However, when the authentication server is down or unavailable, users cannot access these Web services, regardless of whether they are operating normally. Therefore, it is important to enable continuous use alongside SSO. In this paper, we present an identity continuance method for SSO. First, we explain four such continuance methods and identify their limitations and problems. Second, we propose a new solution based on an identifier migration approach that meets the requirement for identity continuance. Finally, we discuss these methods from the viewpoint of continuity, security, efficiency, and feasibility.展开更多

The appli-cation and technology architectures of the collaborative platform are elaborated in this paper,and the major key technologies on the platform are also expounded, which includes realization of many governments ap-plications’ scale integration and collaborative application, business model driven software development plat-form based on SOA, SSO, tans-departmental and cross-level multi-engine clustering protocol. Based on the "clustering application"design, to maximize the utilization of hardware, software resources and administra-tive resources of the provincial government collaborative platform, rural districts and counties can build their own platforms based on the provincial platform. The platform having been running for over 2 years shows that planning of urban and rural e-governments’ construction and maintenance is achieved, thus reducing costs greatly and improving governments’ functions.展开更多
