Problems solved by technology

[0013] However, the method for detecting duplication of the PSS using AUTHR and COUNT has a problem in that it increases traffic load between the PSS and the mobile telecommunication network due to comparing AUTHR and COUNT respectively in the mobile telecommunication network
Therefore, when the A-key and call history count COUNT are copied to the copied PSS, it is difficult to confirm whether the PSS is illegally copied
[0017] Second, when the original PSS is copied illegally, it is difficult to find out whether the copying was performed voluntarily by the user or by a malicious third party

Abstract

An apparatus and a 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.

Description

technical field [0001] The present invention relates to an apparatus and method for detecting duplication of portable subscriber stations in a portable internet system, and more particularly, to an apparatus and method for detecting duplication of portable subscriber stations in a portable internet system , wherein the illegal copy of the PSS can be detected even when the original Portable Subscriber Station (PSS) Medium Access Control (MAC) address, master key, and call history count are copied to the illegally copied PSS. Background technique [0002] Since the mobile telecommunication system using the cellular method was developed in the United States in the late 1970s, the Advanced Mobile Phone Service (AMPS), which is the first generation of the mobile telecommunication system, began to provide voice call services. In the mid-1990s, second-generation mobile telecommunication systems were commercialized, and International Mobile Telecommunications-2000 (IMT-2000), a thir...
