Secure Default Connection Pairing for IoT Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices in hostile or inaccessible environments, lacking user interfaces, face challenges in pairing with networks due to the need for user input of security information, which is cumbersome and difficult to update, especially when network or security information changes.
Innovation Solution
The method involves storing a connection list on devices with default and defined connection entries, establishing a secure default connection to receive new connection information, and then using this information to create a secure defined connection, allowing devices without user interfaces to pair securely and update connection details automatically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pairing methods requiring user input are used, then security information can be entered manually, but devices without user interfaces cannot be paired
Solution Approach 1:
The device automatically performs pairing operations without requiring user interaction. The processor autonomously generates connection information, establishes secure connections, and updates connection lists, enabling devices without user interfaces to pair independently
Solution Approach 2:
A secure default connection acts as an intermediary channel to transfer connection information between devices. This mediator enables indirect pairing where devices exchange necessary information through a trusted communication path without direct user intervention
2Adaptability or versatility
If manual updates of network information are implemented, then connection details can be changed, but updating all devices becomes cumbersome and difficult
Solution Approach 1:
Connection information is pre-stored in a connection list on each device, including default connection details. This preliminary preparation allows devices to immediately establish connections without requiring real-time manual configuration updates
Solution Approach 2:
The system automatically distributes updated connection information from one device to all other devices in the network. When connection details change, the updating device transmits new information through established secure connections, and receiving devices automatically update their own connection lists, eliminating manual intervention on each device
3Reliability
If secure connections are established without default connection information, then security is maintained, but devices cannot initially connect to exchange information
Solution Approach 1:
Default connection information is pre-configured on devices before deployment. This preliminary setup includes default SSIDs, passphrases, or other connection credentials that enable initial connection establishment without requiring prior secure communication channels
Solution Approach 2:
The connection process is segmented into two phases: first establishing a secure default connection using pre-stored information, then upgrading to a secure defined connection using exchanged connection information. This segmentation allows the system to overcome the bootstrap problem of establishing secure communication without prior secure channels

AI summary
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.
