  Abstract

GSM(Global System for Mobile communications) provides mobile users with portability and convenience as the most popular standard for mobile phones in the world. However, GSM system has the problem that can't normally authenticate a user by the exposure of IMSI(International Mobile Subscriber Identity) of Ms(Mobile station) during the user authentication procedure. In this paper, we propose secure user authentication by preventing the exposure if IMSI via transfer the encrypted IMSI from the HLR(Home Location Register) and making the only network entities verified from the HLR use the IMSI value, as the modified mechanism based on the original user authentication protocol to solve this authentication problem. Also the proposed mechanism provides fast user authentication without changing the architecture between new VLR and old VLR in the original GSM user authentication protocol as well as user's anonymity by using a temporary ID.
