Abstract: An anomaly detection device is a device for detecting an anomaly in a mobile body and includes: a type determiner that determines a type of an anomaly detected; a type change determiner that determines whether or not a change has occurred between a type of an anomaly detected last time and a type of an anomaly detected this time; and an anomaly detection log transmitter that transmits an anomaly detection log related to the anomaly detected this time when the change has occurred, and does not transmit the anomaly detection log related to the anomaly detected this time when the change has not occurred.

Abstract: An electronic control unit includes: a first determination unit which determines whether a message received is an address claim message; a second determination unit which determines, when it is determined that the message received is an address claim message, whether a device name included in the address claim message received is a predetermined device name; and a third determination unit which performs a predefined determination process, when it is determined that the device name included in the address claim message received is the predetermined device name, and determine whether the address claim message received is an unauthorized message according to a result of the predefined determination process.

Abstract: An information processing device includes a malicious message detector and an outputter. The malicious message detector detects a malicious message in a network based on an SA included in a claim message received from the network, a period that is based on a time at which the claim message is received, and a message received from the network before or after the claim message. The outputter outputs a detection result of the malicious message detector.

Abstract: An electronic control device includes: an acquisition unit that acquires state information indicating at least one of a state of a movable body and a state of an external environment in which the movable body is moving, and a control instruction indicating at least one of a steering control instruction for steering the movable body and an acceleration control instruction for adjusting acceleration of the movable body; and a determining unit that determines whether the control instruction is a false control instruction based on the at least one state indicated by the state information acquired and control indicated by the control instruction acquired.
