摘要

The invention relates to a method for the extended authentication protocol based user authentication and a system for co-existence and the terminal authentication in a portable Internet system.; The present invention is an extended authentication protocol to co-exist with a mobile subscriber station, authentication in a portable Internet system: after completion of the in the (EAP Extensible Authentication Protocol) based user authentication method, (a) the mobile using the PKM protocol subscriber station authentication, a user sending the EAP request message sent for authentication by the mobile subscriber station; (B) receiving an EAP response message from the mobile subscriber station which receives the EAP request message transmission; And (c) separately and after the EAP request message sent and the EAP response messages are exchanged more than once, but characterized in that it comprises the step of transmitting a user authentication result message, and the user authentication method, the mobile subscriber station authentication It relates to a process for the extended authentication protocol based user authentication and a system for co-exist with a mobile subscriber station, authentication in a portable Internet system, characterized in that is carried out by.; According to the present invention, there is an effect that to be performed in a portable Internet system, the EAP-based authentication, the user separately after the base of the terminal authentication (Privacy Key Management) PKM be using existing methods and PKM EAP method without modification.
