Abstract

Claims (41)

1. A method comprising:

receiving in a first gaming device from a second gaming device, encrypted gaming data over a first data channel between the first gaming device and the second device, the first data channel established using a first protocol over a first transmission medium;

receiving in the first gaming device from the second gaming device, an encryption key over a second data channel, the second data channel established using a second protocol over a second transmission medium, the second protocol being different than the first protocol and the second transmission medium being separate from the first transmission medium;

decrypting, at the first gaming device, the received encrypted gaming data with the received encryption key; and

storing the decrypted game data in a storage device of the first gaming device.

2. The method of claim 1 , wherein the first gaming device is a gaming machine and the second gaming device is a gaming host.

3. The method of claim 1 , wherein the second data channel is established using a radio frequency protocol, an infrared protocol, a power line protocol, or ethernet protocol.

4. A method comprising:

performing the following operations in a first gaming device,

selecting gaming data for transmission;

encrypting the gaming data using an encryption key;

transmitting the encrypted gaming data to a second gaming device over a first data channel of a first transmission medium between the first gaming device and a second device, the first data channel established using a first protocol; and

transmitting the encryption key to the second gaming device over a second data channel of a second transmission medium between the first gaming device and the second device, the second data channel established using a second protocol and the second protocol being different than the first protocol and the second transmission medium being separate from the first transmission medium.

5. The method of claim 4 , wherein the first transmission medium is a wired transmission medium.

6. The method of claim 5 , wherein the second transmission medium is a wireless transmission medium.

7. A method comprising:

receiving in a gaming device from a gaming host, a first portion of an interleaved data stream over a first data channel established over a first transmission medium of a plurality of separate transmission mediums, the first portion of the interleaved data stream including a portion of encrypted gaming data and a portion of an encryption key;

receiving in the gaining device from the gaming host, a second portion of the interleaved data stream over a second data channel established over a second transmission medium of the plurality of separate transmission mediums, the second portion of the interleaved data stream including another portion of the encrypted gaming data and another portion of the encryption key;

reassembling, at the gaming device, the encrypted gaming data and encryption key using the first and second portions of the interleaved data stream; and

decrypting, at the gaming device, the encrypted gaming data using the encryption key.

8. The method of claim 7 , wherein the gaming device is a gaming machine.

9. A system comprising:

a first gaming device comprising:

at least one processor;

a storage device comprising instructions, which when executed by the at least one processor, configure the processor to:

encrypt a gaining data stream into an encrypted data stream using an encryption key;

transmit the encrypted gaming data stream to a second gaming device over a first data channel of a plurality of data channels, the first data channel established over a first transmission medium; and

transmit the encryption key to the second gaming device over a second data channel of the plurality of data channels, the second data channel established over a second transmission medium separate from the first transmission medium; and

wherein the first data channel is established using a first protocol selected from the group comprising Ethernet, Asynchronous Transfer Mode, Digital Subscriber Line, and 802.11, and the second data channel is established using a second protocol selected from the group comprising Ethernet, Asynchronous Transfer Mode, Digital Subscriber Line, and 802.11, wherein the first protocol is different than the second protocol.

10. The system of claim 9 , wherein the first gaming device is a gaming host and the second gaming device is a gaming machine.

11. The method of claim 4 , further comprising randomly selecting the first data channel and the second data channel from a set of available data channels.

12. The method of claim 11 , wherein the number of data channels in the set of available data channels is greater than two.

13. A non-transitory computer-readable medium comprising instructions, which when executed by at least one processor, configure the at least one processor to:

receive in a first gaming device from a second gaming device, encrypted gaming data over a first data channel between the first gaming device and the second device, the first data channel established using a first protocol over a first transmission medium;

receive in the first gaming device from the second gaming device, an encryption key over a second data channel, the second data channel established using a second protocol over a second transmission medium, the second protocol being different than the first protocol and the second transmission medium being separate from the first transmission medium;

decrypt, at the first gaming device, the received encrypted gaming data with the received encryption key; and

store the decrypted game data in a storage device of the first gaming device.

14. The non-transitory computer-readable medium of claim 13 , wherein the first gaming device is a gaming host and the second gaming device is a client gaming machine.

15. The non-transitory computer-readable medium of claim 13 , wherein the first transmission medium is a wireless transmission medium.

16. The non-transitory computer-readable medium of claim 15 , wherein the second transmission medium is a wired transmission medium.

17. The non-transitory computer-readable medium of claim 13 , wherein the first and second data channels are randomly selected from a set of available data channels, wherein the number of available data channels is greater than two.
