Abstract

An authentication system includes a first authentication key associated with a first device, the first authentication key having a corresponding authentication level, a second authentication key associated with a second device, the second authentication key having a corresponding authentication level, and an enhanced authentication key generated when the first and second authentication keys are combined, the enhanced authentication key having an authentication level that represents a higher authentication level than the authentication level of the first authentication key and the authentication level of the second authentication key.

Claims

1. An authentication system, comprising:

a first authentication key associated with a first device, the first authentication key having a corresponding authentication level;

a second authentication key associated with a second device, the second authentication key having a corresponding authentication level; and

an enhanced authentication key generated when the first and second authentication keys are combined, the enhanced authentication key having an authentication level that represents a higher authentication level than the authentication level of the first authentication key and the authentication level of the second authentication key.

2. The system of claim 1, wherein each of the first and second authentication keys corresponds to an authentication level having respective first privileges.

3. The system of claim 2, wherein the enhanced authentication key corresponds to an authentication level having second privileges.

4. The system of claim 3, wherein the enhanced authentication key is generated when with the first device is proximate to the second device by wireless communication directly between the first device and second device.

5. The system of claim 3, wherein the enhanced authentication key is generated when the first device and the second device are proximate to a geographical region.

6. The system of claim 3, wherein the enhanced authentication key is generated based on time of day.

7. The system of claim 3, wherein the enhanced authentication key is a static key.

8. The system of claim 3, wherein the enhanced authentication key is a dynamic key.

9. A method, comprising:

generating a plurality of authentication keys, each authentication key having a corresponding authentication level; and

combining at least two of the authentication keys to generate an enhanced authentication key, the enhanced authentication key having an authentication level that represents a higher authentication level than the authentication level of any of the plurality of authentication keys.

10. The method of claim 9, wherein each of the plurality of authentication keys corresponds to an authentication level having first privileges.

11. The method of claim 10, wherein the enhanced authentication key corresponds to an authentication level having second privileges.

12. The method of claim 11, further comprising generating the enhanced authentication key when a first device having a first authentication key is proximate to a second device having a second authentication key by wireless communication directly between the first device and second device.

13. The method of claim 11, further comprising generating the enhanced authentication key when a first device having a first authentication key and a second device having a second authentication key are proximate to a geographical region.

14. The method of claim 11, further comprising generating the enhanced authentication key based on time of day.

15. The method of claim 11, wherein the enhanced authentication key is a static key.

16. The method of claim 11, wherein the enhanced authentication key is a dynamic key.

17. A system, comprising:

means for generating a plurality of authentication keys, each authentication key having a corresponding authentication level; and

means for combining at least two of the authentication keys to generate an enhanced authentication key, the enhanced authentication key having an authentication level that represents a higher authentication level than the authentication level of any of the plurality of authentication keys.

18. The system of claim 17, further comprising means for generating the enhanced authentication key when a first device having a first authentication key is proximate to a second device having a second authentication key by wireless communication directly between the first device and second device.

19. The system of claim 17, further comprising means for generating the enhanced authentication key when a first device having a first authentication key and a second device having a second authentication key are proximate to a geographical region.

20. The system of claim 17, further comprising means for generating the enhanced authentication key based on time of day.
