Abstract: A method for use in a network system is provided. The network system includes a plurality of electronic controllers that transmits and receives, via a network, a plurality of frames. The plurality of frames includes at least one control frame that instructs predetermined control to an object of control. The method receives, sequentially, the plurality of frames from the network, and determines whether the predetermined control, instructed by the control frame received in the receiving, is to be suppressed, based on a set of frames received in the receiving. The set of frames is received in the receiving within a predetermined period preceding a time of reception of the control frame.

Abstract: A risk information processing method is used in a risk information processing system that manages a degree of risk at a target spot at which a moving object is located. The method includes: receiving sensor data collected at each of two spots different from the target spot; determining a degree of risk of an event at each of the two spots from the sensor data collected at each of the two spots; storing, as risk information the determined degree of risk associated with each of the two spots; estimating first risk information associated with the target spot without sensor data of first event at the target spot, by using the stored risk information, the first risk information being a degree of risk of the first event at the target spot; and outputting information for the target spot based on the estimated first risk information.

Abstract: An anomaly detection device included in a communication network adopting a time-triggered protocol based on a time slot includes: a frame transceiver that receives frames; and an anomaly detector that detects an occurrence of an anomalous frame in accordance with a time slot among a plurality of time slots included in a cycle and the number of repeated cycles of the cycle for each frame. The anomaly detector detects an occurrence of an anomalous frame by verifying a statistic on the frames received while the cycle is repeated a predetermined number of times, which is at least once, against a rule indicating a reference range of the statistic.

Abstract: A gateway device for a vehicle network system is provided. The vehicle network system includes a first network, a second network, a first electronic control unit connected to the first network, a second electronic control unit connected to the second network, and the gateway device connected to the first network and the second network. The gateway device receives a first frame transmitted to the first network by the first electronic control unit; determines whether or not the first frame is appropriate; generates a second frame when the first frame is not determined to be appropriate; and transmits the second frame to the second network. The second frame includes control information and additional information based on content of the first frame. The control information restricts processing of the additional information included in the second frame by the second electronic control unit.

Abstract: A gateway device for a vehicle network system installed in a vehicle is provided. The vehicle network system includes a network, an electronic control unit connected to the network, and the gateway device connected to the first network and configured to communicate outside the vehicle. The gateway device receives a first frame from outside the vehicle; determines whether or not the first frame is appropriate; generates a second frame when the first frame is not determined to be appropriate; and transmits the second frame to the network. The second frame includes control information and additional information based on content of the first frame. The control information restricts processing of the additional information included in the second frame by the electronic control unit, after the second frame is received by the electronic control unit.
