A mobile trusted platform (MTP) configured to provide virtual subscriber identify module (vSIM) services is disclosed. In one embodiment, the MTP includes: a device manufacturer-trusted subsystem (TSS-DM) configured to store and provide credentials related to a manufacturer of the MTP; a mobile network operator-trusted subsystem (MNO-TSS) configured to store and provide credentials related to a mobile network operator (MNO); and a device user/owner-trusted subsystem (TSS-DO/TSS-U) configured to store and provide credentials related to user of the MTP. The TSS-MNO includes a vSIM core services unit, configured to store, provide and process credential information relating to the MNO. The TSS-DO/TSS-U includes a vSIM management unit, configured to store, provide and process credential information relating to the user/owner of the MTP. The TSS-DO/TSS-U and the TSS-MNO communicate through a trusted vSIM service.

Virtual subscriber identity module

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) and a Bootstrapping Server Function (BSF) 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.
