Abstract

The present invention is related to a wireless communication system. 3G UMTS mobile phone systems rely on a protected smart card called the UMTS integrated circuit card (UICC) that provides UMTS subscriber identity module (USIM) applications as a basis or root of various security measures protecting the communication path between the 3G mobile terminal and the UMTS wireless network (or UTRAN). Disclosed is a method by which the UICC exchanges information with a terminal, such as an Internal Key Center (IKC 1250) and a Bootstrapping Server Function (BSF 1270) enables a procedure where multiple local keys specific to applications and Network Application Functions (NAFs) (Ks_local) are used for authentication and to encrypt and decrypt messages.
