Inter-apparatus authentication system andinter-apparatus authentication method, communication device, and computer program
First Claim
1. A device-to-device authentication system for authenticating whether or not devices on a network are connected within a certain range, characterized in that:
- each of said devices interconnected via said network has a mediating device interface for physically accessing a mediating device such that said mediating device is removable, and local environment management means for authenticating that another device physically accessing said same mediating device within a predetermined period of time is located in a local environment where contents are available;
wherein use of said contents is allowed between said devices in said local environment.

Abstract
In view of the fact that devices connected on a home network are located in home, that is, at close range and therefore a user can physically access the devices within a relatively short period of time, identifying whether or not a home server for distributing the contents and a client terminal using the contents are connected to the same home network based on whether or not they can share access to the same physical medium within a short period of time. The authenticity of devices connected on a home network connected to an external network via a router is authenticated.
