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.
