The message flow due to authentication, voice privacy, and signaling message encryption of two schemes that are expected to be incorporated in the EIA/TIA's cellular industry Interim Standard IS 41 Revision C are described and their impact on the traffic to network databases is studied.Abstract:
This paper describes the message flow due to authentication, voice privacy, and signaling message encryption of two schemes that are expected to be incorporated in the EIA/TIA's cellular industry Interim Standard IS 41 Revision C. We compare the two schemes with the use of a simple mobility model for users and study their impact on the traffic to network databases. Defining user mobility rate as the number of registrations per hour per user, we show that as the user mobility rate increases from roughly 0.5 to 15, the effectiveness of one of the schemes (the one that shares the shared secret data or SSD with the visited system) as compared to the other (the one that does not share it with the visited system) varies from about 66% improvement to about 30% degradation, clearly implying that the mobility characteristics of the user population dictate the choice of the authentication scheme.read more

Method for adaptively switching between pcs authentication schemes
TL;DR: In this article, the automaton used in the invention has 2n states, running from 0 to 2n-1, and switching between authentication schemes increases the efficiency of the overall authentication functions in the mobile communication system thereby reducing the number of database accesses needed to authenticate a registration or a call.
Patent
Method and apparatus for providing fraud protection mediation in a mobile telephone system
TL;DR: In this article, the authors proposed an improved home location register (HLR) that includes a fraud protection mediation module for use in a mobile telephone system, which operates in any one of the following situations: (1) a registration notice (REGNOT) is received by the HLR from a mobile switching center (MSC) currently serving a subscriber in a roaming area; (2) a qualification request (QUALREQ) is receiving by the hlr from a serving MSC for obtaining a subscriber's profile; and (3) the Hlr sends a
