Wireless Terminal Parameter Setting via Verification Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication parameter setting methods for wireless LAN devices require devices to stop operation, making them vulnerable to parameter interception and necessitate switching to default parameters, which can lead to security issues and operational disruptions.
Innovation Solution
A communication system and method where a first device transmits identification data to a second device upon initiating parameter setting, allowing the second device to determine registration status and set parameters only for the intended target device, enabling simultaneous parameter setting without interrupting ongoing operations and enhancing security by using encryption keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If communication parameters are set by transferring them automatically from access point to station using default parameters, then parameter setting becomes simpler, but the transmitted parameters may be intercepted by malicious third parties and security is compromised
Solution Approach 1:
The system performs preliminary actions by having the station generate communication parameters locally before transmission, and the access point store verification information in advance. This allows the station to prove its legitimacy without exposing the actual communication parameters to interception risks during transmission.
Solution Approach 2:
The invention introduces verification information as an intermediary mechanism. Instead of directly transmitting sensitive communication parameters, the system uses verification information (hash values or encrypted data) as a mediator to authenticate the station's legitimacy, thereby preventing parameter interception while maintaining automated setting capability.
2Reliability
If devices stop operation to set communication parameters, then parameter setting can be performed securely with device specification, but operational continuity is interrupted and productivity decreases
Solution Approach 1:
The system enables continuous operation by allowing parameter setting to occur without stopping device communication functions. The automated parameter generation and verification mechanism works in the background, maintaining operational continuity while completing the parameter setting process securely.
Solution Approach 2:
The station performs self-service by automatically generating its own communication parameters and providing verification information to the access point. This eliminates the need for manual intervention or device shutdown, allowing the device to maintain operational continuity while completing parameter setting autonomously.
3Extent of automation
If default communication parameters are used for parameter transfer, then parameter setting becomes automated, but the transmitted parameters may be intercepted and switching to default parameters disrupts ongoing communications
Solution Approach 1:
The system transforms the parameter transmission approach by changing from direct communication parameter transmission to verification information transmission. The station generates parameters locally and transmits only verification information (hash values or encrypted representations), fundamentally changing what is transmitted and eliminating interception vulnerabilities while maintaining automation.
Solution Approach 2:
Verification information serves as an intermediary that replaces direct communication parameter transmission. This intermediary mechanism allows automated parameter setting while preventing interception of actual communication parameters, as only non-sensitive verification data is transmitted between devices.
Data Source
AI summary
A wireless terminal which newly joins a wireless communication system transmits a message containing its identification data to an access point in the wireless communication system at a communication parameter setting start. Upon receiving the message, the access point determines whether or not the wireless terminal has been registered. If it is determined that the wireless terminal has not been registered, the access point determines whether or not the wireless terminal is a setting target device of communication parameters based on the identification data contained in the message. If it is determined that the wireless terminal is a setting target device, the access point sets communication parameters for the wireless terminal.
