Abstract

A gaming system may include a gaming security arbiter, and first and second network gaming devices, each including a processor and a memory operatively coupled to the processor. The arbiter controller may be programmed to receive a request from the first network gaming device for a communication session between the first network gaming device and the second network gaming device, to provide a first encryption key to the first network gaming device and to provide a second encryption key to a second network gaming device. The first controller may transmit the request to the gaming security arbiter, receive the first encryption key, encrypt a message using the first encryption key and transmit the encrypted message to the second network gaming device. The second controller may be programmed to receive the second encryption key, receive the encrypted message and decrypt the encrypted message using the second encryption key.

Claims

1. A gaming system comprising:

a first network gaming device, a second network gaming device and a gaming security arbiter;

the first network gaming device being operatively coupled to said gaming security arbiter, and comprising a first network gaming device controller configured to (i) transmit a request to said gaming security arbiter for a communication session with said second network gaming device, (ii) receive said first encryption key from said gaming security arbiter, (iii) create an encrypted message from a message content using said first encryption key, and (iv) transmit said encrypted message to said second network gaming device;

the second network gaming device being operatively coupled to said first network gaming device and said gaming security arbiter, and comprising a second network gaming device controller configured to (i) receive said second encryption key from said gaming security arbiter, (ii) receive said encrypted message from said first network gaming device, and (iii) decrypt said encrypted message using said second encryption key, and;

at least one of said first and second network gaming device controllers is configured to request, according to a security level relating to said message, a respective encryption, key, said first network gaming device controller being configured to encrypt said message according to said security level; and

the gaming security arbiter comprising an arbiter controller configured to (i) receive a request from the first network gaming device, said request comprising a request for a communication session between said first network gaming device and the second network gaming device, (ii) provide a first encryption key to said first network gaming device, and (iii) provide a second encryption key to said second network gaming device;

wherein;

said arbiter controller is further configured to;

communicate with the first network gaming device and a host;

determine encryption methods supported by the host and by the first network gaming device;

select an encryption method supported by both the first network gaming device and the host, and

select the first and second encryption keys based on both the supported methods and the security level related to said message.

2. A gaming system as defined in claim 1,

wherein said arbiter controller is programmed to encrypt said first and second encryption keys,

wherein said first network gaming device controller is programmed to decrypt said first encryption key,

wherein said second network gaming device controller is programmed to decrypt said second encryption key.

3. A gaming system as defined in claim 1,

wherein said arbiter controller is programmed to receive data from at least one of the first and second network gaming devices, said data relating to one or more of the following:

services data relating to one or more services provided by at least one of said first and second network gaming devices, resources data relating to one or more resources provided by at least one of said first and second network gaming devices, capabilities data relating to capabilities of at least one of said first and second network gaming devices,

wherein said arbiter controller is programmed to select said second network gaming device based on said data received from said second network gaming device.

4. A gaming system as defined in claim 1,

wherein said arbiter controller is programmed to determine parameters for said communication session,

wherein said first and second network gaming device controllers are programmed to cause said first and second network gaming devices to communicate in accordance with said communication parameters.

5. A gaming system as defined in claim 1, wherein:

said arbiter controller is programmed to provide said first network gaming device controller with data regarding one or more network gaming devices, and

said first network gaming device controller is programmed to select said second network gaming device from said one or more network gaming devices based on said data.

6. A gaming system as defined in claim 1, wherein:

said arbiter controller is programmed to provide said first network gaming device controller with a plurality of encryption keys, and

said first network gaming device controller is programmed to select said first encryption key from said plurality of encryption keys.

7. A gaming system as defined in claim 1, wherein:

said first network gaming device controller is programmed to include an encryption key identifier with said encrypted message, wherein said encryption key identifier identifies said first encryption key, and

said second network gaming device controller is programmed to select said second encryption key based on said encryption key identifier.

8. A gaming system as defined in claim 1, wherein:

said second network gaming device controller is programmed to request confirmation of the authenticity of said first network gaming device from said gaming security arbiter,

said arbiter controller is programmed to provide confirmation of the authenticity of said first network gaming device to the second network gaming device, and

said second network gaming device controller is programmed to receive and decrypt said encrypted message from said first network gaming device in response to said confirmation.

9. A gaming system as defined in claim 1, wherein said at least one of said first and second network gaming devices comprises one of the following:

a gaming unit or a network computer.
