Abstract: A vehicle monitoring apparatus includes: a first communicator that receives specifying information for specifying a target vehicle from a server; and an acquirer that acquires driving information from the target vehicle, the driving information being information regarding driving of the target vehicle specified by the specifying information received by the first communicator. The first communicator transmits the driving information acquired by the acquirer to the server. For example, the acquirer may acquire the driving information obtained from the target vehicle through communication.

Abstract: A method for use in a network communication system including a plurality of electronic controllers that communicate with each other via a bus in accordance with a Controller Area Network (CAN) protocol determines whether or not content of a predetermined field in a frame which has started to be transmitted meets a predetermined condition indicating fraud. In a case where the content of the predetermined field meets the predetermined condition, a frame including predetermined consecutive dominant bits for notifying an anomaly is transmitted before an end of the frame is transmitted. A number of times the frame including the predetermined consecutive dominant bits is transmitted is recorded for each identifier (ID) represented by content of an ID field included in a plurality of frames which has been transmitted. A malicious electronic controller is determined in accordance with the number of times recorded for each ID.

Abstract: An electronic control unit (ECU) is provided. The ECU is connected to a first network in an onboard network system. The onboard network system includes the first network and a second network. In the first network, first-type frames are transmitted following a first communication protocol. In the second network, second-type frames are transmitted following a second communication protocol. The first-type frame includes first information serving as a base for the second-type frame to be transmitted to the second network, and second information indicating that the first-type frame includes information that is to be transmitted to the second network. The ECU includes a generator that generates the first-type frame following the first communication protocol, and a transmitter that transmits, to the first network, the first-type frame generated by the generator.

Abstract: In an authentication method, a first controller generates a first group key, executes first mutual authentication with devices within a group, and shares the first group key with devices that have succeeded in the first mutual authentication. When a second controller joins the group, the first controller decides which coordinator manages a group key used in common. The first controller executes second mutual authentication with the coordinator, and shares the first group key with the coordinator when the second mutual authentication is successful. The coordinator performs encrypted communication within the group using the first group key, generates a second group key when the first group key valid time runs out and before updating the first group key, executes third mutual authentication with the devices and a third controller, and updates the first group key of the devices and the third controller that have succeeded in the third authentication.

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.

Abstract: A method used in an on-board network system, having electronic controllers that exchange messages and a fraud detecting electronic controller. The method includes determining whether a message transmitted conforms to fraud detection rules, and querying an external device whether there is delivery data for updating the fraud detection rules. When there is the delivery data for updating the fraud detection rules, receiving from an external device the delivery data, including updated fraud detection rules and network type information indicating a network type that the updated fraud detection rules are to be applied. The method also includes determining whether a vehicle in which the on-board network system is installed is running, and whether the network type information indicates a drive network that is connected to an electronic controller related to travel of the vehicle. When the network type information does not indicate the drive network, updating the fraud detection rules.

Abstract: A hub is connected to first and second networks where first-type and second-type frames are transmitted following first and second communication protocols. The hub sequentially receives each of the first-type and second-type frames, and stores data in first and second reception buffers. If the destination of data stored in the first and second reception buffers is the first network, the hub stores the data in a first transmission buffer. If the destination is the second network, the hub stores the data in a second transmission buffer. If the first transmission buffer is a priority transmission buffer, the hub transmits priority data in the first transmission buffer with priority over non-priority data in the second transmission buffer, which is a non-priority transmission buffer.
