摘要
针对彩色图像加密问题,构造了一种多涡卷混沌映射系统,提出了基于该混沌映射系统的图像加密算法,实验结果表明:该算法具有较好的密钥敏感性、很大的密钥空间和较好的扩散和混淆能力,可以有效地抵抗统计攻击和穷举攻击,具有很好的安全性。
For color image encryption, this paper constructed a multi-scroLl chaotic system and put forward the image encryption algorithm based on the chaotic system. The experimental results show that the algorithm has better key sensitivity, large key space and the ability of diffusion and confusion. The algorithm can effectively resist the statistical attack and exhaustive attack and it has good safety.
