Application And Design Of SSO In Digital Campus Systems Based On CAS Protocol

With the continuous development of information construction, more and moreapplications in the digital campus network system, such as Educational Management System,Teacher Information Platform and Network Teaching Platform. These systems has its ownsecurity policy, each user must remember multiple login account and password. Users to use adifferent application system, often repeated login, which affects not only the user experience,dispersed storage and management of information resources also enable information sharing,collaborative work is difficult to achieve. Meanwhile, gradually increased with the applicationsystem, not only to increase the system management and maintenance costs, but also makesthe application system authentication information vulnerable to illegal interception, therebyundermining the security and reliability of the system.In order to solve these problems, people introduce single sign-on technology to achieve"single sign on, multi-point access" effect. The user can access other authorization applicationsystem without having to log in again after the first successful login. The user need onlyremember a single sign on system certification account and password, then can enjoy theservices provided by multiple application systems, system administrators only need tomaintain a authentication information.Firstly, the paper analyzes the research background and significance of the digitalcampus single sign-on system, and study at home and abroad common commercial andopen-source single-point sign-on technology solutions and contrast. Secondly, the paperintroduces the theoretical knowledge of the single sign-on technology and analyzes theexisting JASIG-CAS single sign-on system. Followed by analyzes the project needs of thedigital campus single sign-on system DC-CAS, clarifies why i chose the open-sourceJASIG-CAS single sign-on system, summed up the advantages and deficiencies of theJASIG-CAS, and combined the actual demand of project and the advantage of domestic andinternational popular single sign-on solutions to improve the existing JASIG-CAS singlesign-on system. Finally, the paper designs and implements the DC-CAS system, and studyhow to integrate with existing application system to meet actual needs.
