Patent ID: 8503376

Claim:
A method for use by a wireless transmit/receive unit (WTRU) for establishing secure communication, the method comprising: establishing a secure tunnel, configured to enable a secure communication during a GBA_U process and a local-key set-up process, between an internal key center (IKC) and a UMTS Integrated Circuit Card (UICC), wherein the IKC is a trusted local entity residing on the WTRU, wherein the secure tunnel between the IKC and the UICC is a transport layer security-pre-shared key (TLS-PSK) tunnel established using a successfully authenticated pre-shared key set; and establishing a secure channel between the UICC and the IKC by performing the GBA_U process and the local-key set-up process over the established secure tunnel between the IKC and the UICC.
