Research Of Single Sign-On Technology

Under the environment of more applied system, the traditional authentication mechanism can easily lead to user's name and password loss and the name and password's management negligence, finally lead to the whole applied system be threatened, even be destroyed. In order to resolve the problem, the writer put forward the viewpoint of Single sign-on in the paper.Based on the concept, various models, work mechanism, standard solution project and the realistic solution project of Single sign-on, we put forward the solution project on the basis of PKI protocol to solve the problem of more system and more user's name for traditional models and analyze the Correlation between the Single sign-on and the AAA. Using the AAA technology to realize the united management, authentication and attestation of Single sign-on.In the paper the research works as follows:1. Research and Investigation the various models of Single sign-on now existed and analysis their advantages and disadvantages.2. Research and analysis the main solution project for Single sign-on and comparison their differences.
