Auto Provisioning Method for Wireless Network Security Key Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Wi-Fi network provisioning methods, such as WPS, require user intervention and knowledge to manually enter security information like PIN codes, making the process cumbersome and not user-friendly.
Innovation Solution
An auto provisioning method that involves receiving a request from a station, verifying it with a code, sending a response, retrieving a security key from a security message, and executing network provisioning automatically, eliminating the need for manual user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual provisioning method is used, then user control over security configuration is maintained, but user friendliness and setup time are worsened
Solution Approach 1:
The patent implements self-service by enabling the communication device to automatically retrieve and execute network provisioning without user intervention. The device autonomously searches for authentication servers, exchanges security messages, retrieves security keys, and configures network parameters, eliminating the need for users to manually search for and enter PIN codes or other security information.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the communication device with necessary authentication parameters and security settings before actual network joining. The device is equipped with verification codes and security message handling capabilities in advance, allowing it to automatically complete the provisioning process without requiring users to perform manual setup actions.
2Loss of time
If automatic provisioning is implemented, then setup time is reduced, but security verification complexity increases
Solution Approach 1:
The patent introduces an authentication server as an intermediary that handles complex security verification processes. Instead of the communication device performing complex verification locally, the authentication server mediates the security exchange by receiving verification codes, validating authentication parameters, and returning security keys, thereby simplifying the verification process for the end device while maintaining security.
Solution Approach 2:
The patent replaces manual mechanical operations (users physically typing PIN codes, navigating menus) with automated electronic communication processes. The verification code exchange and security key retrieval are handled through structured message protocols between devices and authentication servers, substituting complex manual verification procedures with automated digital communication that is both time-efficient and security-maintaining.

AI summary
A method for auto provisioning for a communication device in a wireless communication network comprises the steps of: receiving a request from a station; determining the validity of the request according to a verification code carried by the request; sending a response to the station; receiving a security message from the station; retrieving a security key carried by the security message; and executing network provisioning according to the security key.
