Abstract
An unauthorized activity detection method is provided in an onboard network system having multiple electronic units (ECU) that perform communication via a bus, such that an occurrence of an unauthorized state can be detected by monitoring frames transmitted over the bus. The unauthorized activity detection method determines, by a monitoring electronic control unit using unauthorized activity detection rule information indicating a first condition, whether or not a set of frames received from the bus satisfies the first condition. The first condition being a condition regarding a relation in content between a first frame having a first identifier and a second frame having a second identifier that differs from the first identifier. And the method further detects the occurrence of the unauthorized state in a case where the first condition is not satisfied.
