Recently, amplification attack has been used to penetrate authentication system of many vehicles from diverse manufacturers. Usually, two devices are used to launch amplification attack between a remote key and a car. One of them sniffs an authentication signal from a key, and sends it to the other device after amplification. Since the key can communicate with the corresponding car due to signal amplification by the hacker, the hacker can open a car even though the key is separated from the car by a long distance.
Thus, two authentication mechanisms are proposed to resolve this amplification attack. If we know the geographic proximity of a key to the corresponding car accurately, then the amplification attack might be resolved by denying authentication when the key is away from the car by a long distance. In the first mechanism, we use GPS and magnetic sensors to check the proximity between the key and the car. In the second mechanism, we use the list of Access Points (APs) measured by the key and that measured by the car to check the proximity. The performance of those two mechanisms are evaluated through simulation and experiment. The AP-based mechanism exhibited a better performance in terms of error probability.
