Abstract

A method of configuring an ad-hoc wireless network between an authenticator and a plurality of wireless devices seeking authentication includes assigning a wireless device as the authenticator and receiving a first setup message transmitted from a first device seeking authentication to the authenticator and initiating a first handshake process between the authenticator and the first device seeking authentication. The method also includes receiving a second setup message transmitted from a second device seeking authentication to the authenticator. The second setup message is received by the authenticator prior to completion of the first handshake process. The method further includes initiating a second handshake process between the authenticator and the second device seeking authentication. The second handshake process is initiated prior to completion of the first handshake process. Moreover, the method includes completing the first handshake process and completing the second handshake process.

Claims

1. A method used to configure an ad-hoc wireless network between an authenticator and a plurality of wireless devices seeking authentication, the method comprising:

initiating a first handshake process between the authenticator and the first device seeking authentication, the first handshake process being initiated in response to a triggering event;

receiving a setup message transmitted from a second device seeking authentication to the authenticator, wherein the setup message is received by the authenticator prior to completion of the first handshake process; and

initiating a second handshake process between the authenticator and the second device seeking authentication, wherein the second handshake process is initiated prior to completion of the first handshake process.

2. The method of claim 1 wherein the authenticator comprises a registrar and the plurality of wireless devices seeking authentication comprise a plurality of enrollees;

and

further comprising;

completing the first handshake process; and

completing the second handshake process.

3. The method of claim 1 wherein the first handshake process and the second handshake process are performed concurrently.

4. The method of claim 3 further comprising determining whether the second device is an authorized enrollee.

5. The method of claim 4 wherein determining whether the second device is an authorized enrollee is based on a number of current enrollees.

6. The method of claim 1 wherein the authenticator, the first device seeking authentication, and the second device seeking authentication comprise wireless gaming devices.

7. The method of claim 1 wherein the wireless device is assigned as the authenticator based on input from a user of the wireless device, the authenticator comprising a registrar.

8. The method of claim 1 wherein the authenticator maintains a first state machine associated with the first device seeking authentication and a second state machine associated with the second device seeking authentication.

9. The method of claim 8 wherein the authenticator maintains a database adapted to store information related to the first handshake process and the second handshake process.

10. The method of claim 1 wherein the setup message comprises a second setup message;

further comprising receiving a first setup message transmitted from the first device seeking authentication; and

wherein the first setup message is transmitted in response to a user action taken on the first device seeking authentication.

11. The method of claim 1, wherein the triggering event comprises a single user action taken on the authenticator, and wherein initiating the first handshake process and initiating the second handshake process are performed in response to the single user action taken on the authenticator.

12. A wireless device used to configure an ad-hoc wireless network between the wireless device and a plurality of wireless devices seeking authentication, the wireless device comprising:

an interface configured to receive a setup message; and

at least one processor in communication with the interface and configured to;

initiate a first handshake process with a first device seeking authentication, the first handshake process being initiated in response to a triggering event;

in response to receiving the setup message transmitted from a second device seeking authentication, initiate a second handshake process with the second device seeking authentication,

wherein the setup message is received prior to completion of the first handshake process, and

wherein the second handshake process is initiated prior to completion of the first handshake process.

13. The wireless device of claim 12 wherein the wireless device comprises a registrar and the plurality of wireless devices seeking authentication comprise a plurality of enrollees.

14. The wireless device of claim 12 wherein the at least one processor is configured to perform the first handshake process and the second handshake process concurrently.

15. The wireless device of claim 14 wherein the at least one processor is further configured to determine whether the second device is an authorized enrollee.

16. The wireless device of claim 15 wherein the at least one processor is configured to determine whether the second device is an authorized enrollee based on a number of current enrollees.

17. The wireless device of claim 12 wherein the wireless device, the first device seeking authentication, and the second device seeking authentication comprise wireless gaming devices.

18. The wireless device of claim 12 wherein the wireless device is assigned as an authenticator based on input from a user of the wireless device, the authenticator comprising a registrar.

19. The wireless device of claim 18 wherein the triggering event comprises a single user action taken on the authenticator, and wherein the at least one processor is configured to initiate the first handshake process and initiate the second handshake process in response to a single user action taken on the authenticator.

20. The wireless device of claim 12 wherein the at least one processor is configured to perform the first handshake process according to a first state machine and to perform the second handshake process according to a second state machine.

21. The wireless device of claim 20 further comprising a database configured to store information related to the first handshake process and the second handshake process.
