Abstract
The present invention provides a device and a method for accurately and efficiently controlling an access from an external network to an internal network. Both a client device connectable to the external network and an application gateway store shared secret information (Secret) including a client ID: GUID(C) as an ID generated by the client and a server ID: GUID(S) as an ID generated by the application gateway in respective storage units. In response to an access request from the client, the application gateway determines whether the client has appropriate shared secret information (Secret) so as to determine an access right. With this configuration, a right of access from the external network to the internal network, such as a home network, can be efficiently and accurately determined.
