Wireless Charging Pairing for Secure Cordless Telephone Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication pairing methods for desktop telephones are time-consuming, inconvenient, and insecure, particularly as they rely on Bluetooth protocols that expose devices to eavesdropping and man-in-the-middle attacks, and require additional NFC capabilities for secure out-of-band authentication, which is costly and complex to implement.
Innovation Solution
The use of a wireless charging system's data communication channel as an out-of-band channel for secure pairing between a telephone base and a wireless handset, leveraging the Wireless Power Consortium Qi Protocol to facilitate fast and secure pairing without the need for additional NFC capabilities or sensors, thereby simplifying the process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth protocol is used for wireless communication pairing, then wireless connectivity is established, but pairing process becomes time-consuming and insecure against eavesdropping and man-in-the-middle attacks
Solution Approach 1:
The patent introduces an out-of-band communication channel as an intermediary for secure pairing. This separate channel (distinct from the main Bluetooth communication channel) allows exchange of pairing credentials and authentication data, preventing eavesdropping and man-in-the-middle attacks on the primary communication path. The intermediary channel provides a secure foundation for establishing trusted wireless connectivity.
Solution Approach 2:
The patent adds a new dimension to the pairing process by utilizing a different communication medium or channel (out-of-band) rather than relying solely on the Bluetooth radio channel. This dimensional separation allows simultaneous secure authentication and communication setup, reducing overall pairing time while enhancing security through multi-channel verification.
2Reliability
If NFC capabilities are added for secure out-of-band authentication, then security is improved, but device complexity and cost increase
Solution Approach 1:
The patent makes the existing wireless communication interface multi-functional by using it for both data communication and secure pairing authentication. The same radio interface and protocol stack handle both operational communication and pairing credentials exchange, eliminating the need for dedicated NFC hardware while maintaining secure out-of-band authentication capabilities.
Solution Approach 2:
The system uses its own existing wireless communication infrastructure to provide the secure pairing function, rather than relying on external or additional specialized hardware. The out-of-band channel is created within the existing communication stack, allowing the device to authenticate itself using resources already present in the system.
3Ease of operation
If traditional pairing methods are used, then connectivity is established, but user interaction is required which reduces convenience
Solution Approach 1:
The patent performs pairing authentication actions in advance during the initial connection establishment. By pre-exchanging cryptographic credentials and establishing trust relationships before actual data communication begins, the system eliminates the need for user intervention during ongoing operations. The pairing is completed automatically as part of the connection handshake process.
Solution Approach 2:
The pairing process is automated through self-service mechanisms where devices automatically exchange credentials, verify authentication, and establish secure connections without requiring user input. The system handles the entire pairing sequence autonomously, improving both convenience and speed by eliminating manual user actions.
