针对目前数字化校园建设中各种跨业务范畴应用系统各自独立运行、独立认证的问题,本文分析研究单点登录认证框架在校园共享系统开发中的可行性与实现流程。使用集成SSO机制的J2EE开发框架整合改造已运行使用的各业务系统,与新开发的Web应用系统耦合,实现链接。实现安全有效的用户管理和不同域上应用系统的统一认证。     

一种综合认证策略在企业信息资源单点登录技术中的应用

本文提出了一种综合的身份认证策略在单点登录技术中的应用。该策略采用双向认证,保证用户和认证服务器的合法身份。使用用户身份级别授权机制,很好地保护了受访资源。采用SSO代理,降低单点登录系统和Web应用的耦合。使用该策略,客户可以安全有效地实现＂一次登录,自由切换＂的目的。文中给出了方案的总体思路,详细地描绘了登录流程,并分析了其安全性。     

基于SSO技术的信息门户网站构建

首先对企业信息门户、统一身份认证、单点登录等相关技术做了介绍,然后对现有SSO解决方案进行了阐述。最后,设计了一个SSO模型,并结合国家科技支撑计划项目的需求,开发了一个现代人口与生殖健康公共服务信息门户系统。     

数字化校园环境中统一身份认证系统模型研究

数字化校园建设是推动高校信息化建设的重要系统工程。高校中存在多个Web应用系统,访问多个应用系统需要单独登录,难以实现单点登录。提出了一种完整统一、高效稳定、安全可靠的统一身份认证系统模型,该系统能实现身份数据的统一存储、统一管理,实现全校各类应用的单点登录,以及各类访问与操作安全审计,同时还可提供便利工具进行系统维护及管理。     

一种基于单点登录的开源课程群系统

为高效地管理和应用高校的网络课程,满足课程教学过程中不同类型用户的实际需求,本文提出了一种基于单点登录的课程群系统,采用用户信息统一管理、分布式子课程群服务的应用模式,并以单点登录认证机制实现系统整合。系统以开放源代码模块进行构建,以耶鲁大学开发的CAS结合OpenLDAP实现统一认证,以Moodle教学平台提供具体的课程服务,实践表明它是一种可靠、高伸缩性的开放课程群系统。     

一种基于单点登录的实验室统一身份认证方案

该文在对目前主要单点登录实现方法进行比较分析的基础上,针对高校实验室应用和管理要求,结合本单位应用实际,提出了一种基于单点登录的实验室统一身份认证方案。重点介绍了基于LDAP的统一身份认证方式以及基于CAS的单点登录系统的设计方案,分析了具体的实现细节,并对相应的部署方法和关键技术进行了重点说明。     

校园信息门户统一身份认证系统的设计

基于单点登录技术,构建一个统一身份认证服务平台,有效地整合校园网络中所有的应用系统和资源,提供统一入口,用户只进行一次登录,就可以实现应用漫游,访问所有被授权的应用系统,对统一身份认证系统整体设计思想、结构框架、关键技术的实现进行论述。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

The Reader Response Approach to Teaching of English Literature

During interview with English majors, it was found that a majority of students expressed disappointment with their experience of English literature classes. Students' dislike of learning English literature appears to be the major problem of teaching English literature in China. Reader response approach is a good way to solve this problem. In this paper, I explain the rationale behind the reader response approach, such as its origin, definition, features, assumptions, and strategies. Then I illustrate how reader response approach works as a teaching strategy by presenting several teaching models. At last I evaluate its usefuiness for teachers and present the advantages of reader response approach in Chinese context.
