Abstract


With the rapid development of information technology within companies and universities have deployed a large number of applications , these systems are often interrelated business authentication mechanism but are independent of each other . With the expansion of the number of systems , repeated login authentication information memory gave users bring inconvenience weakened the user experience , increase security risks ; authentication information redundancy increases the cost of management , not change synchronization more easily lead to data inconsistencies ; addition , the new system authentication module own development also increased the difficulty of development . Wide range of research and applications based on the needs of practical application , single sign-on technology . Single sign aimed at achieving a level of authentication systems integration, to provide users with a unified authentication entrance time you log in , the full Netcom line . Users simply enter the login information, you do not need to repeat the login permission to access different applications . Single sign-on technology research mostly around the principle and implementation of certification mechanism , ignored the construction of information management capabilities . Unified authentication and single sign-on system has two major tasks centralized information management , unified analysis and design improvement scheme was proposed based on the analysis of the existing technology , and Yale University, CAS Single Sign- model based on improved building simulation platform to achieve single sign-on system improvement scheme . The main work of this paper include the following aspects : first analyzed single sign commonly used model of the basic principles and implementation mechanisms , and elaborate system structures related to key technologies and knowledge . CAS single sign-on model selected on the basis of in-depth study and analysis of the strengths and weaknesses of the CAS and the lack of ideas to improve the crack for password may suffer violent attacks or remote password leak . Highlighted the weak problem of the CAS information management function to solve the problem , this paper using SSH framework for the development of information management platform for unified management of user information . Finally, the CAS model based on the improved program simulation tests show that the program has improved the feasibility of increased information management platform is fully functional , easy to use .
