  • Dynamic relay attack prevention using time of flight and RF fingerprinting
    Patent number: 11254288
    Abstract: Controlled access to a vehicle is provided. Whether time of flight (ToF) between an access device and a controller of the vehicle indicates a relay attack is identified. Whether a radio frequency (RF) fingerprint of the access device indicates a relay attack is identified. Responsive to the RF fingerprint but not the ToF indicating a relay attack, the ToF determination is retried. Passive access is allowed to the vehicle responsive to the retried ToF again indicating no relay attack.
