Abstract:
Method for preventing security breaches via the two-thief method of attack of passive remote keyless entry systems for vehicles. The method involves the measurement of air travel time of the RF messages between the RKE fob and the vehicle. Multiple round trips between the fob and the vehicle are employed to magnify the distance covered by the messages and thereby allow accurate measurement of the air travel time.
