摘　　要：本文首先对软件保护技术进行了简要的概述,在剖析MD5算法工作原理的基础上,提出了基于MD5加密算法的软件硬加密保护方案。该方案根据机器的CPU序列号和语音卡号使用MD5加密算法自动生成软件序列号,并对MD5加密算法的输入输出数据进行变化处理。结果显示,该方法实现了"一机一码",并已应用于某"电话语音系统"中。This paper first briefly introduced software protection technology. An approach for software protection was then proposed based on MD5 encryption algorithm with analysis of its operating principle. In this approach, a software serial number could be automatically generated by MD5 algorithm according to machine CPU serial number and speech card number, and the input and output data of MD5 encryption algorithm were processed with variability. The experiment results showed that this approach realized individual protection and it has been applied to certain telephone speech system..
