An anomaly detection electronic control unit connected to an in-vehicle network includes: a communicator that receives a first communication message indicating speed information of a vehicle including the in-vehicle network and a second communication message indicating peripheral information of the vehicle; a processor; and a memory including at least one set of instructions that, when executed by the processor causes the processor to perform operations including: (A) determining a first traveling state of the vehicle based on the speed information and a second traveling state of the vehicle based on the peripheral information; (B) determining, by comparing the first traveling state with the second traveling state, that the first communication message is anomalous when the first traveling state is different from the second traveling state; and (C) executing processing to handle an anomaly when the first communication message is determined to be anomalous.
