Communication Instrument Authenticity Verification in Layered Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems, such as those described in PTL 1, are unable to identify the managing instrument for an apparatus with an abnormality, especially in systems with layered configurations.
Innovation Solution
An information communication system that includes a communication instrument and a verification device, which verifies authenticity for each apparatus managed by the communication instrument. The system features a notification mechanism that reports abnormalities in authenticity to a verification device above the communication instrument, allowing identification of the managing instrument for affected apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication processing is executed for each apparatus individually, then authentication verification is performed, but the managing instrument for an apparatus with abnormality cannot be identified in layered system configurations
Solution Approach 1:
The patent introduces a communication instrument as an intermediary between apparatuses and the upper verification device. This communication instrument aggregates authentication results from multiple apparatuses and transmits them upward, enabling the verification device to identify which specific apparatus and its managing instrument have abnormalities without requiring direct individual processing of each apparatus.
Solution Approach 2:
The patent combines authentication results from multiple apparatuses managed by the same communication instrument into a single aggregated report. This merging allows the verification device to process multiple apparatuses efficiently while still maintaining the ability to trace abnormalities to specific apparatuses and their managing instruments through the structured report format.
2Reliability
If authentication is performed for each apparatus in a layered system, then security verification is achieved, but the system complexity increases making it difficult to trace abnormalities
Solution Approach 1:
The patent segments the authentication system into hierarchical layers: apparatuses at the bottom level, communication instruments at the intermediate level, and verification devices at the upper level. Each layer handles authentication for its subordinate elements and aggregates results before passing them upward. This segmentation reduces the complexity faced by any single component while maintaining comprehensive security verification across the entire system.
3Measurement precision
If individual apparatus authentication is implemented, then authenticity is verified, but information about the managing instrument is lost in branched configurations
Solution Approach 1:
The patent implements a feedback mechanism where the communication instrument receives authentication results from multiple apparatuses, processes this information, and provides structured feedback reports to the upper verification device. The feedback includes identification information that traces each apparatus back to its managing communication instrument, ensuring that no identification information is lost even in branched system configurations.
