Abstract

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.
