Abstract: An invalidity detection electronic control unit connected to a bus used by a plurality of electronic control units (ECUs) to communicate with one another in accordance with controller area network (CAN) protocol includes a receiving unit that receives a frame for which transmission is started and a transmitting unit that transmits an error frame on the bus before a tail end of the frame is transmitted if the frame received by the receiving unit meets a predetermined condition indicating invalidity and transmits a normal frame that conforms to the CAN protocol after the error frame is transmitted. Even when a reception error counter of the ECU connected to the bus is incremented due to the impact of the error frame, the reception error counter is decremented by the normal frame.

Abstract: An electronic control unit is connected to an in-vehicle network bus in an in-vehicle network system. The electronic control unit includes a first control circuit and a second control circuit. The first control circuit is connected to the in-vehicle network bus via the second control circuit over wired communication and/or wireless communication. The first control circuit performs a first determination process on a frame to determine conformity of the frame with a first rule. The second control circuit performs a second determination process on the frame to determine conformity of the frame with a second rule, and, upon determining that the frame conforms to the second rule, transmits the frame to the in-vehicle network bus.

Abstract: A fraud detection method for use in an in-vehicle network system including a plurality of electronic control units that communicate with one another via an in-vehicle network is provided. The method includes receiving at least one data frame sent to the in-vehicle network, verifying a specific identifier in the received data frame only when the received data frame is event-driven data and a state of a vehicle having the in-vehicle network system mounted therein is a predetermined state, detecting the received data frame as an authenticated data frame when the verifying is successful, and detecting the received data frame as a fraudulent data frame when the verifying fails. The predetermined state of the vehicle is the vehicle traveling.

Abstract: A method for dealing with unauthorized frames that makes it possible to take appropriate measures when an unauthorized data frame is detected in a vehicle network system is provided. A plurality of ECUs in the vehicle network system are connected to a bus used for communicating frames. In the method for dealing with unauthorized frames, if a misuse detection ECU that checks a frame appearing in the bus detects an unauthorized frame that does not comply with a certain rule and a certain prevention condition is satisfied, a process for preventing the plurality of ECUs from performing a process corresponding to the unauthorized frame is performed (an error frame is transmitted) or, if the certain prevention condition is not satisfied, the process is not performed.

Abstract: A security apparatus is provided that is connected to a bus. The security apparatus includes a receiver that receives a first frame from the bus, a memory that stores an examination parameter defining a content of an examination on the first frame, and processing circuitry that performs operations. The performed operations include first determining whether a predetermined condition is satisfied for the first frame. The performed operations also include, in a case where the first determining determined that the predetermined condition is satisfied, updating the examination parameter stored in the memory. The performed operations further include second determining whether the first frame is an attack frame based on the updated examination parameter stored in the memory.

Abstract: A gateway device is connected to a plurality of electronic controllers on-board a vehicle. The gateway device acquires firmware update information, which includes at least a part of updated firmware to be applied to a first electronic controller, patch data, and information indicating where to apply the patch data. When the gateway device determines that the first electronic controller does not include a firmware cache for performing a pre-update firmware cache operation, the gateway device executes a proxy process. In this regard, the gateway device requests the first electronic controller to transmit boot ROM data to the gateway device, merges the patch data and existing firmware to create updated boot ROM data with updated firmware, and transmits the updated boot ROM data to the first electronic controller that updates the boot ROM data and resets the first electronic controller with the updated firmware.

Abstract: An anomaly detection server is provided. The anomaly detection server is a server for counteracting an anomalous frame transmitted on an on-board network of a single vehicle. The anomaly detection server acquires information about multiple frames received on one or multiple on-board networks of one or multiple vehicles, including the single vehicle. The anomaly detection server, acting as an assessment unit that, based on the information about the multiple frames and information about a frame received on the on-board network of the single vehicle after the acquisition of the information about the multiple frames, assesses an anomaly level of the frame received on the on-board network of the single vehicle.
