  • Patent number: 12261851
    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.

  • Patent number: 12225036
    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.

  • Patent number: 12206561
    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.

  • Publication number: 20250021643
    Abstract: Provided is a fraud detection rule updating method enabling the updating of rules that serve as the basis for detecting malicious frames as necessary in an on-board network system. In an on-board network system equipped with multiple electronic control units (ECUs) that communicate via buses and fraud detecting ECUs that determine, based on fraud detection rules, whether messages transmitted on the buses conform to the rules, a fraud detection rule updating method is used in which delivery data including updated fraud detection rules is received from a server external to the on-board network system, and if a certain update condition is satisfied, the fraud detection rules in a fraud detecting ECU are updated to the updated fraud detection rules.

  • Patent number: 12169708
    Abstract: A gateway device is connected to a plurality of electronic controllers on-board a vehicle. The gateway device acquires firmware update information, which includes at least a part of updated firmware to be applied to a first electronic controller, patch data, and information indicating where to apply the patch data. When the gateway device determines that the first electronic controller does not include a firmware cache for performing a pre-update firmware cache operation, the gateway device executes a proxy process. In this regard, the gateway device requests the first electronic controller to transmit boot ROM data to the gateway device, merges the patch data and existing firmware to create updated boot ROM data with updated firmware, and transmits the updated boot ROM data to the first electronic controller that updates the boot ROM data and resets the first electronic controller with the updated firmware.

    Abstract: In a data distribution method according to the disclosure, first authentication servers and a first data server belong to a first group, and second authentication servers and a second data server belong to a second group different from the first group. A first authentication server obtains first transaction data that includes a data obtaining request indicating a request for obtaining or referring to data pertaining to an apparatus, and records a block including the first transaction data into its distributed ledger belonging to the first group. A second authentication server obtains the first transaction data, and records the block including the first transaction data into a distributed ledger belonging to the second group. The first authentication server causes the first data server to transfer the data pertaining to the apparatus held therein to the second data server or to make such data available for reference by the second data server.
