<p>To provide a technology enabling establishment of compatibility between providing convenience for a user inputting authentication information and ensuring high security of a network. An authentication network system of the present invention is comprised so that: a first authentication device (1) receives first authentication information via a first network (LAN1) from a communication device (6), judges whether the first authentication information is authenticated or non-authenticated and, if the first authentication information is authenticated, notifies of the second authentication information; a second authentication device (2) receives the second authentication information, judges whether the second authentication information is authenticated or non-authenticated by comparing the second authentication information with information registered beforehand and, if the second authentication information is authenticated, notifies a connection control device (3) ; and the connection control device (3) switches over the connection of the authenticated communication device to a second network (LAN2) from the first network (LAN1).</p> |
