    Abstract: A vehicle anomaly detection server includes: a communicator that communicates with a vehicle to receive a log of an in-vehicle network in the vehicle; a processor; and a memory including at least one set of instructions that, when executed by the processor causes the processor to perform operations including: selecting, when information indicating that an anomaly is occurring to a first vehicle among vehicles is obtained by the processor, an anomaly-related vehicle from among the vehicles based on the anomaly, the first vehicle being the vehicle that communicates with the communicator; transmitting, to the anomaly-related vehicle via the communicator, a first request to transmit a log of an in-vehicle network in the anomaly-related vehicle; and determining whether an anomaly is occurring to the anomaly-related vehicle, based on information indicated by the log transmitted from the anomaly-related vehicle and received by the communicator.

    Abstract: An anomaly detection device for detecting anomaly in frames flowing through an in-vehicle network system includes: an obtainer that obtains one or more frames; a first holder holding a first rule defining a rule indicating that when a frame satisfies a first condition based on a source or a destination, the frame is to be transferred; a first frame controller that transfers the one or more frames in accordance with the first rule; a second holder holding a second rule defining a rule indicating that a frame satisfying a second condition is to be determined as being anomalous; and a second frame controller that performs, in accordance with the second rule, an anomaly detection process on each of the one or more frames transferred by the first frame controller. When an anomalous frame is detected, the second frame controller provides or stores a detection result.

    Abstract: A statistical information generation device that generates statistical information from Ethernet frames on a mobility network includes: a transceiver that transmits and receives the Ethernet frames; and a statistical information generator that collects a plurality of Ethernet frames transmitted or received by the transceiver within a predetermined time period, and classifies, out of the plurality of Ethernet frames collected, Ethernet frames containing the same destination IP address, source IP address, destination port number, source port number, and protocol, and containing, in payloads, same identification information related to mobility control, into the same group, generates the statistical information for each group from the Ethernet frames classified into groups, and transmits the generated statistical information from the transceiver.
