Dual Wireless Device Pairing via Secure Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing pairing procedures for wireless communication devices, such as Bluetooth, are often inconvenient and require significant user effort, especially when multiple devices need to be paired with a mobile device for secure and encrypted communication.
Innovation Solution
A method where a first wireless communication device establishes a secure communication channel with a mobile device through a first pairing procedure, which is then used to perform an out-of-band pairing procedure for a second wireless communication device, reducing the need for user interaction and simplifying the pairing process without compromising security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional pairing procedure is performed for each wireless communication device separately, then security is maintained, but user effort and time consumption increase
Solution Approach 1:
The first pairing procedure between the first wireless communication device and the mobile device is performed in advance to establish a secure communication channel. This preliminary action enables the second wireless communication device to use the same channel for its pairing procedure, eliminating the need for a separate pairing process and reducing user effort while maintaining security through the pre-established encrypted channel.
2Adaptability or versatility
If separate wireless communication devices are used for different functionalities, then functional versatility is improved, but pairing complexity increases
Solution Approach 1:
The first wireless communication device serves multiple purposes: it establishes the initial secure channel for keyless access functionality and simultaneously provides the communication channel for the second wireless communication device's pairing procedure. This universal use of the first device's communication channel simplifies the overall pairing process while supporting multiple functional devices.
Solution Approach 2:
The first wireless communication device acts as an intermediary for the second wireless communication device's pairing procedure. By using the first device's established communication channel to exchange pairing information with the mobile device, the system reduces the complexity of pairing multiple devices without requiring direct interaction between each device and the mobile device.
3Reliability
If user input is required for each pairing procedure, then security confirmation is ensured, but ease of operation decreases
Solution Approach 1:
The second pairing procedure leverages the pre-established communication channel from the first pairing procedure, allowing the system to automatically exchange pairing information without requiring additional user input. The secure channel is already in place, so the second device can proceed with pairing autonomously using the existing secure pathway.
