摘　　要：为了提高软件水印的抗攻击性能,文章提出了基于中国剩余定理和混沌序列的软件水印分割和散列方案。运用中国剩余定理将水印信息进行分割,设计改进的Logistic映射将水印信息映射成混沌序列生成子水印,最后利用混沌序列将子水印散列到宿主程序中。由于混沌序列具有初始值敏感特性、类随机性和不可预测性,该方案能明显提高软件水印的鲁棒性和隐蔽性。In order to improve the anti-attack performance of the software watermarking, a software watermarking split and dispersion scheme based on Chinese remainder theorem and chaotic sequence is developed. The copyright is split by using Chinese remainder theorem, and an improved Logistic map is designed to generate chaotic sequence, in which the sub-watermarking is inserted into the host pro- gram. Then the sub-watermarking is dispersed into the host program. In view of the properties of chaotic sequence such as initial value sensitivity, random-like property and unpredictability, the proposed scheme greatly improves the robustness and imperceptibility of the software watermarking.
