MTC KEY MANAGEMENT FOR KEY DERIVATION AT BOTH UE AND NETWORK |
摘要 |
<p>There is provided a new IWF SMC procedure for establishing security association between an MTC UE (10) and an MTC-IWF (20). The MTC-IWF (20) sends to the UE (10) at least an algorithm identifier which instructs the UE (10) to select one of algorithms for deriving a root key (K_iwf). The UE (10) derives the root key (K_iwf) in accordance with the selected algorithm, and derives at least a subkey for checking the integrity of messages transferred between the UE (10) and the MTC-IWF (20) by using the derived root key (K_iwf). The UE (10) protects uplink messages transmitted to the MTC-IWF (20) with the derived subkey. The MTC-IWF (20) protects downlink messages transmitted to the UE (10) with the same subkey derived at a core network.</p> |
