Title: DETECTOR, DETECTION METHOD AND DETECTION PROGRAM
Abstract:
A detector mounted in a vehicle for detecting false communication in a car-onboard network. The detector is provided with: a monitoring unit for monitoring first information, transmitted in the car-onboard network, that indicates a state or control relating to the vehicle; a prediction unit for predicting, on the basis of the first information monitored by the monitoring unit, the occurrence of second information in the car-onboard network that indicates a state or control relating to the vehicle; and a determination unit for determining, when the second information is transmitted in the car-onboard network, whether or not the transmitted second information is false on the basis of the prediction result of the prediction unit.
