A method in which a terminal performs sign-on in a communication system according to the present invention comprises: a step of transmitting information including a user identifier to a relay part (RP); a step of receiving, from said RP, a re-direct request message including a request for an open ID authentication; and a step of verifying the validity of said RP based on the re-direct message. The present invention relates to a method and an apparatus for safely and efficiently supporting a single sign-on procedure performed by a terminal during communication between the terminal and a network in case of supporting generic bootstrapping architectures, associated protocols and other security-related protocols and an open ID in an evolved mobile communication system including 3GPP EPS. According to the present invention, security-related procedures are performed to enable a terminal to safely perform a single sign-on procedure in a mobile communication environment. Thus, the method and apparatus of the present invention provide advantages in that the terminal may perform single sign-on (referred to as "SSO" hereinafter) in a security environment, so that a user may access all of the permitted resources and communicate after being once logged on a network. |
