Abstract:
The disclosure relates to a security method in a radio access network system. A shared secret key is stored in both a user device and a core network system. A further secret key is received from the core network system, wherein the further secret key has been derived using the shared secret key stored in the core network system. One or more values are provided over the radio interface to the user device to derive the further secret key in the user device from at least the shared secret key stored in the user device and one or more of the one or more values provided over the radio interface. An authentication procedure and/or a key agreement procedure is performed for the user device over the wireless radio interface using the received further secret key in the radio access network system and the derived further secret key in the user device.

Claim (Index 4):
A subscriber hardware module for use in a user device, wherein the user device is configured for operating within a radio access network system the radio access network system comprising one or more base stations providing a wireless radio interface for at least one user device, wherein a shared secret key is stored in both the user device and a core network system of a telecommunications network, wherein the subscriber module is configured to:\n store the shared secret key and for deriving the further secret key; receive a first authentication request causing the subscription module to derive the further secret key; and receive a second authentication request, subsequent to the first authentication request, causing the subscription module to use the further secret key for at least one of a local authentication procedure or a local key agreement procedure, and wherein the user device is configured to perform at least one of the local authentication procedure or the local key agreement procedure using the derived further secret key.
