基于区块链的工业控制系统数据防篡改研究 -安全工程专业

摘要

工业控制系统（ICS）作为现代工业的核心基础设施，其数据完整性与安全性至关重要。然而，传统工业控制系统面临日益严峻的数据篡改威胁，尤其是在网络攻击频发的背景下，如何有效保障数据的真实性和不可抵赖性成为亟待解决的问题。为此，本文提出一种基于区块链技术的工业控制系统数据防篡改方案，旨在通过区块链的分布式账本和共识机制提升数据的安全防护能力。研究结合工业控制系统的实际需求，设计了一种轻量级的区块链架构，并通过智能合约实现数据的实时验证与记录，确保数据在采集、传输和存储过程中的完整性。实验结果表明，该方案能够在不影响系统性能的前提下显著降低数据被篡改的风险，同时具备较高的可扩展性和兼容性。本文的主要创新点在于将区块链技术与工业控制系统深度融合，提出了适配性强的轻量化解决方案，为工业控制领域的数据安全提供了新思路。研究成果不仅验证了区块链技术在工业控制场景中的可行性，也为未来相关技术的应用与发展奠定了理论基础。

ABSTRACT

Industrial Control Systems (ICS), as the core infrastructure of modern industry, play a critical role in ensuring data integrity and security. However, traditional ICS face increasingly severe threats of data tampering, particularly in the context of frequent cyber-attacks. This has made it imperative to address the challenge of safeguarding data authenticity and non-repudiation effectively. To this end, this paper proposes a blockchain-based anti-tampering solution for ICS data, aiming to enhance data security through the distributed ledger and consensus mechanisms of blockchain technology. By integrating the practical requirements of industrial control systems, a lightweight blockchain architecture is designed, and real-time data validation and recording are implemented via smart contracts, thereby ensuring data integrity during acquisition, transmission, and storage. Experimental results demonstrate that the proposed solution significantly reduces the risk of data tampering without compromising system performance, while also exhibiting high scalability and compatibility. The primary innovation of this study lies in the deep integration of blockchain technology with ICS, proposing a highly adaptable lightweight solution that offers new insights into data security in the industrial control domain. The research not only verifies the feasibility of applying blockchain technology in industrial control scenarios but also lays a theoretical foundation for the future development and application of related technologies.
