A process is provided in which a first device, e.g., a hub device of a home network, is temporarily provided with a SIM to store a challenge-response, and thereafter the first device uses the stored challenge-response to interrogate a second device, e.g., a mobile telephone, to authenticate that the second device now has the SIM with which the first device was previously provided. A further process is provided in which the second device authenticates that the first device previously had access to the SIM by verifying that a response from one or more challenge-response pairs provided by the first device to the second device is the same as a response received by the second device from the SIM when the second device interrogates the SIM with the challenge of the challenge-response pair received earlier from the first device. |
