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.

Security processing method and server

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.

Information management method

In an anomaly determination method for determining an anomaly in a received message, a plurality of messages which include messages that are periodic and each of which includes a first field having a fixed value and a second field having a variable value are each received as the received message, and one of a plurality of combinations to be used for determination each of which includes at least one of a plurality of anomaly determinations including an anomaly determination utilizing a reception timing based on the periodicity or the number of received messages, an anomaly determination utilizing the first field, and an anomaly determination utilizing the second field, is selected according to one or more criteria among available execution time of the anomaly determination method, a load amount, a data amount, and the number of messages.

Anomaly determination method, anomaly determination device, and recording medium

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.

Gateway device, in-vehicle network system, and firmware update method

A fraud detection method includes: determining whether a period of a message repeatedly transmitted in an in-vehicle network is anomalous; detecting whether arbitration occurs when the message is transmitted in the in-vehicle network; and determining that the message is an anomalous message, in the case where the period of the message is anomalous and no arbitration occurs when the message is transmitted in the in-vehicle network.

Fraud detection method, fraud detection device, and recording medium

A gateway that notifies a fraud detection server located outside a vehicle of information about an in-vehicle network system including an in-vehicle network includes: a priority determiner that determines a priority using at least one of: a state of the vehicle including the in-vehicle network system; an identifier of a message communicated on the in-vehicle network; and a result of fraud detection performed on the message; a frame transmitter-receiver that transmits and receives the message communicated on the in-vehicle network; a frame interpreter that extracts information about the in-vehicle network based on the message received by the frame transmitter-receiver; and a frame uploader that notifies the fraud detection server of notification information including the priority and the information about the in-vehicle network.

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.

A reference message determining method is used in unauthorized communication detection in an onboard network system that is executed by an information processing system including at least one memory. The onboard network system including a network and one or more electronic control units connected to the network. The method includes executing unauthorized activity detection for determining whether or not a message received from the network is an attack message. A message that could not be determined to be unauthorized is regarded as a gray message. The method also includes determining whether or not the gray message is unauthorized again at a predetermined timing. In a case where the gray message is determined to be an attack message in the unauthorized-activity-detection executing operation, a communication pattern is identified based on information relating to the gray message and information relating to the plurality of the received messages previously determined as unauthorized.
