摘要
在对数据库加密的层次,加密粒度,加密算法等技术进行分析和研究的理论基础上,设计了一套适用于网络数据库的加密系统,该加密系统采用基于数据项加密的方式对数据库中的敏感数据进行加密处理,在该加密系统中,引入了对称密钥和非对称密钥相结合的混合加密方式,并对系统密钥进行了有效、安全的多级化管理,该加密系统在一定程度上解决了数据库中敏感数据面临的安全问题。
Based on the analysis and research of the level of database encryption,the encryption granularity,the encryption algorithm,the paper has designed an encryption system that applies to network database.This encryption system carries on encryption processing to the sensitive data with the method based on the data item.This system adopts a mixed encryption model combining symmetric keys and asymmetric keys,which provides an effective and secure multilevel management for system encryption-keys.To a certain extent,this system has also solved the security problems which the sensitive data in the database face.
