Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing M2M device configuration processes face challenges in ensuring security, particularly when the number of devices is large, as wireless communication channels are vulnerable to snooping, and managing encryption parameters for each device is cumbersome.
Innovation Solution
A configuration provision device equipped with an electronic paper display, an input device, and a controller that detects user actions to display configuration data, including digital security keys, as barcodes or using steganography, providing a secure and intuitive method for presenting configuration information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If configuration data is transmitted wirelessly for M2M device setup, then ease of operation is improved, but security is worsened due to vulnerability to snooping
Solution Approach 1:
The patent introduces an electronic paper display as an intermediary medium to present configuration data. Instead of directly transmitting sensitive configuration data wirelessly, the system displays it on an e-paper screen that can be physically inspected, thereby mediating between the secure storage and the need for configuration access while preventing wireless interception
Solution Approach 2:
The configuration data is copied onto an electronic paper display for visual presentation. This creates a physical copy that can be read without transmitting the actual data wirelessly, allowing configuration information to be accessed while maintaining security by keeping the original data protected in non-transmissible form
2Object-affected harmful factors
If encryption parameters are configured for each M2M device to ensure security, then security is improved, but device complexity increases due to manual configuration requirements
Solution Approach 1:
The system enables self-service configuration by automatically generating and displaying configuration data on the electronic paper display. The M2M device can autonomously present its configuration parameters without requiring manual intervention or complex setup procedures, thereby maintaining security while reducing configuration complexity
Solution Approach 2:
The electronic paper display serves multiple functions: it displays configuration data, presents security keys, and provides a secure interface for data transfer. This multi-functional approach consolidates what would otherwise require multiple separate configuration tools and procedures into a single universal device
3Object-affected harmful factors
If configuration data is displayed on electronic paper display for security, then security is improved, but ease of operation is worsened due to limited display capabilities
Solution Approach 1:
The system creates a visual copy of configuration data on the electronic paper display that can be easily captured by standard imaging devices. This copy function bridges the gap between secure display and user-friendly interaction, allowing users to capture configuration information using common devices like smartphones without compromising the security of the original data
