Abstract
A terminal device seeking access to a mobile network retrieves a handset identifier identifying the terminal device and a cryptographic key for proving an identity of the terminal device from storage circuitry of the terminal device. The terminal device generates signature information by signing a block of information including the handset identifier using the cryptographic key. During a network connection process for negotiating access to the mobile network with a network control device, the terminal device communicates the signature information to the network control device.
