Secure pairing of networked devices
In one embodiment, a secure communication is initiated between two devices by generating a pairing message from a pre-determined static identification on the first device, transmitting the pairing message to the second device, generating a pairing identification from the static identification, and initiating a secure communication between the first and second device if the pairing message corresponds with the pairing identification.
1. A device comprising:
a communications interface configured to receive a message from a second device, the message comprising a first pairing identifier;
a button;
a display element; and
a processor configured to:
display, in sequence, a plurality of possible identifiers using the display element in response to the receiving of the message and prior to receiving a second message comprising any pairing identifier;
select one of the plurality of possible identifiers as a second pairing identifier based on activation of the button; and
establish a secure communication with the second device based on a determination of whether the first pairing identifier and the second pairing identifier match.
2. The device of claim 1 , wherein the first pairing identifier is a static identifier associated with the second device.
3. The device of claim 2 , wherein the static identifier is one or more digits or letters of a media access control (MAC) identifier of the second device.
4. The device of claim 2 , wherein the static identifier is located on an outer surface of the second device.
5. The device of claim 1 , wherein the message is a pairing message, a broadcast pairing request, or a pairing solicitation.
6. The device of claim 1 , wherein the device is a registrar device and the second device is an enrollee device.
7. The device of claim 1 , wherein the device is an enrollee device and the second device is a registrar device.
8. The device of claim 1 , wherein the second device is configured to display the first pairing identifier.
9. The device of claim 1 , wherein the second device generates the first pairing identifier.
10. A method comprising:
receiving, on a communications interface of a first device, a message from a second device, the message comprising a first pairing identifier;
displaying, in sequence on a display element of the first device, a plurality of possible identifiers in response to the receiving of the message and before receiving a second message comprising any pairing identifier;
selecting, by the first device, one of the plurality of possible identifiers as a second pairing identifier based on activation of a button on the first device;
establishing a secure communication with the second device based on a determination of whether the first pairing identifier and the second pairing identifier match.
11. The method of claim 10 , wherein the first pairing identifier is a static identifier associated with the second device.
12. The method of claim 11 , wherein the static identifier is one or more digits or letters of a media access control (MAC) identifier of the second device.
13. The method of claim 11 , wherein the static identifier is located on an outer surface of the second device.
14. The method of claim 10 , wherein the message is a pairing message, a broadcast pairing request, or a pairing solicitation.
15. The method of claim 10 , wherein the first device is a registrar device and the second device is an enrollee device or the first device is an enrollee device and the second device is a registrar device.
16. A system comprising:
means for receiving a message from a first device, the message comprising a first pairing identifier;
a means for displaying, in sequence, a plurality of possible identifiers using a display means in response to the receiving of the message and before receiving a second message comprising any pairing identifier;
a means for selecting one of the plurality of possible identifiers as a second pairing identifier based on activation of a user input means; and
means for establishing a secure communication with the first device based on a determination of whether the first pairing identifier and the second pairing identifier match.
17. The system of claim 16 , wherein the first pairing identifier is a static identifying means of the first device.
18. The system of claim 17 , wherein the static identifying means is one or more digits or letters of a media access control (MAC) identifying means of the first device.
19. The system of claim 17 , wherein the static identifying means is a pre-assigned indicia visible on an outer surface of the first device.
20. The system of claim 16 , wherein the message is a pairing message, a broadcast pairing request, or a pairing solicitation.
