    Abstract: A selection method is for selecting a reference message to be used to detect unauthorized communication in an in-vehicle network system including a network and one or more electronic control units connected to the network. The reference message is used as a reference for determining whether a message sent to the network is anomalous. The selection method includes: storing candidate information regarding one or more reference message candidates each being a candidate of the reference message; selecting, based on the candidate information regarding the one or more reference message candidates stored in the storing, the selection method for selecting the reference message from among the one or more reference message candidates; and selecting the reference message from among the one or more reference message candidates using the selection method.

    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.
