Abstract: An apparatus and method for detecting duplication of a portable subscriber station (PSS) in a portable Internet system are provided. A master key of a PSS and a master key of an AAA server are identically updated whenever the PSS succeeds in authentication. It is possible to determine whether the PSS is duplicated or not by comparing the master key of the PSS with the master key of the AAA server during an authentication procedure. In addition, it is possible to find out whether duplication for the corresponding PSS is made by a user's own volition or by a third party by additionally performing an authentication procedure which requires an input of a password for a PSS which is doubted as duplicated.

Abstract: Disclosed are an apparatus and a method for processing authentication using Extensible Authentication Protocol-Authentication and Key Agreement (EAP-AKA) in a non-Universal Subscriber Identity Module (USIM) terminal without a USIM card. According to the present invention, although the USIM card used for user authentication function is absent, the secret value that used to be stored in the USIM card for user authentication is directly stored in the non-USIM terminal. Therefore, both a user password and a secret value are applied for EAP-AKA authentication of the terminal and the user and user authentication problems caused by lack of the USIM card can be overcome.
