  • Patent number: 11310070
    Abstract: A network hub is provided for an onboard network system. The onboard network system includes first and second networks for transmission of first-type and second-type frames following first and second communication protocols. The network hub includes a receiver that receives a first-type frame. A processor determines whether or not the first-type frame received by the receiver includes first information that is a base for a second-type frame to be transmitted to the second network, to obtain a determination result, and selects a port to send a frame based on the first-type frame based on the determination result. A transmitter sends the frame based on the first-type frame to a wired transmission path connected to the port selected by the processor based on the first-type frame received by the receiver.

  • Publication number: 20220116405
    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 and a second control circuit. The first control circuit is connected to the network via the second control circuit. The second control circuit performs a first determination process on a frame to determine conformity of the frame with a first rule. Upon determining that the frame conforms to the first rule, the second control circuit transmits the frame to the first control circuit. The first control circuit performs a second determination process on the frame to determine conformity of the frame with a second rule. The second rule is different from the first rule.

  • Patent number: 11303547
    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.

  • Patent number: 11296965
    Abstract: An abnormality detection method is provided. The abnormality detection method is for detecting an abnormality that may be transmitted to a bus in an on-board network system. The on-board network system includes a plurality of electronic controllers that transmit and receive messages via the bus in a mobility entity. In the abnormality detection method, for example, a gateway transmits identification information to a server and receives a response determining a unit time. An operation process is performed using feature information based on a number of messages received from the bus per the determined unit time and using a model indicating a criterion in terms of a message occurrence frequency. A judgment is made as to an abnormality according to a result of the operation process.

  • Patent number: 11283601
    Abstract: An update management method is used in an onboard network system having a plurality of electronic control units (ECUs) that performs communication via a network and connects to an external tool. The method includes a master ECU storing a shared key and an expiration date of the shared key. When the master ECU receives an update message, verifying update authority information indicating authority of the external tool, and determining whether or not a transmission of the update message is within a range of an authority of the external tool. The method also includes acquiring external point-in-time information, determining whether or not the external point-in-time information is before the expiration date, and transmitting an alert message prompting an update of the shared key. The ECUs are prioritized according to a designated level of authority, including chassis-related functions, body-related functions, safety/comfort functions, and telematics/infotainment functions.

  • Publication number: 20210306365
    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.

  • Publication number: 20210218739
    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.
