Abstract

Various techniques are provided to securely pair devices using default connection information. In one example, a method includes storing, on a first device, a connection list comprising a plurality of connection entries. The first device selects a default connection entry in the connection list. A secure default connection is established between the first device and a second device using the default connection entry. Defined connection information is received at the first device from the second device over the secure default connection. The defined connection information is stored in a defined connection entry of the connection list. A secure defined connection between the first device and the second device is established using the defined connection entry.

Claims

1. A method comprising:

storing, on a first device, a connection list comprising a plurality of connection entries;

selecting, by the first device, a default connection entry in the connection list;

establishing a secure default connection between the first device and a second device using the default connection entry;

receiving, at the first device over the secure default connection, defined connection information from the second device;

storing the defined connection information in a defined connection entry of the connection list; and

establishing a secure defined connection between the first device and the second device using the defined connection entry.

2. The method of claim 1, wherein the establishing a secure default connection comprises selectively configuring the first device as a station or an access point based on the selected default connection entry.

3. The method of claim 1, wherein the establishing a secure defined connection comprises attempting to establish a secure connection using each of the connection entries in the connection list until a secure default connection is established using the defined connection entry.

4. The method of claim 1, further comprising:

receiving, at the first device over the secure defined connection, additional defined connection information associated with a third device; and

storing the additional defined connection information in an additional defined connection entry of the connection list.

5. The method of claim 1, wherein the defined connection entry is a preexisting defined connection entry, wherein the storing the defined connection information comprises updating the preexisting defined connection entry.

6. The method of claim 1, wherein the selecting a default connection entry is performed in response to a powering on of the first device.

7. The method of claim 1, wherein the default connection information is associated with a serial number of the first device.

8. The method of claim 1, wherein each connection entry comprises a Service Set Identification (SSID), a passphrase, and an operating mode designation.

9. The method of claim 1, wherein the default connection entry is a recovery connection entry comprising a publicly available Service Set Identification (SSID) and a publicly available passphrase.

10. The method of claim 1, wherein the first device is a radar system configured to be installed on a watercraft, wherein the second device is a user device configured to display radar return information from the radar system received over the secure defined connection.

11. A system comprising:

a first device comprising;

a memory component configured to store a connection list comprising a plurality of connection entries;

a network interface; and

a processor configured to;

select a default connection entry in the connection list,

establish a secure default connection between the first device and a second device through the network interface using the default connection entry,

receive, over the secure default connection, defined connection information from the second device,

store the defined connection information in a defined connection entry of the connection list, and

establish a secure defined connection between the first device and the second device through the network interface using the defined connection entry.

12. The system of claim 11, wherein the processor is configured to selectively configure the first device as a station or an access point based on the selected default connection entry.

13. The system of claim 11, wherein the processor is configured to attempt to establish a secure connection using each of the connection entries in the connection list until a secure default connection is established using the defined connection entry.

14. The system of claim 11, wherein the processor is configured to:

receive, at the first device over the secure defined connection, additional defined connection information associated with a third device; and

store the additional defined connection information in an additional defined connection entry of the connection list.

15. The system of claim 14, further comprising the second device and the third device.

16. The system of claim 11, wherein the defined connection entry is a preexisting defined connection entry, wherein the processor is configured to update the preexisting defined connection entry with the defined connection information.

17. The system of claim 11, wherein the processor is configured to select the default connection entry in response to a powering on of the first device.

18. The system of claim 11, wherein the default connection information is associated with a serial number of the first device.

19. The system of claim 11, wherein the default connection entry is a recovery connection entry comprising a publicly available Service Set Identification (SSID) and a publicly available passphrase.

20. The system of claim 11, wherein the first device is a radar system configured to be installed on a watercraft, wherein the second device is a user device configured to display radar return information from the radar system received over the secure defined connection.
