Abstract

A key to configure a wireless device includes a non-volatile memory to store network configuration information including a unique network identifier. A circuit coupled to the non-volatile memory manages the network configuration information. An interface communicates data including the network configuration information with the wireless device.

Claims

1. A key comprising:

a non-volatile memory to store network configuration information for a wireless device on a network, the network configuration information including a unique network identifier;

a configuration managing circuit, coupled to the non-volatile memory, to manage the network configuration information; and

an interface to communicate data including the network configuration information with the wireless device.

2. The key of claim 1 wherein the configuration managing circuit includes a processor.

3. The key of claim 1 further comprising a key manager to manage the network configuration information;

and

wherein the non-volatile memory includes programmable memory.

4. The key of claim 3 wherein the non-volatile memory includes first partial keying material;

and

the key manager operating to receive second partial keying material from the wireless device, to generate complete keying material from the first partial keying material and said second partial keying material, and to store the complete keying material in the programmable memory.

5. The key of claim 4 wherein the second partial keying material is stored in the non-volatile memory.

6. The key of claim 3 further comprising a key receiver to receive a complete key from the wireless device and to store the complete key in the programmable memory.

7. A method comprising:

interfacing a key device to a wireless device;

sending network configuration information from the key device to the wireless device, the network configuration information including a unique identifier; and

de-interfacing the key device from the wireless device after said sending.

8. The method of claim 7 wherein sending the network configuration information includes sending complete keying material.

9. The method of claim 7 further comprising determining whether the key device includes complete keying material.

10. The method of claim 9 further comprising in response to determining whether the key device includes first partial keying material;

requesting second partial keying material from the wireless device;

receiving the second partial keying material; and

generating the complete keying material from the second partial keying material.

11. The method of claim 10 wherein generating the complete keying material includes combining the first partial keying material with the second partial keying material.

12. The method of claim 11 wherein sending the network configuration information includes sending the complete keying material.

13. The method of claim 9 further comprising in response to determining the key device does not include the complete keying material:

sending first keying material from the wireless device to the key device;

receiving the first keying material; and

storing the received first keying material in non-volatile memory.

14. The method of claim 13 wherein sending the network configuration information includes sending the first keying material.

15. A method comprising:

interfacing a key device to a wireless device;

determining whether the key device includes complete keying material;

in response to determining the key device does not include the complete keying material, generating the complete keying material;

sending network configuration information from the key device to the wireless device, the network configuration information including the complete keying material; and

de-interfacing the key device from the wireless device after said sending.

16. The method of claim 15 wherein generating the complete keying material includes:

receiving second partial keying material from the wireless device; and

generating the complete keying material from the second partial keying material.

17. The method of claim 16 wherein generating the complete keying material includes requesting the second partial keying material from the wireless device.

18. The method of claim 16 wherein generating the complete keying material includes combining the second partial keying material with first partial keying material stored in the non-volatile memory.

19. The method of claim 18 further including storing the complete keying material in non-volatile memory.

20. The method of claim 19 wherein said storing further includes overwriting the first partial keying material.

21. A wireless device, comprising:

a port to interface to a key of a specified type that includes network configuration information including complete keying material; and

a key manager to communicate with the key, the key manager to receive the network configuration information from the key.

22. The wireless device of claim 21 wherein the port is a serial port.

23. The wireless device of claim 21 wherein the key manager transfers partial keying material to the key to form the complete keying material in the key.

24. The wireless device of claim 21 further comprising nonvolatile storage to store the complete keying material.

25. The wireless device of claim 24 wherein the complete keying material is a cryptographic key.

26. The wireless device of claim 24 wherein the key manager uses the complete keying material to negotiate the cryptographic key.

27. The wireless device of claim 21 wherein the network configuration information further includes a unique network identifier.

28. A network comprising:

a key including;

a non-volatile memory to store network configuration information including a unique network identifier;

a circuit coupled to the non-volatile memory to manage the network configuration information; and

an interface to communicate data including the network configuration information with a wireless device; and

the wireless device configurable by the key to operate on the network, including;

a port to interface to the key; and

a key manager to communicate with the key, the key manager to receive the network configuration information from the key.

29. The network of claim 28 wherein the wireless device port is a serial port.

30. The network of claim 28 wherein the key manager transfers partial keying material to the key to form the complete keying material in the key.

31. An article comprising a machine readable medium including machine readable instructions that when executed by a machine, cause the machine to:

determine whether a key device, interfaced to a wireless device, includes complete keying material;

in response to determining the key device does not include the complete keying material, generate the complete keying material; and

send network configuration information from the key device to the wireless device, the network configuration information including the complete keying material.

32. The article of claim 31 wherein said generate the complete keying material includes:

receive second partial keying material from the wireless device; and

generate the complete keying material from the second partial keying material.

33. The article of claim 31 wherein said generate the complete keying material includes request the second partial keying material from the wireless device.
