Open publisher page 0 citations

Abstract

This paper researches existing popular Single Sign-On model and Kerberos authentication protocol,and discusses the limits of Kerberos protocol in symmetric key technology,improves Kerberos protocol with the public key technology.Then it designs and realizes the agent-based single sign-on system,and by the second ticket method,ensures the safety of the SSO system.Meanwhile,the program has better performance in implementation,operating and management.
