Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHA
Field: Control (Instruments)
Classification: CPC B  G | IPC B  G

Claim 13:
14. A system comprising:
a logic device configured to perform operations comprising:
determine a threshold response time for a wireless communications device to process a challenge field;
send the challenge field to the wireless communications device;
receive a response to the challenge field from the wireless communications device within a time; and
authenticate the wireless communications device based on the response time being less than the threshold response time,
wherein determining the threshold response time comprises:
determining a benchmark response time for the wireless communications device to respond to the challenge field based on one or more conditions of the wireless communications device; and
setting the threshold response time to the benchmark response time, and

wherein the logic device is configured to determine the benchmark response time based on an amount of interference between the wireless communications device and the vehicle.
