Abstract
A vehicle security system uses a portable device such as a pocket PC or PDA. When the device is inserted in a cradle in the vehicle, it communicates with the on-board computer to obtain the vehicle identity. The device then sends a request message, containing the vehicle identity and device identity, to a remote authentication server. The authentication server performs a number of checks, including checking that the device is authorized for use with this vehicle, and returns a response to the device. If the authentication is successful, the device allows the vehicle to be started. If the response from the authentication server is delayed, the vehicle may be started, but if the authentication check then fails, an on-line check will be compulsory the next time an attempt is made to start the vehicle.
