Zero-Knowledge Range Proofs and Blockchain Integration for Enhancing SCADA Data Security

Traditional Supervisory Control and Data Acquisition (SCADA) are prone to cyber attacks which makes it difficult in keeping data secure. As the traditional architecture relies on centralized storage, which makes them vulnerable to unauthorized access and manipulation. To tackle these security concerns, the study demostrates the integration of blockchain technology and Bulletproof, a zero-knowledge range proof technique into SCADA systems to securely store aggregated sensor value proof in the ledger. The study uses Hyperledger fabric, creating a transparent and tamper-proof record for audits and providing a more secure and trustworthy system. This approach reduces storage and computational overhead while ensuring that data remains private and within valid ranges without exposing sensitive details. By combining blockchain with zero-knowledge range proofs, the proposed solution enhances both security and efficiency in SCADA systems. It ensures that sensor data remains protected from tampering while keeping blockchain resources optimized. This makes industrial systems more secure, reliable, and ready for the future of automation.
