Implementation for federated Single Sign-on based on network identity

This paper proposes a secure and fast one-pass authentication procedure bundling NACF and IMS authentications under enhanced security. Proposed scheme considerably reduces the complexity of authentication procedure compared to existing approaches. This paper mainly focuses on method authenticating federation Single Sign-on (SSO) about application service and IMS service based on network id in the Next Generation Networks (NGN) environment. Federation SSO is the one method of Single Sign-on which user can select the subscription of federation operator in real-time. For comprising this system, we need Service Control Function (SCF), Network Access Control Function (NACF), Web Application Service Control Function (WASCF) and NGN Terminal Function (NTF). Currently, certificate is used in internet banking. But, if real-time security monitoring tool is not operated, the exposure of certificate is very easy. For One Time Password (OTP) terminal case, it is lack with compatibility. If PC is detected by hacker, there is a problem. Through this paper, we propose the procedure to intercept originally the exposure of personal information in the internet. Therefore we suppose the procedure supporting Federation SSO authentication based on network id. That is, authentication system of reliable network operator can authenticate web application service (internet banking and so on).
