　　摘 要：水利行业各级政府网站所发布的信息应该及时、准确、权威，信息一旦被篡改，将会严重影响国家安全，损坏水利政府部门公信力和形象，传统防篡改系统存在默认信任特定节点，底稿存储不可靠等问题。为更好地保障水利行业政府网站信息安全，降低入侵风险，通过研究区块链的分布式记账原理和可信去中心化特点，提出一种基于区块链和分布式存储的新型防篡改系统。利用区块链的去中心化的信任机制和分布式存储的安全性，新型防篡改系统能够消除单点薄弱环节，可靠存储底稿文件，不需信任特定节点。测试结果表明：与传统防篡改系统相比，新型防篡改系统能够更好地满足水利行业政府网站在防篡改领域的需求，保证水利行业政府网站发布的内容得到有效保护，保护水利行业政府网站免遭篡改的侵害。

　　Abstract: The information published by government websites in the water conservancy industry should be timely, accurate, and authoritative. It will bring bad effects on national security and ruin the image of the government public credibility once the information is tampered with. Traditional tamper-proof systems have problems such as trusting specific nodes by default and unreliable storage of the original documents. In order to ensure government website information safety in the water conservancy industry and reduce the risk of invasion, a new tamper-proof system based on blockchain and distributed storage has been proposed by studying the distributed ledger and decentralized trust of blockchain. Using the decentralized trust mechanism of blockchain and the security of distributed storage, the new temper-proof system can eliminate single weak links, reliably store draft files and need not to trust specific nodes. The test result shows that compared with traditional tamper-proof systems, the new temper-proof system can better meet the anti-tampering demand of government websites, ensure the content published by government websites in the water conservancy industry protected effectly, and protect government websites in the water conservancy industry from tampering.
