A novel hybrid permutation substitution-based color image encryption scheme is presented. The permutation is desirable property to have which make any security system diffusing. In present article, permutation is applied through p-box. The substitution process is also vital because it create confusion. In presented work substitution is applied through S-p-box. 3D mixed chaotic map is utilized to make our algorithm more diffusing and confusing. The permutation box, permutation substitution box and initial conditions of 3D mixed chaotic map are also utilized as a key. The experimental outcomes of proposed technique have been critically analyzed and a comprehensive comparison with existing schemes is presented.

一种新颖的基于混合置换替换的多媒体数据彩色图像加密方案

提出了一种新颖的基于混合置换的彩色图像加密方案。排列是使任何安全系统扩散的理想属性。在本文中,置换是通过p-box应用的。替代过程也很重要,因为它会造成混乱。在提出的作品中,通过Sp-box进行替代。利用3D混合混沌图使我们的算法更加分散和混乱。3D混合混沌映射的置换框,置换置换框和初始条件也被用作关键。已对所提出技术的实验结果进行了严格分析,并与现有方案进行了全面比较。
