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 service broker that is connected to each of a server unit and a client unit in a service offer system for offering a service from the server unit to the client unit by way of a service oriented communication includes: a communication controller that receives a frame for use in offer of the service, from the server unit or the client unit; and a service manager that determines whether a combination of a service identifier included in the frame received by the communication controller, an identifier indicating one of a transmission source and a destination of the frame, and a type of the frame is appropriate, and provides output of a result of the determination.

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.

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 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: In a fraud-detection method for use in an in-vehicle network system including a plurality of electronic control units (ECUs) that exchange messages on a plurality of networks, a plurality of fraud-detection ECUs each connected to a different one of the networks, and a gateway device, a fraud-detection ECU determines whether a message transmitted on a network connected to the fraud-detection ECU is malicious by using rule information stored in a memory. The gateway device receives updated rule information transmitted to a first network among the networks, selects a second network different from the first network, and transfers the updated rule information only to the second network. A fraud-detection ECU connected to the second network acquires the updated rule information and updates the rule information stored therein by using the updated rule information.
