    Abstract: An anti-fraud method for use in an in-vehicle network system including a plurality of electronic control units that exchange data frames, each having added thereto a message authentication code (MAC), via at least one bus includes: receiving a data frame transmitted on the bus; generating a first MAC by using a MAC key and a value of a counter that counts the number of times a data frame having added thereto a MAC is transmitted; in a case where the verification has failed, (i) generating as second MAC by using an old MAC key; (ii) re-verifying that the received data frame has added thereto the generated second MAC; transmitting, in a case where the re-verification has succeeded, via the bus a key-update frame indicating a request for updating the MAC key; and updating the MAC key in response to the transmission of the key-update frame.

    Abstract: An electronic control unit connected to a bus of a first network where first-type frames are transmitted following a first communication protocol and a second network where second-type frames are transmitted following a second communication protocol in an onboard network system. The electronic control unit sequentially receives the first-type and the second-type frames from the bus and the second network respectively, and stores in first and second reception buffers, respectively. The electronic control unit sequentially generates first-type data and second-type data by referencing the contents of the first reception buffer and the second reception buffer, and stores the first-type and second-type data in first and second transmission buffers, respectively. The first-type data is traveling control data for a vehicle, and the second-type data is other data. The first-type or second-type data that is priority type data is transmitted with priority.

    Abstract: A network hub is provided for an onboard network system. The onboard network system includes first and second networks for transmission of first-type and second-type frames following first and second communication protocols. The network hub includes a receiver that receives a first-type frame. A processor determines whether or not the first-type frame received by the receiver includes first information that is a base for a second-type frame to be transmitted to the second network, to obtain a determination result, and selects a port to send a frame based on the first-type frame based on the determination result. A transmitter sends the frame based on the first-type frame to a wired transmission path connected to the port selected by the processor based on the first-type frame received by the receiver.
