1. A method for authentication of a mobile device in a wireless communication network comprising the steps of:
- sharing a secret between the mobile device and a first device;
requesting by the mobile device a connection to a second device;
determining whether the mobile device can connect to the second device by the second device;
(i) concurrently sending a challenge to the mobile device and sending the challenge and an identity of the mobile device to the first device;
(ii) receiving a first authentication code from the mobile device based on the shared secret at the mobile device in response to the challenge;
(iii) receiving a second authentication code from the first device based on the shared secret at the first device in response to the challenge;
(iv) comparing the first authentication code with the second authentication code; and
(v) authenticating the mobile device at the second device when the first authentication code matches the second authentication code.

Abstract
A method and apparatus for authentication in a wireless communication network is disclosed. A secret is shared between a mobile device and a home device. When a mobile device requests a connection to a remote device and the remote device does not have knowledge of the shared secret, the remote device determines whether the mobile device can connect to the remote device by concurrently sending a challenge to the mobile device and the home device. The remote device then compares the responses from the mobile device and the home device.

11. A method for authentication of a mobile device in a wireless communication network comprising the steps of:
-
sharing a secret between the mobile device and a first device; requesting by the mobile device a connection to a second device wherein the second device does not have knowledge of the shared secret; determining by the second device whether the mobile device can connect to the second device by a) concurrently sending a challenge to the mobile device and sending the challenge and an identity of the mobile device to the first device and b) comparing responses to the challenge from the mobile device and the first device; and setting up confidential communications between the mobile device and the second device when the responses to the challenge from the mobile device and the first device match, wherein the response from the mobile device comprises;
a first keying material calculated at the mobile device based on a second shared secret at the mobile device;wherein the response from the first device comprises a second keying material calculated at the first device based on the second shared secret at the first device; and further wherein the confidential communications between the mobile device and the second device is initiated at the second device when it determines that the first keying material equals the second keying material. - View Dependent Claims (12, 13, 14, 15)

16. A system for authentication of a mobile device to a remote device in a wireless communication network comprising:
-
means for sharing a secret between the mobile device and a home device; means for requesting by the mobile device a connection to the remote device wherein the remote device does not have knowledge of the shared secret; and means for determining by the remote device whether the mobile device can connect to the remote device by concurrently sending a challenge to the mobile device and sending the challenge and an identity of the mobile device to the home device, comparing a first authentication code based on the shared secret included in a response to the challenge from the mobile device and a second authentication code based on the shared secret included in a response to the challenge from the home device, and authenticating the mobile device at the remote device when the first authentication code matches the second authentication code.
