Abstract:
1. A method for secure wireless communication, the method comprising: receiving, at a user equipment, a handover nonce key protected by a secure protocol from a core component of a network, the secure protocol preventing the handover nonce key from being learned by base stations supported by the core component of the network; sending a measurement report to the source base station after the receiving, at the user equipment, of the handover nonce key from the core component of the network; receiving, at the user equipment, a handover command from a source base station, the handover command including a target base station identifier identifying a target base station, the target base station being a base station targeted to provide services to the user equipment that is supported by the source base station; deriving encryption keys using the received handover nonce key and the target base station identifier; and communicating with the target base station based on the derived encryption keys and the target base station.
