Measurement Message Validation Using Device ID Whitelisting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement devices lack a reliable method for forming and validating messages, especially in decentralized systems, which is crucial for ensuring the integrity and accuracy of custody transfer transactions involving significant mass values, as stakeholders rely on trust-based records that may be unreliable.
Innovation Solution
A method and system for forming and validating messages from measurement devices using a decentralized network data gateway, which includes obtaining a unique identification and combining it with measurement data, and comparing it against a whitelist to ensure authenticity and integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement devices rely on trust-based records from customers acting as intermediaries, then existing systems can operate with simpler structures, but the reliability and integrity of measurement data cannot be ensured
Solution Approach 1:
The measurement device performs self-identification by generating and attaching its own unique identification to measurement data, eliminating the need for customer intermediaries to provide trust-based records. The device independently proves its identity and authorization status.
Solution Approach 2:
A decentralized network gateway serves as a neutral intermediary that receives measurement data from devices, validates their unique identifications against whitelists, and forwards verified data to recording systems. This mediator ensures data integrity without requiring customer involvement.
2Reliability
If a unique identification system with whitelisting is implemented, then the integrity of measurement data is improved, but the complexity of the system increases
Solution Approach 1:
Instead of using complex cryptographic signatures or digital certificates, the system uses simplified unique identification values (such as serial numbers or device IDs) that are copied and stored in a whitelist. This copying approach maintains integrity while reducing technical complexity.
Solution Approach 2:
Device identifications are pre-validated and stored in a whitelist by the decentralized network gateway before measurement data is collected. This preliminary action ensures that only authorized devices can contribute data, simplifying runtime validation to a straightforward comparison.
3Reliability
If measurement devices do not include unique identification, then the device structure remains simple, but the ability to validate and ensure data authenticity is compromised
Solution Approach 1:
The unique identification is extracted as a separate, standalone element from the measurement data structure. This allows the identification to be added with minimal impact on the core measurement functionality, as it operates independently as a verification layer.
Solution Approach 2:
The unique identification serves multiple functions: it identifies the device, proves authorization status, and enables validation by the decentralized network gateway. This multi-functionality reduces the need for separate validation mechanisms, keeping the overall system simple.
