Wireless Communication Apparatus Non-Readable SSID Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems using highly readable SSIDs for wireless LAN connections compromise security, as they are easily identifiable and shareable, especially when using technologies like Near Field Communication and Bluetooth Low Energy.
Innovation Solution
A communication apparatus with a control unit that manages two communication methods: one generating a network identified by a character string for easy user recognition and another generating identification information without using a character string, sharing it to create a network for secure communication with external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a highly readable SSID including character strings is used for wireless LAN connection, then ease of identification and user friendliness is improved, but security deteriorates because the network becomes easily identifiable and shareable
Solution Approach 1:
The patent segments the connection process into two distinct phases: a setup phase using readable SSIDs for initial network establishment, and a handover phase using non-readable SSIDs for secure communication. This segmentation allows each phase to use the appropriate SSID type for its specific purpose, resolving the contradiction between readability and security.
Solution Approach 2:
The patent performs preliminary network establishment using readable SSIDs before the handover to non-readable SSIDs. The initial network setup with character string-based SSIDs enables easy device identification and connection, while subsequent handover to non-readable SSIDs secures the communication channel, preventing unauthorized access.
2Ease of operation
If communication parameters are shared using Near Field Communication or Bluetooth Low Energy, then wireless LAN connection simplification is improved, but security deteriorates due to automatic network search and participation
Solution Approach 1:
The patent uses readable SSIDs as an intermediary during the initial connection phase, enabling simplified device discovery and connection through automatic network search. After the intermediary phase completes its purpose of facilitating connection, the system transitions to non-readable SSIDs for secure communication, eliminating the security vulnerability while maintaining the benefit of simplified initial connection.
3Reliability
If a non-readable SSID is used for network handover, then security is improved by reducing unauthorized connections, but ease of identification deteriorates
Solution Approach 1:
The patent implements dynamic SSID management where the SSID characteristics change based on the connection phase. During the initial setup phase, readable SSIDs are used for easy identification. During the handover and communication phase, non-readable SSIDs are used for security. This dynamic adaptation allows the system to optimize for different requirements at different times, resolving the contradiction between readability and security.
