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 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.
