Research And Application On Single Sign-On In Electronic Government

The application of Single Sign-On technology in the electronic government are studied in this dissertation. The thesis consists of six chapters. The main contents are as follows:Firstly, the concept and research status of Single Sign-On are expounded.Secondly, the basic meaning of information security in the electronic Government (E-Gov) is summarized. it analyzes in detail the secure capability, secure technology risk and secure technology of the E-Gov information, mainly the efficiency, security, integrality, differentiate and checkup of E-Gov information security. Also, it analyzes the five aspects of physics security risk, link security risk, network security risk, system security risk, application in the technology security risk, and present relevant technology on how to avoid these security risk.Thirdly, several regular Single Sign-On model are analyzed, their theories and architecture are expounded. Then it compares and analyzes them about their implement, management, security and usage.Fourthly, a new type of Single Sign-On is proposed. Its architecture is analyzed, and their theories of every model are mainly expounded.Fifthly, analyze the Single Sign-On model design and implement at SharePoint Portal Server2003, including simple introduction of SharePoint Portal Server2003, it's architecture theory, configuration procedure and Web Part's programming implement at login interface, how to use and protect users'information through configuration and interface programing among SharePoint Portal Server2003 SSO, applications and SQL SERVER2000.Sixthly, Analyze the design and implement based on SSL SSO, including the design of SSL SSO architecture, and based on authentication of X.509, the design of LDAP directory server, the design of SSL communication protocol, the design of certificate authentication. Finally realize Single Sign-On based on SSL.A set of Single Sign-On model is set up comparative completely.
