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: 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: A vehicle anomaly detection server includes: a communicator that communicates with a vehicle to receive a log of an in-vehicle network in the vehicle; a processor; and a memory including at least one set of instructions that, when executed by the processor causes the processor to perform operations including: selecting, when information indicating that an anomaly is occurring to a first vehicle among vehicles is obtained by the processor, an anomaly-related vehicle from among the vehicles based on the anomaly, the first vehicle being the vehicle that communicates with the communicator; transmitting, to the anomaly-related vehicle via the communicator, a first request to transmit a log of an in-vehicle network in the anomaly-related vehicle; and determining whether an anomaly is occurring to the anomaly-related vehicle, based on information indicated by the log transmitted from the anomaly-related vehicle and received by the communicator.

Abstract: A fraud detecting method for use in an in-vehicle network system including a plurality of electronic control units that communicate with each other via a network includes detecting whether a state of a vehicle satisfies a first condition or a second condition, and switching, upon detecting that the state of the vehicle satisfies the first condition or the second condition, an operation mode of a second electronic control unit connected to the network. A first mode in which a first type of detecting process for detecting a fraudulent message in the network is performed is switched to a second mode in which the first type of detecting process is not performed upon detecting that the state of the vehicle satisfies the first condition. Moreover, the second mode is switched to the first mode upon detecting that the state of the vehicle satisfies the second condition.

Abstract: An authentication method is used by an automated driving system that includes a vehicle and an external device, the external device communicating with the vehicle to cause the vehicle to implement automated driving. The vehicle holds a first certificate that certifies validity of the vehicle. The external device holds a second certificate that certifies validity of the external device. The authentication method includes: validating a third certificate that certifies validity of a combination of the vehicle and the external device, in accordance with a result of device authentication performed between the vehicle and the external device by reference to the first certificate and the second certificate.

Abstract: An information management method collects log information of one or more home electrical apparatuses corresponding to service providers. Display screen data is generated which indicates a status of the log information. The display screen data includes groups of information which each contain information on an apparatus, a service provider corresponding to the apparatus, and log information output from the apparatus. Provision of the log information of each group is individually selectable. The display screen data is provided via a network to a display terminal that performs access to a server device. Information is received from the display terminal, which indicates that selection on whether or not provision of the log information is performed. Provision of the log information is not performed on the selected group when a determination is made that refusal of provision of the log information on the selected group is performed.

Moreover, in the second mode, a second type of detecting process having a different degree to which a fraudulent message is detectible than the first type of detecting process is performed.

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.
