Title: METHOD FOR DETECTING UNAUTHORIZED COMMUNICATION, SYSTEM FOR DETECTING UNAUTHORIZED COMMUNICATION, AND PROGRAM
Abstract:
In this method for detecting unauthorized communication in an on-vehicle network system, it is determined whether a message transmitted to a network is an attack message, and, if the message is an attack message, information related to the attack message is saved in a storage unit, and a communication pattern is identified from the information related to the attack message. Furthermore, it is determined whether the message conforms to a communication pattern, and the determination concerning whether the message is an attack message and the determination concerning whether the message conforms to the communication pattern are executed for each of a plurality of messages received from the network. In determinations concerning whether the messages are attack messages executed on messages received after execution of the determination concerning whether the messages conform to the communication pattern, the results from executed determinations concerning whether the messages are attack messages are used.
