数据库加密系统设计研究

摘要

从增强数据库安全性出发,对数据库加密的层次、原理、算法和密钥管理等关键技术进行了分析研究,并研究了如何设计数据库加密系统,提出了一种数据库加密系统设计方案,给出了具体的设计模型并说明了各个功能模块的主要作用和实现方法,最后讨论了该加密系统对数据库的影响.%For the sake of enhancing the security of database, the article firstly analyzes the key technologies of encrypting database such as encrypting levels, encrypting principle, arithmetic, key management and so on.It also investigates into how to design a database encrypting system.Secondly, it puts forward a scheme of designing a database encrypting system.Then it puts forward the idiographic designing model and illuminates the main function and realization method of each module Lastly, it discusses the influence of the database encrypting system to the database.
