Grid Telemetry Fingerprinting for Power Transaction Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The electrical grid is vulnerable to cyber attacks, making it difficult to verify that information provided by entities on the grid is genuinely coming from the grid and not from another location.
Innovation Solution
Generating a grid telemetry fingerprint based on characteristics such as voltage, phase angle difference, reactive power, and grid inertia, which is used to verify transactions and ensure that they originate from the correct section of the grid, preventing fraudulent instructions or information by comparing the fingerprint with the grid's actual fingerprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the grid uses interconnected networks for reliability and commercial purposes, then the coordination and planning of electricity supply is enhanced, but the vulnerability to cyber attacks increases
Solution Approach 1:
The patent introduces grid telemetry fingerprints as an intermediary verification mechanism. These fingerprints are generated from actual grid measurements (voltage, frequency, power flow) and serve as mediators to verify the authenticity of transactions. When a transaction is submitted, the system generates a fingerprint from current grid conditions and compares it with the fingerprint included in the transaction, ensuring the transaction originates from the claimed grid location without exposing the underlying grid infrastructure to direct attack vectors.
Solution Approach 2:
The patent transforms physical grid parameters (voltage, frequency, power flow measurements) into cryptographic fingerprints through hash functions. This parameter transformation converts continuous physical measurements into discrete verification tokens that can be used for security purposes without exposing the sensitive physical grid state, thus maintaining reliability while mitigating cyber vulnerability.
2Reliability
If the system verifies transactions using grid telemetry fingerprints, then security and integrity are enhanced, but the complexity of the verification process increases
Solution Approach 1:
The patent extracts only the essential verification information from complex grid telemetry data by generating condensed fingerprints through hash functions. Instead of verifying entire sets of grid measurements, the system extracts a single fingerprint value that represents the critical state of the grid at a given moment, significantly simplifying the verification process while maintaining security and integrity.
Solution Approach 2:
The patent creates cryptographic copies (fingerprints) of grid state information that can be easily transmitted and verified. These fingerprint copies contain the essential verification data without requiring access to the original complex telemetry datasets, reducing the computational and communication overhead of the verification process while ensuring transaction authenticity.
