摘要： A misuse detection method used in an electronic control unit in a vehicle network system including multiple electronic control units that communicate with one another through networks. The misuse detection method includes receiving a target data frame at one time point, and receiving a reference data frame at another time point different than the one time point. The misuse detection method further includes performing, as misuse detection for the target data frame based on a certain rule specifying a reception interval between the one time point at which the target data frame is received and the other time point at which the reference data frame is received, and determining the target data frame received is for misuse based on a length of the reception interval.

摘要： An anomaly detection electronic control unit (ECU) that detects unauthorized messages on a communication path is provided. An ECU that periodically transmits a first-type message including data to be monitored, and an ECU that periodically transmits a second-type message including data for comparison, are connected to the communication path. The anomaly detection ECU includes: a receiver that successively receives first-type and second-type messages; a processor that determines whether a first-type message received is normal or anomalous; and a transmitter that transmits a predetermined message in accordance with results of the determining. The determining is performed based on content of the first-type message, content of a second-type message last received at the time of receiving this first-type message, and at least one of content of a first-type message received further in the past than this first-type message, and content of a second-type message received further in the past than the second-type message last received.

摘要： A usual setting state in accordance with a current in-house state and a device state is selected using an acquired in-house state and a device state from a plurality of setting states classified in advance in accordance with in-house states and device states. When the selected usual setting state and the acquired setting state differ from each other, a first notification that notifies a user of the difference is performed and a state of an information terminal is transitioned to a state where an input for remotely controlling a second device can be accepted.

摘要： A gateway device for a vehicle network system installed in a vehicle is provided. The vehicle network system includes a network, an electronic control unit connected to the network, and the gateway device connected to the first network and configured to communicate outside the vehicle. The gateway device receives a first frame from outside the vehicle; determines whether or not the first frame is appropriate; generates a second frame when the first frame is not determined to be appropriate; and transmits the second frame to the network. The second frame includes control information and additional information based on content of the first frame. The control information restricts processing of the additional information included in the second frame by the electronic control unit, after the second frame is received by the electronic control unit.

摘要： A security device connected to a plurality of networks in a vehicle is provided. The security device determines, with regard to a frame received from a first network, whether to transmit a determination request for the frame outside the vehicle. The security device transmits the determination request outside the vehicle in a case where it is determined to transmit the determination request outside the vehicle, transmits, before obtaining a determination result from outside the vehicle in accordance with the determination request, the frame to a second network, and then obtains determination results from outside the vehicle in accordance with the determination request. The security device outputs presentation information in accordance with the determination result.

摘要： 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.

摘要： A navigation device (100) estimates a time when a user utilizing the navigation device (100) comes home, and transmits the estimated expected arrival time to a control device (203) in association with the user identifier of the user. In response to receiving the expected arrival times from a plurality of the navigation devices (100), the control device (203) transmits, to an air conditioner (201), a reservation instruction for setting the room temperature at the home to a predetermined target temperature by the estimated arrival time of the earliest user who is supposed to come home earliest. The air conditioner (201) is turned on in accordance with the transmitted reservation instruction among the users.
