Abstract:
Wireless network specific (WN-specific) key can be used to provide access protection over the radio access link. A WN-specific key may be associated with (or assigned to) a wireless network, and distributed to access points of the wireless network, as well as to user equipments (UEs) following UE authentication. The WN-specific key is then used to encrypt/decrypt data transported over the radio access link. The WN-specific key can be used in conjunction with the UE-specific keys to provide multi-level access protection. In some embodiments, WN-specific kays are shared between neighboring wireless networks to reduce the frequency of key exchanges during handovers. Service-specific keys may be used to provide access protection to machine to machine (M2M) services. Group-specific keys may be used to provide access protection to traffic communicated between members of a private social network.

Claim (Index 1):
A method for distributing keys in wireless networks, the method comprising:\n generating, by a wireless network (WN) key controller, a WN specific key, the WN specific key being assigned to a first wireless network; and distributing, by the key controller, the WN specific key to base stations in the first wireless network, wherein the WN specific key is configured to provide access protection over radio access interfaces established between the base stations in the first wireless network and user equipments (UEs) accessing the first wireless network.
