The present invention provides an interactive method for address resolution protocol, the method comprises the following steps: step one, generating equipment of public key and private key, and all client devices under the public key equipment; step two, the device received ARP requests from the client message, using the signature algorithm to address the equipment the analytical protocol for sending packets and the generated private key signature, signature and ARP packets as ARP response messages to the client; and step three, the client received ARP reply message from the equipment after the state decided whether to refresh the response message in the client address resolution protocol according to the cache. Therefore, by adopting the method of the present invention, ARP spoofing can be fully prevented for devices supporting authentication of ARP when compatible with an existing device.
