Each area restricted network includes at least a master node. The method comprises a detection step of detecting that an access device has entered into an area restricted network in the area restricted network system; a receipt step of receiving, by a master node in the area restricted network, an authentication information request sent by the access device; a sending step of, in response to the authentication information request, generating and sending the authentication information for the access device by the master node in the area restricted network; and a request step of, by the access device, receiving the authentication information, and then utilizing the authentication information so as to send an authentication request to the central control device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Access control method, authentication method, and authentication device","description":"Disclosed is an access control method of an area restricted network system including a central control device and at least one area restricted network.
