    Abstract: A system and method is provided for authenticating a vehicle equipped with a passive keyless system. The method includes sending one or more initial challenge signal(s) from a vehicle module to a portable keyfob in response to a passive keyless start attempt of the vehicle, the initial challenge signal(s) being sent before a successful passive keyless start of the vehicle; sending one or more secondary challenge signal(s) from the vehicle module to the portable keyfob in response to at least one trigger event and after a successful passive keyless start of the vehicle; initiating an active authentication to confirm the presence of an authorized driver in the vehicle if a valid response to the secondary challenge signal(s) is not received by the vehicle module; and performing one or more remedial action(s) if a valid response to the active authentication is not received.

    Abstract: Systems and methods for theft deterrence of a vehicle are provided. Each of two or more immobilization point devices generate a random number and broadcasts it to all of the other immobilization points devices. Each of the immobilization point devices retains a local copy of its own random number and concatenates the local copy of its own random number with the random numbers of the other of the two or more immobilization point devices from the bus. From the random numbers broadcast on the bus, all of the random numbers are concatenated in a predetermined sequence to form a single challenge, which is transmitted to a remote transponder. Each of the immobilization point devices then compares a single response from the transponder to their local concatenation. When a specific portion of the response from the transponder matches a local concatenation, then enabling the function of the immobilization point device.
