Abstract—Hacking and threats are increasing day by day. Authentication of mobile subscribers and network is an important criterion to the researchers. Now mobile communication system (3-G or advanced) has been developed to speed up the data communication. 3-G mobile communication uses two different switching techniques: circuit switching for voice and low speed data communications, and packet switching mainly for data communication, but can afford voice communication like VoIP (Voice Over Internet Protocol), video telephony, multimedia service etc. Generally high speed data communication uses packet switching process through PDSN (Packet Data Serving Node) servers. In circuit switching (3-G network), authentication is mutual where both MS and MSC or network authenticate each other, but in packet switching only network (servers in PDSN) examines the authenticity of MS. In this paper, I propose a mutual authentication tracking loop technique that verifies the authenticity of the subscriber as well as the network by subscriber’s password, SIM and biometric property of the subscriber. Two biometric parameters are used in which one biometric parameter is stored in SIM. The other biometric parameter, taken as voice frequency for the common words spoken by a subscriber, called certified document (CD), is stored at the server (PDSN or MSC). An algorithm is developed by these four entities to check this authentication process at the starting time of a call as well as a regular time intervals (say 10~20 secs) while the call is progressing, named mutual authentication tracking loop technique for 3-G mobile communications.
Index Terms—Biometric property, Certified Document, Voice frequency, Clapping sound, Flipping sound, Mutual Authentication tracking, Packet Switching, Password, SIM.
