Secure Remote USIM (Universal Subscriber Identity Module) Card Application Management Protocol for W-CDMA Networks

Abstract

Even though 3GPP presents a secure remote card application protocol through W-CDMA networks, it is unstable in terms of security and key management. For solving the weakness of 3GPP, we propose a WPKI (WAP Public Key Infrastructure) based secure remote USIM (Universal Subscriber Identity Module) card application management protocol, which is used in W-CDMA networks.

“…US1M is a combination of the traditional SIM card that is loaded with the user information and Ulee (Universal Ie card) module . USIM is capable of doing various SIM functions and of Ulf'C which can store a lot of application [10]. As an important and mobile part, Ulee is mainly used to store user information such as authenticate, charge and so on for certain applications.…”
