摘要

Authentication communication device (310) is a communication device constituting a network constructed by a plurality of communication devices are connected to each other. Transmitting and receiving unit (311) and (320), receives the identification information of the communication device holding authentication information for authenticating (320) the authenticated communication device the authenticated communication device that is not connected to the own device . Acquisition unit (312) acquires the authentication information from the communication device corresponding to the identification information received by the receiving unit (311). The authentication processing unit (316), by using the authentication information acquired by the acquisition unit (312), and performs authentication processing for the (320) the authenticated communication device. If the authentication process by (316) the authentication processing unit is established, the communication unit (317) communicates the authentication of the communication device (320).
