摘　　要：为了实现软件加密,首先描述了利用计算机指纹信息(硬盘序列号和网卡物理地址)进行软件加密的原理;其次论述了VB、VC++和Power Builder三种编程语言实现获取硬盘序列号和网卡物理地址的原理与方法,并给出了获取计算机指纹信息的VC++源程序。最后综合利用硬盘序列号和网卡物理地址作为明文,设计了一种新的软件加密的算法,并概述了软件保护过程。实际应用证明该加密方法安全可靠。To realize software encryption, firstly, the principle and method of encoding software with the computer fingerprint（the computer driver＇s serial number and NIC＇s MAC address） were presented . The methods to obtain the computer driver＇s serial number and NIC＇s MAC address with three computer languages of VB,VC＋＋ and Power Builder are discussed ,and the VC＋＋ program codes are given for getting the computer fingerprint. A new method of encrypting software is designed synthetically by using the plain text composed of the computer driver＇s serial number and NIC＇s MAC address and summarizes the process of software protection. The encryption method testified in practical applicatiow is safety and reliable.
