a device which receives the request for the registration of the created access authority from the higher remote controller and registers the access authority of the lower remote controller created by the higher remote controller.

2. The system of claim 1, wherein the lower remote controller requests the higher remote controller to create the access authority through a location limited channel.

3. The system of claim 1, wherein the lower remote controller transmits the request for the creation of the access authority along with a hash of a public key of the lower remote controller.

4. The system of claim 3, wherein before creating the access authority to be granted to the lower remote controller, the higher remote controller requests the device for permission information.

5. The system of claim 4, wherein the higher remote controller transmits the request for the permission information along with the hash of the public key of the lower remote controller.

6. The system of claim 4, wherein the device offers the higher remote controller the permission information in a webpage form.

7. The system of claim 6, wherein the device offers the permission information along with a hash of a public key of the device.

8. The system of claim 1, wherein if the access authority of the lower remote controller transmitted from the higher remote controller is greater than an access authority of the higher remote controller, the device rejects to create the access authority.

9. The system of claim 1, wherein the device and the remote controller communicate with each other within a range of the access authority which is created, using a public key-based algorithm.

10. A system for creating an access authority, the system comprising:

a remote controller which grants higher and lower access authorities to a plurality of users through a user authentication, and if a user having the higher access authority creates an access authority to be granted to a user having the lower access authority, the remote controller grants a registration of the created access authority; and

a device which receives a request for the registration of the access authority which is created, from the remote controller and registers the access authority of the user having the lower access authority, the access authority being created by the user having the higher access authority.

11. The system of claim 10, wherein before creating the access authority to be granted to the user having the lower access authority, the remote controller requests the device for permission information.

12. The system of claim 11, wherein the remote controller transmits the request for the permission information along with a hash of a public key of the user having the lower access authority.

13. The system of claim 11, wherein the device offers the remote controller the permission information in a webpage form.

14. The system of claim 13, wherein the device offers the permission information along with a hash of a public key.

15. The system of claim 10, wherein if the access authority of the user having the lower access authority is higher than an access authority of the user having the higher access authority, the device does not create the access authority.

16. The system of claim 10, wherein the device and the remote controller communicate with each other within a range of the created access authority using a public key-based algorithm.

17. A method of creating an access authority in a system comprising a higher remote controller, at least one lower remote controller, and a device operated by the higher remote controller and the at least one lower remote controller, the method comprising:

requesting the higher remote controller to create an access authority via the at least one lower remote controller;

creating an access authority to be granted to the lower remote controller via the higher remote controller and requesting the device to register the created access authority; and

registering the access authority of the lower remote controller created by the higher remote controller via the device.

18. The method of claim 17, wherein the lower remote controller requests the higher remote controller to create the access authority through a location limited channel.

19. The method of claim 17, wherein the lower remote controller transmits the request for the creation of the access authority along with a hash of a public key of the lower remote controller.

20. The method of claim 19, before creating the access authority to be granted to the lower remote controller, further comprising:

requesting the device for permission information via the higher remote controller.

21. The method of claim 20, wherein the higher remote controller transmits the request for the permission information along with the hash of the public key of the lower remote controller.

22. The method of claim 20, further comprising:

offering the higher remote controller the permission information in a webpage form via the device.

23. The method of claim 22, wherein the device offers the permission information along with a hash of a public key of the device.

24. The method of claim 17, wherein if the access authority of the lower remote controller transmitted from the higher remote controller is higher than an access authority of the higher remote controller, the device does not create the access authority.

25. The method of claim 17, further comprising:

performing communications between the device and the lower remote controller within a range of the created access authority using a public key-based algorithm.

28. The method of claim 24, wherein the remote controller transmits the request for the permission information along with a hash of a public key of the user having the lower access authority.

26. A method of creating an access authority in a system comprising a remote controller and a device operated by the remote controller, the method comprising:

granting, by the remote controller, higher and lower access authorities to a plurality of users through a user authentication;

creating, by the remote controller, an access authority to be granted to the user having the lower access authority via the user having the higher access authority and requesting the device to register the access authority which is created; and

registering, by the device, the access authority of the user having the lower access authority, the access authority being created by the user having the higher access authority.

27. The method of claim 26, before creating the access authority, further comprising:

requesting the device for permission information via the remote controller.

29. The method of claim 27, further comprising:

offering the remote controller the permission information in a webpage form via the device.

30. The method of claim 29, wherein the device offers the permission information along with a hash of a public key.
