摘 要
随着信息技术的迅猛发展，网络故障数据保护成为信息安全领域的重要课题。数据库加密技术在网络故障数据保护中具有不可替代的作用。本研究旨在探讨数据库加密技术在网络故障数据保护中的应用，以提升网络故障数据的安全性。首先分析了当前网络环境下故障数据面临的威胁，如恶意攻击、数据泄露等，指出传统保护方法存在诸多局限，难以满足日益增长的安全需求。为此，提出基于属性基加密与同态加密相结合的数据库加密方案，该方案不仅能够实现对网络故障数据的细粒度访问控制，确保只有授权用户可解密读取数据，而且支持在加密状态下进行特定运算，保证数据处理效率。通过构建实验环境模拟实际网络故障场景并实施测试，结果表明所提方案在网络故障发生时能有效保护数据安全，相较于传统方法，在数据保密性、完整性方面有显著提升，且性能损耗处于可接受范围。

Abstract
With the rapid development of information technology, network fault data protection has become an important subject in the field of information security. Database encryption technology has an irreplaceable role in network fault data protection. The study aims to explore the application of database encryption technology in network fault data protection to improve the security of network fault data. First of all, this paper analyzes the threats of fault data in the current network environment, such as malicious attacks, data leakage, etc., and points out that the traditional protection methods have many limitations, which are difficult to meet the growing security needs. To this end, a database encryption scheme based on the combination of attribute base encryption and homomorphic encryption is proposed. This scheme can not only realize the fine-grained access control of network fault data, and ensure that only authorized users can decrypt the read data, but also support specific operations in the encryption state to ensure the efficiency of data processing. By constructing the experimental environment to simulate the actual network failure scenario and implementing the test, the results show that the proposed scheme can effectively protect the data security when the network failure occurs. Compared with the traditional method, the data confidentiality and integrity are significantly improved, and the performance loss is in an acceptable range.
