Abstract

Techniques for verification of device pairing.

Claims

1. A method comprising:

pairing two electronic devices by exchanging identifiers between the two electronic devices;

combining the identifiers according to a pre-selected pattern;

generating a non-alphanumeric indication corresponding to the combined identifiers.

2. The method of claim 1 further comprising causing the two electronic devices to initiate and to play the respective non-alphanumeric indications in a synchronized manner.

3. The method of claim 1 wherein the non-alphanumeric indication comprises a visual indicator.

4. The method of claim 1 wherein the non-alphanumeric indication comprises an audio indicator.

5. The method of claim 1 wherein the exchanged identifiers comprise public security keys.

6. The method of claim 1 wherein the identifiers are exchanged using a wireless protocol.

7. The method of claim 1 wherein combining the indicators according to the pre-selected pattern comprises:

interleaving groups of one or more bits from the respective identifiers; and

performing a hash operation on the interleaved identifiers.

8. An article comprising a computer-readable medium having stored thereon instructions that, when executed, cause one or more processors to:

initiate a pairing procedure between two electronic devices including exchanging identifiers between the two electronic devices;

combine the identifiers according to a pre-selected pattern;

generate a non-alphanumeric indication corresponding to the combined identifiers.

9. The article of claim 8 further comprising instructions that, when executed, cause the one or more processors to cause the two electronic devices to initiate and to play the respective non-alphanumeric indications in a synchronized manner.

10. The article of claim 8 wherein the non-alphanumeric indication comprises a visual indicator.

11. The article of claim 8 wherein the non-alphanumeric indication comprises an audio indicator.

12. The article of claim 8 wherein the exchanged identifiers comprise public security keys.

13. The article of claim 8 wherein the identifiers are exchanged using a wireless protocol.

14. The article of claim 8 wherein the instructions that cause the one or more processors to combine the indicators according to the pre-selected pattern comprise instructions that, when executed, cause the one or more processors to:

interleave groups of one or more bits from the respective identifiers; and

perform a hash operation on the interleaved identifiers.

15. An apparatus comprising:

a device interface;

an output device to provide non-alphanumeric indications;

a processor coupled with the device interface and with the output device, the processor to cause a host electronic device to exchange identifiers with a remote electronic device via the device interface, to combine the exchanged identifiers according to a pre-selected pattern, to generate an indication of the combined identifiers and to cause the indication to be played by the output device.

16. The apparatus of claim 15 wherein the non-alphanumeric indication comprises a visual indicator.

17. The apparatus of claim 15 wherein the non-alphanumeric indication comprises an audio indicator and the output device comprises a speaker.

18. The apparatus of claim 15 wherein the exchanged identifiers comprise public security keys.

19. The apparatus of claim 15 wherein the identifiers are exchanged using a wireless protocol and the device interface comprises a wireless device interface.

20. A system comprising:

a wireless device interface having a substantially omni-directional antenna;

an output device to provide non-alphanumeric indications;

a processor coupled with the wireless device interface and with the output device, the processor to cause a host electronic device to exchange identifiers with a remote electronic device via the device interface, to combine the exchanged identifiers according to a pre-selected pattern, to generate an indication of the combined identifiers and to cause the indication to be played by the output device.

21. The system of claim 20 wherein the non-alphanumeric indication comprises a visual indicator.

22. The system of claim 20 wherein the non-alphanumeric indication comprises an audio indicator and the output device comprises a speaker.

23. The system of claim 20 wherein the exchanged identifiers comprise public security keys.

24. The system of claim 20 wherein the identifiers are exchanged using a wireless protocol and the device interface comprises a wireless device interface.
