Abstract
An anomaly detection system is on an in-vehicle network including: a first network connected to first devices that communicate using a first protocol; and a second network connected to second devices that includes a driving assistance controller communicates using a second protocol. The system includes: a communicator receiving, through the first network, first unit data including (i) source information indicating a source first device and (ii) second unit data including a data identifier; a database storing rule; and an anomaly determiner that determines whether the first unit data has anomaly by comparing the source information and the data identifier with the rule. Based on the rule, the first unit data is determined to have anomaly when the source first device is a sensing device and, according to the identifier, the second unit data is to be received by the controller.
