摘　　要：数据库中的数据易成为黑客攻击的主要目标。加强数据库安全的首要方法就是数据加密存储。根据影响数据安全的加密粒度、加密层次、加密算法等因素的优缺点,提出了一种基于对称和非对称两种共用的加密算法数据库加密模型,该模型具有加密速度快、密钥管理方便的特点。数据库加密技术涉及操作系统、网络、信息安全等众多领域还存在不少技术瓶颈需要攻克。Data in database tends to be the main target of hacker attack.To store data in encrypted form is considered as the prime method to enhance database security.In this study,advantages and disadvantages of factors such as encryption granularity,encryption level,and encryption algorithm that affect data security are analyzed,and a database encryption model based on two common encryption algorithms,symmetric and asymmetric,is proposed.The model has fast encryption speed and convenient key management.As database encryption technology involves many fields such as operating system,network,information security,etc.There are still many technical bottlenecks to be overcome.
