Virtual Pairing Using Existing Wireless Connection Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless peer-to-peer connections require repeated user involvement for pairing, which is inconvenient and inefficient, especially when transitioning between different connection types or in environments with interference.
Innovation Solution
A method for virtual pairing of peer devices using a nonce generated at one device, forwarded over an existing wireless connection, to establish a new high-speed wireless connection using a key derivation function based on the shared key of the existing connection, eliminating the need for user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional wireless pairing methods are used, then secure connections are established, but user involvement is required for each pairing operation
Solution Approach 1:
The system performs preliminary pairing actions through alternative methods (NFC, QR code, or existing Bluetooth connection) to establish trust between devices before automated Wi-Fi connection can occur. This preliminary authentication enables subsequent automatic connections without repeated user involvement.
Solution Approach 2:
The patent introduces intermediary pairing mechanisms (NFC handshake, QR code exchange, or existing Bluetooth connection) that serve as mediators to establish initial trust between devices. These intermediaries enable the main Wi-Fi pairing process to occur automatically without direct user intervention.
2Adaptability or versatility
If multiple connection types are supported, then versatility is improved, but connection establishment complexity increases
Solution Approach 1:
The patent implements a universal pairing framework where a single authentication mechanism (established through alternative methods) can enable multiple connection types (Wi-Fi, Bluetooth, NFC). This multi-functional approach allows one pairing process to serve multiple connection purposes, reducing overall system complexity.
Solution Approach 2:
The pairing process is segmented into distinct phases: initial authentication through alternative methods, key exchange, and subsequent automated connection establishment. This segmentation allows each phase to be handled independently with appropriate methods, simplifying the overall multi-connection process.
3Extent of automation
If automated pairing is implemented, then user involvement is reduced, but security key management complexity increases
Solution Approach 1:
The system implements self-service key management where devices automatically perform key derivation and exchange using pre-shared keys or authentication data obtained through alternative pairing methods. The automated key management system handles cryptographic operations without user intervention, reducing complexity from the user perspective while maintaining security.

AI summary
Disclosed is a method for virtual pairing of a first peer device with a second peer device. In the method, a nonce is generated at the first peer device for use in virtually pairing the first and second peer devices to establish a first-type wireless connection. The nonce is forwarded from the first peer device to the second peer device over an already established second-type wireless connection between the first and second peer devices. At least one new key is generated from the nonce and a shared key for the already established second-type wireless connection. The first peer device is virtually paired with the second peer device using the at least one new key to establish the first-type wireless connection between the first and second peer devices.
