Abstract

Systems and methods that prevent unauthorized access in a communications network are provided. In one embodiment, a system that prevents unauthorized access to a network device may include, for example, a network device and a headend. The headend may be coupled to a communications network. The network device may be deployed in a home environment and may be communicatively coupled to the communications network via the headend. The headend may be adapted, for example, to determine whether a request to access the network device is authorized.

Claims

1. In a system that prevents unauthorized access to a network device, the system comprising a network device, a cable television headend and a communications network, the cable television headed being coupled to the communications network, the cable television headend being adapted to determine whether a request to access the network device is authorized, the network device comprising:

at least one of a computer, a storage device, set-top box circuitry, a television, a display and/or a remote control,

wherein the network device is deployed in a home environment and communicatively coupled to the communications network via the cable television headend; and

wherein the cable television headend is adapted to determine whether a particular service provider, which is seeking access to the network device, is authorized to send data to the network device.

2. The network device according to claim 1, wherein the cable television headend is adapted to perform at least one of the following:

Internet protocol registration, identification registration and/or digital rights management.

3. The network device according to claim 2, wherein the cable television headend is adapted to perform at least one of the following:

channel/program set up, channel/program management, anonymous proxy services, media caching, media storage, billing and/or tracking.

4. The network device according to claim 3, wherein the cable television headend is adapted to process at least one of the following:

a device identification, an IP address, a digital certificate and/or a key.

5. The network device according to claim 4, wherein the cable television headend is adapted to store at least one of the following:

a device identification, a public key, a hashing signature and/or an IP address.

6. The network device according to claim 1, wherein the cable television headend is adapted to prevent unauthorized data from reaching the network device.

7. The network device according to claim 6, wherein the data is received by the cable television headend from the communications network.

8. The network device according to claim 1, wherein the cable television headend is adapted to employ at least one of the following:

authentication techniques, encryption techniques and/or decryption techniques.

9. The network device according to claim 1, wherein the cable television headend is adapted to facilitate pushing a file residing in an authorized device to the network device and/or to a storage device coupled to the network device.

10. The network device according to claim 9, wherein the pushed file is transported through the cable television headend to the network device and/or to the storage device coupled to the network device.

11. The network device according to claim 1, the system comprising a service provider coupled to the communications network and attempting to access the network device via the cable television headend, wherein the service provider provides at least one of a password and/or a code to the cable television headend so that the cable television headend can determine whether the service provider is authorized to access the network device.

12. The network device according to claim 1, wherein the communications network comprises an Internet-protocol-based communications network.

13. The network device according to claim 1, wherein the cable television headend comprises at least one of the following:

a cable headend, a satellite headend and/or a digital subscriber line headend.

14. The network device according to claim 1, wherein the cable television headend is adapted to provide at least some of the functionality of a media exchange server.

15. The network device according to claim 1, wherein the cable television headend is adapted to perform at least one of the following:

channel/program set up, channel/program management, anonymous proxy services, media caching, media storage, billing and/or tracking.

16. The network device according to claim 1, wherein the cable television headend is adapted to process at least one of the following:

a device identification, an Internet protocol address, a digital certificate and/or a key.

17. The network device according to claim 1, wherein the cable television headend is adapted to store at least one of the following:

a device identification, a public key, a hashing signature and/or an Internet protocol address.

18. The network device according to claim 1, wherein the cable television headend is deployed outside of the home environment of the network device.

19. The network device according to claim 18, wherein the communications network is external to the cable television headend, the network device and any other network communicatively disposed between the cable television headend and the network device.

20. The network device according to claim 19, wherein the cable television headend comprises a satellite cable television headend.

21. The network device according to claim 19, wherein the cable television headend comprises a digital subscriber line cable television headend.

22. The network device according to claim 19, wherein the cable television headend comprises a cable television headend.

23. The network device according to claim 19, wherein the cable television headend is adapted to perform channel or program set up.

24. The network device according to claim 19, wherein the cable television headend is adapted to perform anonymous proxy services.

25. The network device according to claim 19, wherein the cable television headend is adapted to perform billing.

26. The network device according to claim 19, wherein the cable television headend is adapted to perform media storage.

27. The network device according to claim 19, wherein the network device comprises a set top box and the cable television headend comprises a satellite cable television headend.

28. The network device according to claim 19, wherein the network device comprises a set top box and the cable television headend comprises a digital subscriber line cable television headend.

29. The network device according to claim 19, wherein the network device comprises a set top box and the cable television headend comprises a cable television headend.

30. The network device according to claim 19, wherein the cable television headend is adapted to perform Internet protocol registration.

31. The network device according to claim 19, wherein the cable television headend is adapted to perform identification registration.

32. The network device according to claim 19, wherein the cable television headend is adapted to perform digital rights management.
