数据库加密关键技术研究

Research on Key Techniques about Database Encryption

在分析数据库加密关键技术的基础上,由于在数据库加密时难以采用直接分发密钥给用户的方式,所以提出一种将密钥管理与智能卡和指纹识别技术相结合的方法,对于提高关系数据库安全具有一定作用。

Because it is unfeasible to directly distribute keys to users,a key management method that is incorporated will smart card and fingerprint identify is presented,By importing security dictionary and presenting an improved user authentication model,not only the high system security is ensured,but also users can access encrypted data expediently and session key exchange is achieved simultaneously.
