Abstract:
1. A method for facilitating authentication in a wireless network comprising: (a) generating at a serving mobile network a visiting location register randomized authentication value; (b) transmitting the visiting location register randomized authentication value to a user device; (c) receiving an initial nonce value from the user device; (d) transmitting the initial nonce value to a home environment associated with the user device; (e) receiving an authentication vector from the home environment, the authentication vector including a subsequent nonce value derived from a first function that is shared by the user device and the home environment; (f) transmitting the authentication vector to the user device; (g) receiving a mobile station message authentication value from the user device, wherein the mobile station message authentication value is the result of a second function evaluated with the visiting location register randomized authentication value and the initial nonce value, and wherein the second function is shared by the user device and the home environment; and (h) transmitting an identifier corresponding to the user device, the visiting location register randomized authentication value, the mobile station message authentication value along with the initial nonce value to the home environment.
