Methods and apparatuses for application layer authentication of a data network based application using SIM function

摘要

Application layer authentication of a data-network based application makes use of a SIM function accessible to the application and telephone network authentication service accessible to a server to the application. For example, the application uses SIP (Session Initiation Protocol) for communication with the server and the authentication service is provided via a GSM based telephone network. In one implementation, a device (a "dongle") includes an authentication module, application software, and an interface for communicating with a remote server over a data communication network. The application software includes instructions for using the authentication module to authorize an application layer interaction with the remote server.
