Wireless Communication Device Password Generation for Network Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies do not provide a secure method for constructing a new wireless network after the previous one has disappeared, as they do not ensure that the new network's password is unknown to unauthorized third parties, potentially allowing illegal participation.
Innovation Solution
A wireless communication device that can operate in either a parent or child state, creating a new password for the new network that is different from the previous one, and optionally not creating a password when operating in the child state, ensuring security by preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wireless communication device reuses the same password for a new wireless network after the previous network has disappeared, then the ease of operation is improved (users don't need to remember new passwords), but the security deteriorates (third parties can illegally participate using the old password)
Solution Approach 1:
The patent changes the password parameter when constructing a new wireless network after the previous network has disappeared. The creating unit generates a new password that is different from the previous password, ensuring that even though the network SSID remains the same, the authentication credentials are updated. This resolves the contradiction by maintaining security through parameter change while still providing ease of operation through automatic password management.
2Reliability
If the wireless communication device creates a new password for the second wireless network, then the security is improved (third parties cannot illegally participate), but the device complexity increases (need to manage password creation and differentiation)
Solution Approach 1:
The patent implements self-service by automatically generating and managing passwords through the creating unit. The device autonomously creates new passwords for subsequent wireless networks without requiring manual user intervention. This resolves the contradiction by maintaining high security through automatic password generation while minimizing the perceived device complexity for the user, as the complexity is handled internally by the system.
Solution Approach 2:
The creating unit serves multiple functions: it generates passwords for initial network construction, creates new passwords for subsequent networks, and ensures password differentiation. This multi-functionality resolves the contradiction by consolidating password management tasks into a single universal component, maintaining security while reducing overall system complexity.
3Productivity
If the wireless communication device automatically determines to operate in parent state for new network construction, then the productivity is improved (faster network setup), but the device complexity increases (need to determine and manage parent/child states)
Solution Approach 1:
The determination unit automatically determines the operational state (parent or child) without requiring manual user configuration. This self-service approach resolves the contradiction by improving productivity through automatic state determination while managing the complexity internally within the determination unit, so users benefit from fast setup without needing to understand the underlying state management complexity.
4Reliability
If the wireless communication device creates different passwords for each new wireless network, then the security is improved (prevents illegal participation), but the loss of information increases (users must manage multiple different passwords)
Solution Approach 1:
The system automatically manages and stores the different passwords for each wireless network through the creating unit. When users need to connect to a network, the device autonomously provides the appropriate password without requiring users to manually remember or manage multiple passwords. This resolves the contradiction by maintaining security through password differentiation while eliminating the burden of password management for users.

AI summary
In a case where a first wireless network is to be constructed, and it is determined that a wireless communication device (10) is to operate in a parent state, the wireless communication device (10) may create first authentication information, and construct the first wireless network by executing a communication for establishing a wireless connection with a first external device (60) by using a first wireless profile including the first authentication information. In a case where a second wireless network is to be constructed after the first wireless network has disappeared, and it is determined that the wireless communication device (10) is to operate in the parent state, the wireless communication device (10) may create second authentication information, and construct the second wireless network by executing a communication for establishing a wireless connection with a second external device (60) by using a second wireless profile including the second authentication information.
