AUTHENTICATION OF A SUBSCRIBER ON A PUBLIC NETWORK

摘要

A system and method for authenticating a subscriber to an application provider using the authentication services of the wireless network over which the connection is made. A unique client id is provided, over a public network, by a wireless device to an authenticator. An authentication challenge is returned to the wireless device, which generates a response in accordance with a shared secret key. The response is transmitted back to the authenticator, which, if it determines the response to be authentic, permits the wireless device to connect to the desired application provider. A method and system for obtaining non-repudiable authorization for a billing transaction, so that charges can be placed on a network access billing system by an outside service provider, is also disclosed.
