APPLICATION AUTHENTICATION IN WIRELESS COMMUNICATION NETWORKS

摘要

A method in wireless communications devices including generating a lower layer cipher key from a lower layer access key stored on the wireless communications device, for example, on a smart card, and then generating a higher layer authentication key (210) from the lower layer cipher key (230). The higher layer authentication key is also generated at a network entity and delivered to an authentication and authorization server. An application server authenticates subscriber device service requests with the authentication and authorization server using the higher layer authentication key.
