VFP软件开发安全性问题的解决方案

Solutions to the Safety Problems of VFP Software Development

基于Visual FoxPro软件开发中出现的安全性问题,对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,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,确保数据本身的安全性。

Based on the safety problems existing in Visual Foxpro software development, the data source in its first floor is encrypted from the outer and inner memory. In order to ensure the safety of the data, the customer＇s password in the single computer within the customer＇s power of use is encrypted by using the encrypted conversion key and random false code. Meanwhile, the customer＇s right of use in the distributive-type application system is controlled by adopting the algorithm of HWANG, CHEN and LATH. This article comes up with some solutions to the safety problems of visual Foxpro software development.
