共享软件的序列号保护方式研究

Research on Serial Number Protection Approach of Shareware

序列号保护方式是目前共享软件普遍采用的反盗版措施。本文首先剖析了破解序列号保 护的技术和方法,然后将序列号保护方式所面临的安全性问题归纳为对象安全性问题、入口安全 性问题和序列号散布问题进行研究。在对每一类问题进行分析以后,本文给出了一种安全性比较 高的序列号保护方案,并进行了安全性能分析。

Serial Number Protection Approach is widely used by sharewares to protect copyright. This paper firstly analyses the techniques and methods for cracking sharewares protected by serial number, then reduces all the security problems that serial number protection approach facing to three categories： object security problem, entrance security problem and distributing serial number problem. After analyzing each kind of problem, this paper gives a solution with high security, and analyses its security performance.
