Abstract
For the first use of an authentication device, a remote machine makes a query of an address of a local machine to be permanently assigned to the remote machine, to which the authentication device is connected, to a management server. In response to the query, the management server determines the local machine to be permanently assigned to the remote machine and notifies the remote machine of an address of the local machine. The remote machine remotely controls the local machine specified by the address notified from the management server.
