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.
