applications and integrated systems through redirection and data encryption technology, the realization of e-Government will play an important guiding role and value in the sharing information, promoting the business coordination of departments, realizing the further decision support systems and the vertical business channel among departments.
