Claim Text:
1. A method for binding a Universal Integrated Circuit Card (UICC) and a Machine Type Communication (MTC) device, comprising: when safe communication is required to be performed between an MTC device and a UICC, checking, by the MTC device, whether there is a key Ks_local shared by the MTC device and the UICC, when there is no key Ks_local shared by the MTC device and the UICC, starting, by the MTC device, a process of establishing a shared key Ks_local based on Generic Bootstrapping Architecture with UICC-based enhancements (GBA-U), and establishing on the UICC a binding relationship between the UICC and the MTC device to implement binding of the UICC and the MTC device, wherein the step of establishing the binding relationship between the UICC and the MTC device comprises: sending, by the MTC device, request information to the UICC to obtain at least a current B-TID and a life cycle of a key, wherein the request information comprises information on an identity of the MTC device; and when the UICC determines, according to the information on the identity of the MTC device, that no binding relationship between the UICC and the MTC device is stored on the UICC, establishing a key Ks_local shared by the UICC and the MTC device through the process of establishing a shared key Ks_local based on the GBA-U, and storing on the UICC the binding relationship between the UICC and the MTC device to implement the binding of the UICC and the MTC device.
