Abstract

In a secure cloud for transmitting packets of digital data, the packets may be repeatedly scrambled (i.e., their data segments reordered) and then unscrambled, split and then mixed, and/or encrypted and then decrypted as they pass through media nodes in the cloud. The methods used to scramble, split, mix and encrypt the packets may be varied in accordance with a state such as time, thereby making the task of a hacker virtually impossible inasmuch as he or she may be viewing only a fragment of a packet and the methods used to disguise the data are constantly changing.

Claims

1. A method of transmitting a packet containing digital data through a cloud, the cloud comprising a plurality of media nodes hosted on servers, the packet comprising a plurality of data segments, the method comprising scrambling the packet by changing the order of the data segments in the packet as the packet passes through one of the media nodes.

2. The method of claim 1 wherein said scrambling occurs in a gateway media node at which the packet enters the cloud, the method further comprising unscrambling the packet so as to recreate the order of data segments in the packet before said scrambling.

3. The method of claim 2 wherein said unscrambling is performed at a second gateway media node at which the packet exits the cloud.

4. The method of claim 1 further comprising re-scrambling the packet in a first media node within the cloud, said re-scrambling comprising unscrambling and then scrambling the packet.

5. The method of claim 4 further comprising:

transmitting said packet from said first media node within the cloud to a second media node within the cloud; and

re-scrambling said packet in said second media node by unscrambling and then scrambling the packet.

6. The method of claim 5 wherein a method used in scrambling said packet in said second media node is different from a method used in scrambling said packet in said first media node.

7. The method of claim 6 further comprising transmitting a state relating to said packet from said first media node to said second media node.

8. The method of claim 7 wherein said state is based on a time at which said packet was scrambled in said first media node.

9. The method of claim 7 further comprising providing said second media node with a selector, said selector containing a list of scrambling methods, each of said scrambling methods being associated with a state.

10. The method of claim 9 wherein said second media node uses said state to select a particular scrambling method from said list of scrambling methods in said selector.

11. The method of claim 10 wherein said second media node uses the particular scrambling method selected from said list of scrambling methods to scramble said packet.

16. The method of claim 7 wherein said state is based on a time at which said packet was encrypted in said first media node.

17. The method of claim 7 further comprising providing said second media node with a selector, said selector containing a list of encryption methods, each of said encryption methods being associated with a state.

18. The method of claim 9 wherein said second media node uses said state to select a particular encryption method from said list of encryption methods in said selector.

19. The method of claim 10 wherein said second media node uses the particular encryption method selected from said list of encryption methods to scramble said packet.

20. A method of transmitting digital data through a cloud, the cloud comprising a plurality of media nodes hosted on respective servers, the method comprising:

splitting a first packet into a plurality of smaller packets at a first media node in said cloud; and

mixing a second packet with a third packet at a second media node in said cloud.

21. A method of transmitting packets containing digital data through a cloud, the cloud comprising a plurality of media nodes hosted on respective servers, the method comprising re-encrypting said packet at a first media node with the cloud, said re-encrypting comprising decrypting and then encrypting said packet.

22. The method of claim 21 further comprising

transmitting said packet from said first media node within the cloud to a second media node within the cloud;

and

re-encrypting said packet in said second media node by decrypting and then encrypting said packet.

23. The method of claim 22 wherein said encrypting said packet at said first media node is performed using an encryption method different from an encryption method used in encrypting said packet at said second media node.

24. The method of claim 23 further comprising transmitting a state relating to said packet from said first media node to said second media node.
