NFC Handover Select Record for Secure Wi-Fi Direct Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for establishing wireless peer-to-peer connections, such as Wi-Fi Direct and NFC, are complex and time-consuming for users, often requiring manual configuration and security credential entry, which can deter users from connecting devices and completing actions like printing or sharing files.
Innovation Solution
A system using Near Field Communication (NFC) to read information needed for a peer-to-peer connection, enabling a handover select record that facilitates a secure Wi-Fi Direct connection between devices, allowing actions to be initiated automatically based on the context of the first device, such as printing a photo when tapped to a printer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration and security credential entry are required for wireless peer-to-peer connection, then connection security is improved, but user operation complexity and connection time increase
Solution Approach 1:
Security credentials and connection parameters are pre-configured in the handover select record stored on the second device. When NFC connection is established, these pre-prepared credentials are automatically transferred to the first device, eliminating the need for users to manually enter security information during the connection process.
Solution Approach 2:
The NFC connection acts as an intermediary channel to securely transfer handover select records containing authentication credentials between devices. This intermediary mechanism enables automatic authentication for the subsequent wireless peer-to-peer connection without requiring direct user interaction with security settings.
2Reliability
If manual configuration steps are required for wireless connection, then connection security is improved, but connection time increases
Solution Approach 1:
All necessary connection parameters including security credentials, network identifiers, and authentication information are pre-configured in the handover select record before the connection process begins. This preliminary preparation allows the actual connection to be established rapidly through automatic parameter transfer via NFC.
Solution Approach 2:
The system performs self-configuration by automatically transferring and applying connection parameters from the handover select record without requiring user intervention. The devices autonomously complete the connection setup process using the pre-configured information, significantly reducing connection time while maintaining security.
3Ease of operation
If automatic actions are initiated based on device context, then user convenience is improved, but device complexity increases
Solution Approach 1:
The handover select record pre-configures not only connection parameters but also context information about the first device's state and intended actions. This preliminary preparation enables the system to automatically determine and execute appropriate actions (such as printing or file transfer) based on the device context without requiring complex real-time analysis.
