基于网络应用的数据库加密系统问题刍议

Web-based Applications,the Problem of Database Encryption System

该文针对以上这些问题,在针对数据库基于网络应用模式,对如何保证其中数据的私密性和对数据操作的有效性上,提出了一种加密数据可以直接进行搜索或查询的新方法,并根据研究结果对该算法中的加密方法进行了设计与实现。这些结果不仅可用于数据库应用,也可用于其它应用的加密数据的存储、访问、保密性要求的场合,如:记录日志的安全保护、电子邮件的安全保护等。

As a result,on the basis of network,we work out and deeply research a kind ofnew method that can directly research or query on encrypted data so that we caneffectively protect the data privacy and guarantee efficiency in database.And accordingto the results of the research,we realize the encryption in a fact model.At the same time,these results can be applied not only to database,but also to the saving encrypted data,accessing encrypted data and confidentiality of other fields,such as the secureprotection of logs,the secure protection of e-mail,and so on.
