  • Publication number: 20240053977
    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.

  • Patent number: 11895146
    Abstract: Provided is an infection-spreading attack detection system and method, as well as a program enabling an occurrence of an infection-spreading attack to be detected with high accuracy. A first feature amount is calculated based on traffic information on a packet transferred by a transfer device, and M partial address space(s) are identified to be a monitoring target based on the first feature amount. A second feature amount is calculated for each of the M partial address space(s) based on the traffic information related to the M partial address space(s). Abnormality detection determination is performed on each of the M partial address space(s) based on the second feature amount. Whether the infection-spreading attack has occurred is determined by evaluating M determination results.

    Abstract: A gateway device is connected via network(s) to electronic controllers on-board a vehicle, where at least one of the electronic controllers is implemented in a virtual machine. The gateway device includes one or more memories, and circuitry that acquires firmware update information. The circuitry determines whether a first electronic controller satisfies a second condition based on second information, which 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.

  • Publication number: 20230390764
    Abstract: The present disclosure provides a microchannel device that has a channel sandwiched between channel walls formed in an inside of a porous substrate, wherein the channel wall contains a thermoplastic resin and a colorant, and wherein an abundance ratio of the colorant is higher in the porous substrate surface area of the channel wall than in an internal area of the channel wall. In the configuration of the present disclosure, since more of the colorant exist on the surface side of the porous substrate in the channel wall, the visibility of the channel is increased, and in addition, since the amount of the colorant in the internal portion of the channel wall is small, the elution of the ions contained in the colorant into the specimen is suppressed, and the measurement accuracy is increased.

  • Publication number: 20230370480
    Abstract: 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.
