Router Dynamic Password Authentication for Public WiFi Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current public WiFi connections using unencrypted methods allow numerous idle or unauthorized terminal devices to maintain active sessions, leading to slow router operation and poor Internet experience.
Innovation Solution
Implement a network connection method involving dynamic passwords exchanged between a router and a mobile terminal, with verification and subsequent clearing of connection information after successful authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If unencrypted connection method is used for public WiFi, then connection establishment is simple and fast, but resource consumption increases due to excessive connection sessions from idle or unauthorized devices
Solution Approach 1:
The patent implements preliminary authentication actions before allowing connection. The router sends a first dynamic password to the terminal device, which then sends a second dynamic password to the router for verification. This preliminary verification ensures only authorized devices establish connections, preventing resource consumption by idle or unauthorized devices while maintaining simple connection establishment.
Solution Approach 2:
The patent changes the connection parameters from static preset keys to dynamic passwords that are generated and verified during the connection process. The router and terminal device exchange dynamic passwords that change with each connection session, ensuring security while allowing simple user interaction. This parameter change prevents resource waste while maintaining ease of operation.
2Loss of energy
If dynamic password verification is implemented, then resource consumption is reduced by preventing unauthorized connections, but connection establishment process becomes more complex
Solution Approach 1:
The patent introduces a server as an intermediary that facilitates the dynamic password verification process. The server receives the first dynamic password from the router and the second dynamic password from the terminal device, then performs verification. This intermediary approach simplifies the complexity by centralizing the verification logic, making the connection process more manageable while reducing resource consumption from unauthorized connections.
Solution Approach 2:
The patent implements feedback mechanisms where the router sends the first dynamic password to the terminal device, which then sends the second dynamic password back to the router for verification. This feedback loop ensures proper authentication while maintaining a relatively simple user experience. The system provides clear feedback on connection status, making the verification process transparent and manageable.
3Reliability
If connection information is cleared after successful authentication, then unauthorized reconnections are prevented, but connection stability decreases
Solution Approach 1:
The patent applies dynamics by clearing connection information after successful authentication, which dynamically changes the connection state from established to cleared. This dynamic approach prevents unauthorized reconnections and maintains security while allowing legitimate users to maintain stable connections through proper authentication. The system adapts connection management based on authentication status, balancing security and stability.

AI summary
Provided are a router, a network connection method and a mobile terminal. The network connection method comprises: a router receiving a first dynamic password from a server; the router receiving a second dynamic password from a mobile terminal, and performing matching on the basis of the second dynamic password and the first dynamic password; if the matching is successful, establishing a connection, and sending a first result signal to the mobile terminal; and the router purging connection information associated with the connection after the connection has been established. The invention can prevent an unauthenticated terminal from connecting to a router, thereby enhancing the security of a connection established by means of a router.
