Recently a hybrid secure image encryption scheme based on Julia set and three-dimensional Lorenz chaotic system was suggested. The offered scheme was based on the multiplicative operation carried out by Julia set fractals and bitwise XOR which was implemented by the trajectories obtained from the Lorenz chaotic system. This paper presents the cryptanalysis of the scheme through a chosen-plaintext attack by taking three different chosen images. In this work, a practical chosen-plaintext attack is performed which reveals that the cryptosystem depending on only multiplication and bitwise XOR operation can be effortlessly attacked. The results of the analysis performed on the retrieved image reflect the effectiveness of the chosen-plaintext attack which fruitfully produces the original image.

基于Julia集分形和三维洛伦兹混沌映射的混合安全图像加密密码分析

最近提出了一种基于Julia集和三维洛伦兹混沌系统的混合安全图像加密方案。所提供的方案基于由 Julia 集合分形和按位异或执行的乘法运算,该运算是通过从洛伦兹混沌系统获得的轨迹实现的。本文通过选择三个不同的选择图像,通过选择明文攻击介绍了该方案的密码分析。在这项工作中,执行了一个实际的选择明文攻击,它表明可以毫不费力地攻击仅依赖于乘法和按位异或运算的密码系统。对检索到的图像执行的分析结果反映了选择明文攻击的有效性,该攻击卓有成效地生成了原始图像。
