Abstract
A method of authenticating a device subscribed to a first wireless communication network on a second wireless communication network, the method including: deriving at a node within the first wireless communication network a set of one or more network keys for the second wireless communication network from one or more network keys of the first wireless communication network that uniquely identify the device within the first wireless communication network; communicating the derived set of one or more network keys to the device; storing a first copy of the derived set of one or more network keys within an identification module at the device and a second copy of the derived set of one or more network keys within a secure area of the device; and authenticating the device on the second wireless communication network using the second copy of the derived set of one or more network keys stored in the secure area of the device.
