The disclosure discloses a method and apparatus for binding a UICC and an MTC device to solve a problem of restriction to a binding relationship imposed by a life cycle of a pre-shared key Ks_local when binding of the MTC device and the UICC is implemented by way of GBA-U. With the disclosure, after a binding relationship between the MTC device and the UICC is established on the UICC, when a stored key shared by the MTC device and the UICC expires, a key Ks_local shared by the UICC and the MTC device can be re-established through a process of establishing the shared key Ks_local based on the GBA-U according to the established binding relationship, such that the binding relationship between the UICC and the MTC device is not restricted by the life cycle of a shared key Ks_local. |
