基于Windows的软件注册防拷贝加密技术

An Anti-copy Encryption Technology for Software Registration Based on Windows

随着互联网技术的飞速发展,软件版权保护已经成为亟待解决的问题。该文提出了基于Windows软件注册的用户唯一性身份认证的软件产权保护模式,并给出了注册数据的混沌加密与解密和注册改写与检测算法。算法通过对用户试用时间予以混沌加密后写入注册表,克服了传统方法在时间限制方面的漏洞;注册数据采用混沌置乱和密钥加密双重保护,致使用户即使在获得了混沌序列生成的方法、加密密钥和个人标识的情况下,由于不清楚各数据加密所使用的混沌初值,也不能破解各注册项。

With the fast and steady development of network and software technology,how to protect the copyright of software has become a great challenge.In this paper,we present a model used for software copyright protection based on the user＇s unique feature registration in Windows,and algorithms used for data chaos encryption,decryption,and Windows registry inspection and modification.These algorithms overcome the leaks of traditional methods in software lifetime restriction,provide registry data with double protection by chaos disarrangement and encryption with cryptographic key so that the registry items couldn＇t be decrypted even though the user know about the generation method of chaotic sequences,the encryption keys,and the personal identifier because of unknowing about the chaotic initial values.
