Design of PKI and Password Protected Card-Based Double Authentication Single Sign-On System

To design a more secure and efficient single sign-on system, this paper analyzed the popular single sign-on systems and then introduced the original design model of SSO, due to the limitation of the original design model, we present the proposed design model named as PKI and password protected card-based single sign-on system (3PC-SSO), which combines the advantages of Kerberos and PKI-based single sign-on system. Finally, we analyze two problems of 3PC-SSO and discuss the future work.
