轻量级门户单点登录服务机制

信息门户的建设过程中需要容易实施且灵活高效的整合模式.为克服传统单点登录机制无法满足在动态松耦合环境下实现快速整合的缺陷,结合面向服务架构思想,提出一种轻量级门户单点登录服务机制(LSSO-Service,Lightweight Single Sign-on Service),可为门户整合提供结构简单、完善通用、松散耦合、快速机动的单点登录服务.LSSO-Service基于高于对象层的分布式服务集成模式进行功能划分,可实现采用不同技术的应用系统在门户中的快速动态整合.阐述了LSSO-Service的设计思想和工作原理,并通过在国内某大型水利信息门户中的应用实践,说明该研究结果对于门户建设具有较高的理论意义和参考价值.

Lightweight single sign-on service mechanism for portal

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.
