Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless LAN relay devices require complex security settings, necessitating user knowledge of encryption techniques, making them difficult for non-technical users to secure communications effectively.
Innovation Solution
A wireless LAN relay device that initially communicates without encryption and automatically encrypts packets using pre-defined encryption keys and methods upon receiving a setting instruction from an outer device, simplifying security settings through predefined encryption keys and methods stored within the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption is implemented on wireless LAN relay device, then communication security is improved, but device complexity and ease of operation deteriorate due to required security settings knowledge
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple encryption keys and encryption methods in the wireless LAN relay device before actual use. The device contains a storage unit that holds encryption keys and encryption methods in advance, and an encryption unit that automatically selects and applies the appropriate encryption settings when communication is established, eliminating the need for users to perform complex security configurations.
2Adaptability or versatility
If manual security settings are required, then encryption customization is improved, but ease of operation deteriorates due to need for user knowledge
Solution Approach 1:
The patent applies self-service by enabling the wireless LAN relay device to automatically manage its own encryption settings. The device includes an encryption unit that autonomously selects encryption methods and keys from pre-stored options, and a control unit that manages the encryption process without requiring user intervention. This allows the device to serve itself in configuring security parameters while maintaining multiple encryption options for different communication scenarios.

AI summary
A wireless LAN relay device connecting an outer device to a network includes a communication section for controlling wired communication and wireless communication performed between the wireless LAN relay device and the outer device using a packet. The communication section performs, in an initial state, wireless communication without encrypting the packet, and encrypts, upon reception of a setting instruction from the outer device, the packet by using a predetermined encryption key and a predetermined encryption method which are preliminarily defined in the wireless LAN relay device.
