摘　　要：软件加密保护是软件开发过程中的重要环节。这篇文章提出了一套基于网络的中小型工程计算软件版权保护的完整解决方案,此方案从控制软件的下载权限开始,之后在用户下载软件的同时利用DES对称加密算法加密网卡MAC地址形成了唯一的注册码,最后在软件客户端加上注册模块并通过对注册表的读写操作实现了将软件绑定在下载软件的计算机上使用的目标。此方案软件加密速度快,用户注册简单,完全不增加软件开发的成本,是一种简单实用的软件保护方案。Software encryption and protection is the important part in the course of software developing. This article brings forward a Web-based software protection scheme for the medium-sized and abbreviated engineering software. It starts with controlling the down-loading right of the software, then when the client is downloading the software, the scheme encrypts the MAC address of the network card to form the exclusive registered code of the computer by using the famous DES algorithms. At last this scheme adds a registering module to the protected software and through reading and writing the computer＇s registry the scheme can implement the software＇s protecting aim of binding the software to the computer which has downloaded the software. The encrypting and registering rate is very fast in this scheme, and the registering process is very convenient to the user and it does not increase the cost of the software exploitation at all. It is a simple and applied software protecting scheme.
