Mobile user authentication over WIFI using IPX networks

Abstract:

A client device accesses an online system using an authentication process when it is connected to a public network and not a private network. The client device requests access using an authentication broker via the public network. The authentication broker determines an authentication system and transmits identification information for the client device to the authentication system via the private network. The authentication broker receives an authentication vector generated by the authentication system via the private network, and receives a verification response from the client device via the public network. The verification response corresponds to a verification challenge generated based on the authentication vector by the authentication broker. The authentication broker determines the client device is authorized to access the online system based on the authentication vector and verification response and transmits an authorization to the client device via the public network allowing access to the online system.
