Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for connecting to wireless local area networks (WLANs) via WiFi access points are manual and cumbersome, requiring users to search for signals and input passwords, lacking automation and efficiency.
Innovation Solution
A method and system that automatically detect WiFi signals, compare them with prestored information, send encrypted password requests to an application server, and decrypt verification information to facilitate seamless network access, reducing the complexity and time required for connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual connection method is used, then user can control connection process, but connection complexity increases and automation decreases
Solution Approach 1:
The patent applies preliminary action by pre-storing WLAN information (including encrypted passwords) in the terminal before connection is needed. When a connection request occurs, the terminal automatically retrieves and uses the pre-stored information to complete authentication, eliminating the need for real-time password input and achieving automated connection while reducing process complexity
Solution Approach 2:
The terminal performs self-service by automatically detecting WLAN signals, comparing them with pre-stored information, retrieving encrypted passwords, and completing authentication without user intervention. The system serves itself by managing the entire connection process autonomously, including automatic decryption and password submission
2Productivity
If password input is required, then security verification is achieved, but operation time increases
Solution Approach 1:
The patent eliminates password input time by pre-storing encrypted passwords in the terminal before connection is needed. When authentication is required, the system automatically retrieves the pre-stored encrypted password and submits it for verification, reducing the connection process from multiple manual steps to an automated single-action operation
Solution Approach 2:
The patent extracts the password input task from the user's manual operations and transfers it to the system's automatic processes. The terminal extracts the encrypted password from its pre-stored information database and automatically submits it for authentication, completely removing the need for user interaction during connection
3Reliability
If encrypted password transmission is used, then security is improved, but system complexity increases
Solution Approach 1:
The patent introduces an application server as an intermediary that manages the distribution of encrypted passwords to terminals. The server acts as a mediator between the WLAN authentication system and user devices, storing and providing encrypted credentials without requiring complex encryption/decryption infrastructure at the terminal level, thus maintaining security while simplifying the overall system architecture
Solution Approach 2:
The system uses copying by distributing encrypted password copies from the application server to multiple terminals. Each terminal receives a copy of the encrypted authentication credentials needed for verification, eliminating the need for complex real-time encryption processes at each device while maintaining security through the use of encrypted copies
