Abstract
A vehicle network is provided with a monitoring-purpose onboard control apparatus that detects illicit data through monitoring the data communication format predetermined in order to operate a communication protocol that is used in the vehicle network. Upon detecting illicit data whose communication format is different from the prescribed communication format, the monitoring-purpose onboard control apparatus performs a process of transmitting alarm information to onboard control apparatuses, and also performs a process of prohibiting gateways from routing the illicit data.

15. A vehicle network monitoring method that monitors communication data transmitted and received in a vehicle network where data is communicated between a plurality of onboard control apparatuses, the method comprising.
a detection process of detecting illicit data through monitoring a communication format of data predetermined in order to operate a communication protocol used in the vehicle network; - and
an inhibition process of inhibiting, when the illicit data is detected, illicit actions of the plurality of onboard control apparatuses resulting from entry of the illicit data into the vehicle network, wherein in the inhibition process, at least one of an alarm process of transmitting alarm information to the plurality of onboard control apparatuses and a prohibition process of transmitting, to a gateway provided in the vehicle network so as to relay the data, prohibition information that prohibits the gateway from routing the illicit data is executed. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
