Clone terminator: an authentication service for advanced mobile phone system

In this paper we propose an innovative centralized, proof-by-knowledge authentication service by using IN to terminate the clone problem in AMPS. With our proposed service, the authentication information of mobile stations is transmitted on the control channels and voice channels separately and asynchronously. Since the number of voice channels is relatively larger than the number of control channels, the authentication information is hard to eavesdrop. In addition, the voice channels have the permutation property to protect from secure attack. Therefore, the mobile stations cannot be purposely duplicated by eavesdropping messages or copying the serial numbers and mobile identification numbers transmitted by the control channels on the air. Furthermore, the security of the proposed service is completed by the combination of mobile services and IN services
