Master Device Network Participation Denial for Secure Parameter Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, such as IEEE 802.11x compliant wireless LANs, face challenges in securely configuring communication parameters due to the risk of spoofing by third parties and the complexity of configuration processes, which can lead to unnecessary device participation and information leakage.
Innovation Solution
Implementing a denial mechanism for new communication devices to participate in network configuration based on their participation status and capability information, establishing a secure communication parameter configuration network by determining a master device and restricting participation, and encrypting communication to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless communication devices communicate directly with each other in an ad hoc network to configure communication parameters, then configuration convenience is improved, but security against spoofing by third parties deteriorates
Solution Approach 1:
The patent applies preliminary anti-action by establishing participation status verification mechanisms before configuration begins. The master device checks whether attempting devices are already participating in the ad hoc network, and denies participation to devices that are not currently participating. This pre-emptive check prevents spoofing attempts before they can compromise the configuration process, while still allowing legitimate devices to configure parameters conveniently.
2Adaptability or versatility
If the network allows new communication apparatuses to participate freely during configuration, then configuration flexibility is improved, but information leakage to unauthorized devices increases
Solution Approach 1:
The patent applies local quality by implementing differentiated access control based on participation status. Devices with legitimate participation status (those already connected to the ad hoc network) are granted full configuration flexibility and can freely join the configuration process. Devices without proper participation status are denied access, preventing information leakage. This creates localized security zones within the network where access rights vary by device status.

AI summary
A communication apparatus functioning as a master device denies participation by new communication apparatuses in a network in communication parameter configuration mode based on participation statuses of communication apparatuses functioning as slave devices in the network. The communication apparatus functioning as a master device establishes the network in communication parameter configuration mode between the communication apparatuses participating in the network, and configures communication parameters.
