Single Pairing for Multiple Wireless Technologies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth and BLE technologies require multiple key exchanges for secure connections across different communication standards, leading to user annoyance and redundant security procedures when multiple technologies are used between the same pair of devices.
Innovation Solution
A mechanism to securely share long-term keys or their derivatives between different technologies in devices, allowing a single pairing to establish connections across multiple technologies, eliminating the need for multiple key exchanges and enhancing user experience by simplifying the security process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple key exchanges are performed for secure connections across different communication standards, then security is improved, but user experience deteriorates due to redundant security procedures and user annoyance
Solution Approach 1:
The patent merges multiple key exchange operations into a single unified key exchange. The system performs one key exchange between two devices and then reuses the exchanged key for securing multiple different communication technologies (Bluetooth, BLE, Wi-Fi Direct), eliminating redundant key exchanges and improving user experience while maintaining security across all technologies
Solution Approach 2:
The patent implements a universal key that serves multiple functions across different communication technologies. A single exchanged key is universally applied to secure connections for Bluetooth, Bluetooth Low Energy, and Wi-Fi Direct, making the security mechanism multi-functional and eliminating the need for technology-specific key exchanges
2Reliability
If multiple key exchanges are performed for secure connections across different communication standards, then security is improved, but connection time increases due to redundant procedures
Solution Approach 1:
The patent performs a preliminary key exchange that prepares for future connections across multiple technologies. The single key exchange is performed in advance and the resulting key is stored and reused for subsequent connections, eliminating the need for repeated key exchange operations and reducing connection time
Solution Approach 2:
The patent combines multiple key exchange operations into one unified operation. By merging the key exchange for Bluetooth, BLE, and Wi-Fi Direct into a single operation, the system eliminates redundant procedures and significantly reduces the total time required for secure connection establishment

AI summary
Various systems and methods for using single pairing for multiple technologies are provided herein. A system comprises a transceiver; a communication controller to interface with the transceiver and cause the transceiver to: connect to a remote device using a first protocol, the first protocol including a long term key for use in successive connections between the system and the remote device with the first protocol; and receive, from the remote device, a set of technologies supported by the remote device; and a security manager to: determine a set of common technologies; receive from the remote device, a set of tuples for each technology in the set of common technologies, each tuple comprising an identifier associated with the remote device for each technology and a corresponding technology; and create long term keys for use in later connections with the remote device using a technology from the set of technologies.
