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.

Abstract: An electronic control unit is connected to an in-vehicle network bus in an in-vehicle network system including a plurality of apparatuses that perform communication of frames via the bus. The electronic control unit includes a first control circuit and a second control circuit. The first control circuit is connected to the bus via the second control circuit over wired communication and/or wireless communication. The second control circuit performs a first determination process on a received frame received from the bus to determine the conformity with a first rule related to at least a reception interval, and, upon determining that the received frame conforms to the first rule, executes a predetermined process based on the content of the received frame. The first control circuit performs a second determination process on the received frame, received via the second control circuit, to determine the conformity with a second rule different from the first rule.

Abstract: An electronic control unit is connected to a network in an in-vehicle network system. The electronic control unit includes a first control circuit that operates on a first operating system and a second control circuit that operates on a second operating system. The first control circuit is connected to the network via the second control circuit. The second control circuit performs a first determination process on frames to determine conformity of the frames with a first rule. Upon determining that the frames conform to the first rule, the second control circuit transmits contents of the frames to the first control circuit. The first control circuit performs a second determination process on the contents of the frames to determine conformity with a second rule. The second rule is different from the first rule.

Abstract: A key management method serves as an electronic control unit (ECU) in an onboard network system having a plurality of ECUs that perform communication by frames via a network. The method includes storing, in a first-type ECU, a shared key to be mutually shared with second-type ECUs, and executing encryption processing regarding a framed transmitted or received via the network, based on the shared key. The method further includes executing, by the first-type ECU, inspection of a security state of the shared key stored by the second type ECUs in a case where a vehicle is in at least one of the following particular states, including immediately after the vehicle is not driving and is entering the accessory-on state, immediately after the vehicle is not driving and the vehicle is entering the accessory-off state, and immediately after the vehicle engine is started.

Abstract: A gateway device is connected via one or more networks to electronic controllers on-board a vehicle. The gateway device includes one or more memories, and circuitry that acquires firmware update information. The circuitry determines whether or not a first electronic controller satisfies a second condition based on second information about the first electronic controller, where the second information is whether the first electronic controller includes a firmware cache for performing a pre-update firmware cache operation. The circuitry also causes, when the second condition is not satisfied, the gateway device to execute a proxy process, where the gateway device requests the first electronic controller to transmit boot ROM data to the gateway device, creates updated boot ROM data with the updated firmware, and transmits the updated boot ROM data to the first electronic controller that updates the boot ROM and resets the first electronic controller with the updated firmware.

Abstract: An unauthorized activity detection method is provided in an onboard network system having multiple electronic units (ECU) that perform communication via a bus, such that an occurrence of an unauthorized state can be detected by monitoring frames transmitted over the bus. The unauthorized activity detection method determines, by a monitoring electronic control unit using unauthorized activity detection rule information indicating a first condition, whether or not a set of frames received from the bus satisfies the first condition. The first condition being a condition regarding a relation in content between a first frame having a first identifier and a second frame having a second identifier that differs from the first identifier. And the method further detects the occurrence of the unauthorized state in a case where the first condition is not satisfied.
