Abstract�� An integration framework with easy and efficient implementation is necessary in construction process of information portal. To overcome the limitation that traditional single sign-on mechanisms can-t achieve fast integration in dynamic and loose coupling environment, a novel lightweight single sign-on service mechanism for portal (LSSO-service) was proposed based on service oriented architecture. LSSO-service-s business logic functions were divided according to a distribute integration framework with services higher than object layer. By this means, the simple, adaptive, loose-coupled and flexible single sign-on service could work well, and those application systems based on different techniques might be quickly integrated into portal with a unique entry. The design idea and functional principle of LSSO-service were both presented. To validate the high significance and feasibility of the proposed approach, an integrated prototype was carried out.
