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: An anomaly detection electronic controller performs anomaly detection processing and is connected to a network, which a plurality of electronic controllers uses for communication. The anomaly detection electronic controller includes an anomaly detection processor that performs anomaly detection processing regarding a data frame. The anomaly detection controller also includes an anomaly detection processing requester that decides an anomaly detection processing timing when receiving the data frame, the anomaly detection processing timing being a reception timing of one or multiple fields in the data frame. The anomaly detection processor further performs the anomaly detection processing regarding the data frame at the anomaly detection processing timing decided by the anomaly detection processing requester.

Abstract: A fraud sensing method for use in an in-vehicle network system including a plurality of electronic control units that communicate with each other via a network includes detecting that a state of a vehicle satisfies a predetermined condition, and switching, upon detecting that the state of the vehicle satisfies the predetermined condition, an operation mode of a fraud-sensing electronic control unit connected to the network between a first mode in which a first type of sensing process for sensing a fraudulent message in the network is performed and a second mode in which the first type of sensing process is not performed.

Abstract: A program execution device capable of protecting a program against unauthorized analysis and alteration is provided. The program execution device includes an execution unit, a first protection unit, and a second protection unit. The execution unit executes a first program and a second program, and is connected with an external device that is capable of controlling the execution. The first protection unit disconnects the execution unit from the external device while the execution unit is executing the first program. The second protection unit protects the first program while the execution unit is executing the second program.
