摘要
软件盗版和软件攻击严重影响了软件产业的正常发展。在软件水印和软件特征技术的基础上,提出一种基于静态软件水印和软件指令集的软件特征值提取方法。将软件版权所有者信息和软件反编译得出的有效软件指令集合进行摘要计算,最终求得软件的特征值。设计软件特征值在软件保护中的应用方案,软件特征值经软件开发者对称加密后,可作为软件的一部分随软件可执行程序一起打包发售,用于鉴定软件的完整性和判断软件盗版源头。该方案在软件保护领域具有实际的应用价值。
Software piracy and software attack have seriously affected the normal development of the software industry. On the basis of software watermarking and software feature technology, we proposed a software eigenvalue extraction method based on static software watermarking and software instruction set. The information of software copyright owner and the effective software instruction set obtained by software decompilation were digested and calculated, and the eigenvalues of the software were finally obtained. We designed an application scheme of software eigenvalue in software protection. The software eigenvalue which had been symmetrically encrypted by software developer could be packaged and sold together as part of software along with the executable program. It could be used to identify the integrity of the software and to judge the source of software piracy. The scheme has practical application value in the field of software protection.
