A Design on Single Sign-on System of Enterprise Information Portal based on Security Domain

Enterprise information portal integrates all applications of enterprise based on the distributed architecture of Web services to provide a unified entrance of accessing all kinds of data,applications and services to users.The first problem of enterprise information portal is single sign-on system.This paper introduces a design scheme on single sign-on system of enterprise information portal.Then the paper dynamically divides the security domains based on the different coupling degrees of the Web service applications,and utilizes the authentication mechanisms of delivering tokens between Web applications and encrypting the shared Cookies for cross-site access and cross-domain access respectively,which both alleviates the complexity of the authentication process for cross-domain access and guarantees the security of the system.
