浅谈Visual FoxPro数据库系统的加密技术

Shallow talk that the Visual FoxPro database system encrypts the technique

基于Visual FoxPro数据库中出现的安全性问题,对于Visual Foxpro开发的软件的底层数据源表分别从外存储器和内存储器进行加密以确保数据本身的安全性,在用户使用权限上先对单机的用户密码运用加密的转换密钥和随机伪码进行加密,在分布式应用系统中的用户权限控制采用了HWANG,CHEN与LAIH的算法。

According to the safety problem appear in the database of Visual FoxPro, keep from the outside saving machine and memory for the first floor data source watch difference of the software of the Visual Foxpro development the machine carries on encrypt to insure the data of safety, at the customer uses the legal power up first to single machine of the conversion key and random false codes that the customer password usage encrypt carry on encrypt, the customer legal power control that is in the distribute type application system adopted the calculate way of the HWANG, CHEN and LAIH.
