Abstract: A method for use in a network system is provided. The network system includes a plurality of electronic controllers that transmits and receives, via a network, a plurality of frames. The plurality of frames includes at least one control frame that instructs predetermined control to an object of control. The method receives, sequentially, the plurality of frames from the network, and determines whether the predetermined control, instructed by the control frame received in the receiving, is to be suppressed, based on a set of frames received in the receiving. The set of frames is received in the receiving within a predetermined period preceding a time of reception of the control frame.

Abstract: A gateway device is connected via one or more networks to electronic controllers on-board a vehicle. The gateway device includes one or more memories, and circuitry that acquires firmware update information. The circuitry determines whether or not a first electronic controller satisfies a second condition based on second information about the first electronic controller, where the second information is whether the first electronic controller includes a firmware cache for performing a pre-update firmware cache operation. The circuitry also causes, when the second condition is not satisfied, the gateway device to execute a proxy process, where the gateway device requests the first electronic controller to transmit boot ROM data to the gateway device, creates updated boot ROM data with the updated firmware, and transmits the updated boot ROM data to the first electronic controller that updates the boot ROM and resets the first electronic controller with the updated firmware.

Abstract: A server apparatus receives a device ID indicating one electrical home appliance among one or more electrical home appliances and a gateway ID indicating that the one electrical home appliance belongs to a same owner, a same group, or a same home as the one or more electrical home appliances, determines whether or not the one electrical home appliance is a newly connected electrical home appliance, using a management database that manages device IDs indicating the one or more electrical home appliances and the gateway ID, and when it is determined made that the one electrical home appliance is a newly connected electrical home appliance, provides an information device, which is associated with the gateway ID and which differs from the one electrical home appliance, with notification information for confirming whether or not it is to be permitted to collect the log information from the one electrical home appliance.

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: 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.

Abstract: 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.

Abstract: 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.
