  • Communication system and information collection method executed in communication system
    Patent number: 10178094
    Abstract: An information collection method includes determining whether or not a vehicle satisfies predetermined conditions when a target device receives a test mode start request from an collection device, and when it is determined that the vehicle satisfies the predetermined conditions, starting the test mode. In the test mode, update of a predetermined counter is stopped. The collection device generates a first MAC based on the count value received from the target device and transmits an attack information acquisition request with the first MAC to the target device. If the attack information acquisition request with the first MAC is received from the collection device, the target device generates a second MAC based on the stopped count value, determines that the host device is normal in a case where the first MAC and the second MAC coincide with each other, and transmits the attack information to the collection device.
