摘　　要：研究了一种与应用系统相结合的数据库加密方法,旨在构建一种保护数据安全,实现应用与数据库的透明体验技术。分析了现有数据库加密安全技术存在的问题,在数据库系统服务缓存中构建一个安全容器和一个基础容器,使用密码服务策略组件实现数据库系统与应用系统和加密服务系统之间的加密信息通信和策略联动。解决了应用系统对重要数据的加密存储需求,同时不影响应用系统的其他功能体验。数据库依然保存着重要数据的密文,数据安全性、系统健壮性和服务响应性能等都优于现有的数据库加密技术;能够保证数据机密性,同时不影响现有数据库系统提供的全部功能服务,达到数据安全保密,体验无感知;而且应用范围广,只要有重要信息加密需求的应用系统都可以使用;此外,其也可用于数据交易、数据共享、隐私计算和数据合规安全要求的场景。A database encryption method combined with application systems is studied,and it aims to build a technology that protects data security and achieves transparent experience between applications and databases.The problems of existing database encryption security technol⁃ogy is analyzed,a security container and a basic container are constructed in database system ser⁃vice cache,and cryptographic service policy component are used to realize the encryption informa⁃tion communication and policy linkage between database system,application system and encryption service system.It solves the encryption and storage requirements of important data of application sys⁃tems without affecting the experience of other functions of the application system.The database still retains the ciphertext of important data,and its data security,system robustness,and service response performance are superior to existing database encryption technologies.It can ensure data confidentiality without affecting all functional services provided by the existing database system,achieve data security and confidentiality,and provide a seamless experience.Moreover,it has a wide range of applications and can be used by any application system that requires encryption of important information.In addition,it can also be used in scenarios involving data transactions,data sharing,privacy computing,and data compliance and security requirements.
