Illumination Communication Pairing with Random Code Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination and communication systems require user-dependent operations and are not secure against unexpected connections, lacking adaptability to various communication standards and ensuring exclusive communication.
Innovation Solution
A communication system where a slave device generates random number-based key and security codes, which are exchanged and retained by a master device, and communication is terminated if the codes do not match, ensuring secure connections without user operations or platform dependency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user operations are required for registration and pairing, then device control can be established, but the system becomes dependent on user actions and less secure against unexpected connections
Solution Approach 1:
The slave device automatically generates and transmits its identification information without requiring user intervention. The system performs self-registration and self-pairing operations, eliminating dependency on user actions while maintaining secure connections through automatic code generation and verification
Solution Approach 2:
The slave device pre-generates identification information including random numbers and security codes before communication establishment. This preliminary preparation allows the device to securely connect without waiting for user operations, improving both security and ease of operation
2Reliability
If connection control is performed with security verification, then secure communication is achieved, but the complexity of the communication protocol increases
Solution Approach 1:
The security verification process is divided into distinct phases: first processing for code generation and transmission, and second processing for code verification and connection termination. This segmentation makes the complex security protocol more manageable and implementable while maintaining high security standards
Solution Approach 2:
The system uses random numbers as variable parameters to generate unique identification information and security codes for each connection. This parameter-based approach provides strong security without requiring complex cryptographic protocols, simplifying the overall system while maintaining reliability
3Reliability
If platform-specific pairing methods are used, then secure pairing can be achieved, but adaptability to different communication standards is reduced
Solution Approach 1:
The slave device generates identification information using universal random number generation that can be interpreted by different communication standards. The security code verification mechanism works across multiple platforms without requiring platform-specific pairing procedures, achieving both security and adaptability
Solution Approach 2:
The system introduces a universal identification information format as an intermediary between different communication standards. This intermediary layer allows secure pairing while maintaining compatibility across various platforms and communication protocols, resolving the conflict between security and adaptability

AI summary
A communication system is configured to transmit and receive control data between a master device and a slave device. the slave device generates a first key code and a first security code. in first processing after communication connection between the slave device and the master device is established, the master device received the first key code and the first security code from the slave device, and retains the first key code as a second key code and retains the first security code as a second security code. And in second processing after the first processing, the slave device terminates the communication connection with the master device in a case where a first code generated by the slave device and a second code received from the master device do not match.
