基于区块链的数据库数据安全策略
摘 要
随着信息技术的迅猛发展，数据安全问题日益凸显，传统数据库面临诸多挑战，如数据篡改、隐私泄露等。基于区块链的数据库数据安全策略旨在利用区块链技术不可篡改、分布式账本等特性保障数据安全。本研究聚焦于构建一种融合区块链与现有数据库系统的新型架构，以实现更高效可靠的数据保护机制。通过深入分析区块链技术原理及其在数据存储方面的优势，提出了一种基于智能合约的访问控制模型，该模型能够根据预设规则自动执行权限验证，确保只有授权用户才能进行特定操作。同时，设计了适用于不同类型数据的安全加密算法，结合哈希函数保证数据完整性。实验结果表明，在性能方面，尽管引入区块链会带来一定计算开销，但通过对共识算法优化，整体响应时间仍处于可接受范围内；安全性上，成功抵御了多种攻击方式，包括SQL注入、DDoS攻击等。

Abstract
With the rapid development of information technology, data security is increasingly prominent, and traditional databases face many challenges, such as data tampering, privacy leakage and so on. The blockchain-based database data security strategy aims to ensure data security by using blockchain technology and distributed ledger. This study focuses on building a new architecture that integrates blockchain with existing database systems to achieve a more efficient and reliable data protection mechanism. Through in-depth analysis of blockchain technology principles and their advantages in data storage, a smart contract-based access control model is proposed, which can automatically perform permission verification according to preset rules, and ensure that only authorized users can perform specific operations. At the same time, the secure encryption algorithm suitable for different types of data is designed to ensure the data integrity combined with the hash function. The experimental results show that in terms of performance, although the introduction of blockchain will bring some computing overhead, the overall response time is still within the acceptable range by optimizing the consensus algorithm; in security, it has successfully resisted various attacks, including SQL injection and DDoS attack.
