Abstract:
A method, an apparatus, and a computer program product for wireless communication are provided. A method includes transmitting a request to a serving network with a nonce and a signature request directed to a network function of the serving network, receiving a response to the request from the serving network, and authenticating the serving network based on the signature of the network function. The nonce may provide replay protection. The response may include a signature of the network function. The request sent to the serving network may include a radio resource control (RRC) message or a tracking area update (TAU) request. The serving network may be authenticated using a trusted third party to verify a certificate associated with the serving network.

Claim (Index 13):
An apparatus adapted to operate as a network function in a serving network, comprising:\n secured storage adapted to store an operator-signed certificate; and a processing circuit configured to:\n receive a first message from a wireless communication device after the wireless communication device has authenticated the serving network through a secured connection with a home network, wherein the first message is directed to the network function and includes a nonce and a signature request; \n generate a signature using the operator-signed certificate maintained in the secured storage; and \n transmit a second message to the wireless communication device, wherein the signature is attached to the second message, wherein the wireless communication device is configured to use the signature to verify authenticity of the serving network based on a list of trusted networks maintained by the wireless communication device.
