Push button configuration of multimedia over coax alliance (MoCA) devices

1. A method, the method comprising:

in a first device coupled to a multimedia over coax alliance (MoCA) network via coaxial cabling utilized by said MoCA network:

receiving, from a second device, via said coaxial cabling utilized by said MoCA network, a first indication that a configuration button on said second device has been activated;

receiving, from a third device, via said coaxial cabling utilized by said MoCA network, a second indication that a configuration button on said third device has been activated;

determining a first time associated with said first indication that said configuration button on said second device has been activated;

determining a second time associated with said second indication that said configuration button on said third device has been activated; and

determining whether to allow said second device to be authenticated on said MoCA network based on a time interval between said first time associated with said first indication that said configuration button on said second device was activated and said second time associated with said second indication that said configuration button on said third device was activated.

2. The method according to claim 1 , comprising allowing said second device to be authenticated on said MoCA network when said configuration button of said second device and said configuration button of said third device are both activated within said time interval.

3. The method according to claim 2 , comprising, after determining to allow said second device to be authenticated, sending a message to said second device, wherein said message comprises information that enables said second device to determine a privacy password of said MoCA network.

4. The method according to claim 1 , comprising preventing said second device from being authenticated on said MoCA network when said configuration button of said second device and said configuration button of said third device are not both activated within said time interval.

5. The method according to claim 1 , wherein said indication from said third device comprises a layer 2 management entity (L2ME) message or a Protocol Information element.

6. The method according to claim 1 , comprising:

receiving, from said second device, a message requesting information that indicates whether said MoCA network supports push-button configuration; and

in response to said received message, transmitting a response to said second device, said response indicating whether push-button configuration is supported by said MoCA network.

7. The method according to claim 1 , wherein said indication from said second device comprises a discovery request.

8. The method according to claim 7 , comprising:

ignoring said discovery request when said configuration button of said second device and said configuration button of said third device are not both activated within said time interval; and

transmitting a response to said discovery request when said configuration button of said second device and said configuration button of said third device are both activated within said time interval.

9. The method according to claim 8 , wherein said response comprises information enabling said second device to determine a privacy password of said MoCA network.

10. The method according to claim 9 , comprising:

after transmitting said response, receiving an encrypted message from said second device;

decrypting said received encrypted message utilizing a key generated from said privacy password;

admitting said second device to said MoCA network if:

said message is received within a determined amount of time of said activation of said configuration button on said third device; and

said decrypting results in a valid start_admission request being recovered from said received message.

11. A system, the system comprising:

one or more circuits for use in a first device coupled to a multimedia over coax alliance (MoCA) network via coaxial cabling utilized by said MoCA network, said one or more circuits being operable to:

receive, from a second device, via said coaxial cabling utilized by said MoCA network, an indication that a configuration button on said second device has been activated;

receive, from a third device, via said coaxial cabling utilized by said MoCA network, an indication that a configuration button on said third device has been activated; and

determine a first time associated with said first indication that said configuration button on said second device has been activated;

determine a second time associated with said second indication that said configuration button on said third device has been activated; and

determine whether to allow said second device to be authenticated on said MoCA network based on a time interval between said first time associated with said first indication that said configuration button on said second device was activated and said second time associated with said second indication that said configuration button on said third device was activated.

12. The system according to claim 11 , wherein said one or more circuits are operable to allow said second device to be authenticated on said MoCA network when said configuration button of said second device and said configuration button of said third device are both activated within said time interval.

13. The system according to claim 12 , wherein said one or more circuits are operable to, after determining to allow said second device to be authenticated, sending a message to said second device, wherein said message comprises information that enables said second device to determine a privacy password of said MoCA network.

14. The system according to claim 11 , wherein said one or more circuits are operable to prevent said second device from being authenticated on said MoCA network when said configuration button of said second device and said configuration button of said third device are not both activated within said time interval.

15. The system according to claim 11 , wherein said indication from said third device comprises a layer 2 management entity (L2ME) message or a Protocol Information Element.

16. The system according to claim 11 , wherein said one or more circuits are operable to:

receive, from said second device, a message requesting information that indicates whether said MoCA network supports push-button configuration; and

in response to said received message, transmit a response to said second device, said response indicating whether push-button configuration is supported by said MoCA network.

17. The system according to claim 11 , wherein said indication from said second device comprises a discovery request.

18. The system according to claim 17 , wherein said one or more circuits are operable to:

ignore said discovery request when said configuration button of said second device and said configuration button of said third device are not both activated within said time interval; and

transmit a response to said discovery request when said configuration button of said second device and said configuration button of said third device are both activated within said time interval.

19. The system according to claim 18 , wherein said response comprises information enabling said second device to determine a privacy password of said MoCA network.

20. The system according to claim 19 , wherein said one or more circuits are operable to:

after transmitting said response, receiving an encrypted message from said second device;

decrypting said received encrypted message utilizing a key generated from said privacy password;

admitting said second device to said MoCA network if:

said message is received within a determined amount of time of said activation of said configuration button on said third device; and

said decrypting results in a valid start_admission request being recovered from said received message.
