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.

Abstract: An anomaly detection device (IDS ECU) includes a detection rule generator that monitors a communication establishment frame flowing over Ethernet in a communication establishment phase of service-oriented communication and that generates, for each communication ID, a detection rule including the communication ID written in the communication establishment frame and a server (or client) address written in the communication establishment frame; an anomaly detector that monitors a communication frame flowing over the Ethernet in a communication phase of the service-oriented communication and that, by referring to a detection rule that includes a communication ID written in the communication frame, detects the communication frame as an anomalous frame when a server (or client) address written in the communication frame differs from a server (or client) address included in the detection rule; and an anomaly notifier that provides a notification of an anomaly in response to the anomalous frame being detected.

Abstract: An abnormality detection method is provided. The abnormality detection method is for detecting an abnormality that may be transmitted to a bus in an on-board network system. The on-board network system includes a plurality of electronic controllers that transmit and receive messages via the bus in a mobility entity. In the abnormality detection method, for example, a gateway transmits identification information to a server and receives a response determining a unit time. An operation process is performed using feature information based on a number of messages received from the bus per the determined unit time and using a model indicating a criterion in terms of a message occurrence frequency. A judgment is made as to an abnormality according to a result of the operation process.

Abstract: An anomaly handling method using a roadside device is disclosed. The method includes receiving, from a 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 the roadside device and determining whether a distance between the location of the vehicle and the location of the roadside device 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 notification externally from the one 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 notification externally from the one vehicle.

Abstract: A network system includes a first network through which a frame of a first type is transmitted in accordance with a first communication protocol and includes a second network in which a frame of a second type is transmitted in accordance with a second communication protocol. A gateway device is connected to the first network and the second network. The gateway device sequentially receives frames of the first type from the first network and determines whether to transmit data regarding the received frames of the first type to the second network. The gateway device transmits, to the second network, a frame of the second type including data regarding a plurality of the frames of the first type determined to be transmitted to the second network when a condition relating to a number of frames of the first type received by the gateway device is satisfied.

Abstract: An anomaly detection system is on an in-vehicle network including: a first network connected to first devices that communicate using a first protocol; and a second network connected to second devices that includes a driving assistance controller communicates using a second protocol. The system includes: a communicator receiving, through the first network, first unit data including (i) source information indicating a source first device and (ii) second unit data including a data identifier; a database storing rule; and an anomaly determiner that determines whether the first unit data has anomaly by comparing the source information and the data identifier with the rule. Based on the rule, the first unit data is determined to have anomaly when the source first device is a sensing device and, according to the identifier, the second unit data is to be received by the controller.
