摘要
数据库系统的信息安全性已成为目前迫切需要解决的课题。本文介绍一种基于字段加密,动态分配密钥的新型的加密方法,这种方法较好地解决了不同用户对数据加密的不同要求,妥善地处理好了加密强度与数据库系统性能之间的矛盾,具有一定的实际意义。
How to manage the information security has become a problem we must settle exactly. A new technique of database encryption based on encrypting fields and dynamically distributing key is provided, this technique can solve diverse requests of different users and deal with the contradiction between encryption intensity and capability of database system. It has definite practicability.
