Security Scheme Design And Realization Of City Electronic Service Under The Public Customer End Enviorment

Along with the development of technology of Internet, the human society marches toward one brand-new information age. In the course of constant promotion of the social informationization, people are enjoying the facility that the electronic informationization bring. The change quickening people of the information technology enjoy the convenient speed at the same time. As the subject participant of all kinds of social activities and beneficiary finally -The citizen, often receive the restrictions of objective affairs, such as culture background, economic condition, technological bottleneck,etc., Unable to fully enjoys information service through the suitable channel. Public customer ends break that kind of restrictions and make the information service available anytime and anywhere.That a citizen who uses the power terminal station in the public place that city electronic service serve can enjoy various kinds of services that can't obtain in home, such as the social security card information service, the public transport card inquiry and public information inquiry. The essence served in electronization is to provide citizens convenient service by integrating services on the public customer ends.Compared with home PC, public customer ends are totally in the open environment, The open one faces the masses of citizens, offers various kinds of services open, and the serving is in one open Internet environment too. The server of electronic service system which integrates the services is open to service providers. So what this paper is discussed is the security issue in the process of services integration under the environment of such a open public customer ends, open Internet, and the open Front End Server. For being convenient for people, services providing should base on the foundation of security. On the premise of ensuring citizen's interests, it is really convenient for people to serve and offer.Firstly, this paper introduces the background, features, structure and running principle of city electronic service under public customer ends environment in detail. Through analyzing the security requirements of public customer ends, Front End Server and electronic services in the view of physical security, running security and information security, this paper sets forth the complete security scheme.This paper brings forth tertiary key system structure and build system own PK.I (Public Key Infrastructure) .It also proposes SSL transmit scheme safely by the Sockets of foundation. The proposal of system security scheme solves data safe transmission problem in the form of XML among the distributed environment The system adopts UML target's modeling language and carries on modeling, utilizes J2EE technology to structure frames systematically. This paper reviewed and summarized the subject at last, and looked into the distance of the development in the future of the subject.The research topic of this paper offers a very good security reference model for the application of distributed system under the public customer ends. The component of security module in the system can be used in the other security system, so it has equal practical value for other application system.
