In the recent decade, chaos-based image encryption algorithms gained attention due to their pros and cons. The authors suggest one such algorithm of image encryption for different colour space using feed forward initial condition to pursue random permutation by combining 1D logistic map with a series of tent maps. The algorithm adds one more novel step to protect and encrypt binary image by concealing it within a cover grey image using bit-plane decomposition methods. Sensitivity towards initial condition is shown using block division of image by applying a stream of random initial conditions to each block for encryption along with XOR operation which leads the key space high . For better performance analysis, the proposed scheme has been tested with many colour space images including a binary image. The proposed technique is more efficient with respect to time complexity and resistance to vulnerability aspects.

可感知的可访问图像加密方案，共轭多个混沌图

在最近的十年中，基于混沌的图像加密算法因其优缺点而受到关注。作者提出了一种这样的图像加密算法，该算法使用前馈初始条件通过将一维逻辑图和一系列帐篷图结合起来，使用前馈初始条件进行随机排列。该算法通过使用位平面分解方法将二进制图像隐藏在覆盖的灰度图像中，从而增加了一个保护和加密二进制图像的新步骤。通过对每个块应用随机初始条件流以进行加密以及XOR操作（导致密钥空间变高），使用图像的块划分来显示对初始条件的敏感性 。为了进行更好的性能分析，已针对包括二进制图像在内的许多色彩空间图像对提出的方案进行了测试。所提出的技术在时间复杂度和对脆弱性的抵抗方面更有效。
