    Abstract: A first device, upon detecting participation in an authentication system, transmits new and old identification information of a first certificate revocation list that the first device manages to a second device. In a case where the new and old identification information of a second certificate revocation list that the second device manages is older than the new and old identification information of the received first certificate revocation list, the second device transmits a transmission request for the first certificate revocation list to the first device. Upon receiving the transmission request for the first certificate revocation list from the second device, the first device transmits the first certificate revocation list to the second device. the second device updates the second certificate revocation list using the received first certificate revocation list.

    Abstract: An authentication system according to the present disclosure includes a first controller connected to a first server via a first network, a second controller connected to a second server via a second network, and a device. The device compares a next issue date described in a first certificate revocation list acquired from the first controller and an issue date described in a second certificate revocation list acquired from the second controller thereby determining whether the first controller is invalid or not.

    Abstract: A communication unit receives a message in a network. A first anomaly detector detects an anomalous message by detecting values of a plurality of monitoring items from the message received by the communication unit and determining whether each of the detected values of the plurality of monitoring items is inside a corresponding first reference range and a corresponding second reference range. The second reference range is narrower than the first reference range. The first anomaly detector detects the message as the anomalous message, when any of the detected values is outside the first reference range, and detects the message as the anomalous message, when any of the detected values is inside the first reference range and is outside the second reference range and when a predetermined rule is satisfied.
