Abstract: A security apparatus is provided that is connected to a bus. The security apparatus includes a receiver that receives a first frame from the bus, a memory that stores an examination parameter defining a content of an examination on the first frame, and processing circuitry that performs operations. The performed operations include first determining whether a predetermined condition is satisfied for the first frame. The performed operations also include, in a case where the first determining determined that the predetermined condition is satisfied, updating the examination parameter stored in the memory. The performed operations further include second determining whether the first frame is an attack frame based on the updated examination parameter stored in the memory.

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.

Abstract: An electronic control unit is connected to a network in an in-vehicle network system. The electronic control unit includes a first control circuit and a second control circuit. The first control circuit is connected to the network via the second control circuit. The second control circuit performs a first determination process on a frame to determine conformity of the frame with a first rule. Upon determining that the frame conforms to the first rule, the second control circuit transmits the frame to the first control circuit. The first control circuit performs a second determination process on the frame to determine conformity of the frame with a second rule. The second rule is different from the first rule.

Abstract: In an anti-fraud control system, a first error monitoring device includes a first frame transmitting and receiving unit that receives a frame flowing on the on-board network; and a first error detector that causes transmission of an error notification frame for notifying of an occurrence of an error in the frame when detecting the occurrence of the error in the frame received by the first frame transmitting and receiving unit. Each of second error monitoring devices includes: a second frame transmitting and receiving unit that receives the error notification frame; and a second error detector that regards, as a frame to be invalidated, the frame subjected to the error and included in the received error notification frame, and shifts the second error monitoring device to an invalidation mode for invalidating reception of subsequent frames, if no error is detected in an own branch with respect to the frame.

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.

Abstract: An anomaly handling method using a device installed outside of a vehicle is disclosed. The method includes receiving, from the vehicle, an anomaly detection notification, which includes level information indicating a level affecting safety, and a location of the vehicle. The method also includes obtaining a location of another vehicle and determining whether a distance between the location of the vehicle and the location of the other vehicle is within a predetermined range. When the distance is within the predetermined range and is shorter than a first predetermined distance, not changing the level information and transmitting the received anomaly detection information to the other vehicle. When the distance is within the predetermined range and is longer than or equal to the first predetermined distance, changing to decrement a level indicated by the level information, and transmitting changed anomaly detection information to the other vehicle.
