| 摘 要： | 软件的盗版问题对软件公司而言是一个需要重点面对的问题,因为一个随意的盗版行为将会给软件公司带来严重的后果。很多＂盗版者＂只是些随意复制者,他们虽然只购买了一份授权,但认为将软件复制到多台机器是可以接受的做法。为了防止软件盗版,一个比较好的办法就是使用软件加密狗,只有在计算机上插有合法的加密狗,软件才能正常使用。通过这种做法可以避免软件被任意复制,从而保证软件厂商的合法利益。文中把加密狗与密码学相结合,使用密码学中的HMAC技术来保证软件的安全性。

| Abstract: | Software piracy is a severe problem for a software company,and optional piracy usually brings a software company serious consequence.Many pirates are simply duplicators,and they purchase only one authorization,and think acceptable the duplication of the software on many other computers.In order to avoid software piracy,soft dog is a good choice.The software could not be used unless an authorized softDog is inserted in the computer.This method could prevent random duplication of the software,so that the legal profit of software companies can be guaranteed.In combination of softDog with cryptography,a softDog is designed,and the HMAC technology is employed to ensure the security of the software. |
