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: The monitoring device includes a receiver and a processor. The receiver receives a frame from a communication network. The processor performs a first determination that determines whether the frame is illegal based on a result of message authentication for the frame and a second determination that determines whether the frame is illegal based on a state of the frame and a predetermined rule. In addition, the processor executes, in accordance with a combination of a result of the first determination and a result of the second determination, at least one of processing for the frame, processing for a transmission source device of the frame, change of contents to be notified to an external device, and change of priority of notification to the external device.

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.
