摘 要
随着云计算技术的迅猛发展，数据存储和处理逐渐向云端迁移，但云环境下的数据安全问题日益凸显，数据库加密技术成为保障数据安全的关键手段。本研究聚焦于数据库加密技术在云计算环境中的应用与挑战，旨在探索有效的加密方案以确保数据的机密性、完整性和可用性。通过文献综述与案例分析相结合的方法，系统梳理了当前主流的数据库加密算法及其在云环境中的适用性，重点考察了透明加密、同态加密等关键技术的应用场景及局限性。研究发现，传统加密方法难以直接适用于云计算架构，存在性能损耗大、密文操作复杂等问题。为此，本文提出一种基于属性基加密的改进方案，该方案不仅实现了细粒度访问控制，还有效降低了加密开销，在保证数据安全的同时兼顾了系统的高效运行。

Abstract
With the rapid development of cloud computing technology, data storage and processing have gradually migrated to the cloud, but the data security problems in the cloud environment have become increasingly prominent, and database encryption technology has become a key means to ensure data security. This study focuses on the application and challenges of database encryption technologies in the cloud computing environment, and aims to explore effective encryption schemes to ensure the confidentiality, integrity, and availability of data. Through the method of combining literature review and case analysis, the current mainstream database encryption algorithm and its applicability in the cloud environment are systematically reviewed, and the application scenarios and limitations of key technologies such as transparent encryption and homomorphic encryption are mainly investigated. It is found that the traditional encryption method is difficult to directly apply to cloud computing architecture, and there are problems such as large performance loss and complex ciphertext operation. Therefore, this paper proposes an improved scheme based on attribute base encryption, which not only realizes fine-grained access control, but also effectively reduces the encryption overhead, ensuring data security while taking into account the efficient operation of the system.
