摘要： 为解决现有软件防盗版方法易于破解和使用不便的问题，设计实现一种基于USB加密锁的软件防盗版新方法。该方法先在USB加密锁内写入一个用户密钥，在软件第一次启用时将USB加密锁内的唯一性密钥和用户密钥同时写入计算机注册表中，在软件运行过程中定时比对USB加密锁和计算机注册表中2个密钥的一致性，由此判断用户的合法性。将该方法用于某商业软件，结果证明其可以有效防止盗版行为。

Abstract: To solve the problems of easy to declassification and inconvenient to use in present software piracy—proof methods, this paper designs and implements a new pirate—proof method based on USB encryption lock. A user key is written into USB encryption lock, and when the software is the first time enabled, the unique key and the user key in the USB encryption lock are written into registration table. By comparing the two keys in the USB encryption lock and registration table, the user's legitimacy is determined. The method is applied in a commercial software, and the result proves it is effective.
