    Abstract: One commonality among most vehicular security attacks reported to date is that they ultimately require write access to the CAN bus. In order to cause targeted and intentional changes in the vehicle behavior, malicious CAN injection attacks require knowledge of the CAN message format. However, since this format is proprietary to OEMs and can differ even among different models of a single make of vehicle, one must manually reverse-engineer the CAN message format of each vehicle they target. To mitigate this difficulty, an automated CAN message translator is presented.

    Abstract: An in-vehicle network system includes a central ECU, which generates a control signal for a plurality of devices, and a plurality of zone ECUs, which relay a control signal from the central ECU. The plurality of devices include a first specific device (power window device, etc.), which is a device unrelated to drive control or the like of a vehicle, and which includes a sub controller (third signal processing unit, etc.) capable of activating an actuator based on an ON signal from at least one or some of the sensors. The first specific device is configured to control the actuator by using the sub controller in occurrence of abnormality of communication between the central ECU and the first specific device.
