Running windows parallels encryption keygen#![]() Differential attack is commonly used in cryptanalysis, which compares the corresponding encrypted outputs of two similar plaintexts with small changes in one of them (even only one bit). This is despite the fact that an efficient image encryption must be able to resist any types of attacks. The above mentioned methods achieved satisfying results in image encryption yet have certain security drawbacks. proposed a novel image encryption scheme based on a linear hyperbolic chaotic system of partial differential equations. Furthermore, two image encryption methods were proposed in and based on 2D generalized Arnold map and 3D Arnold cat map, respectively. ![]() Zhang and Xiao proposed an image encryption scheme based on rotation matrix bit-level permutation and block diffusion. An image encryption based on DNA addition and complement operation combined with 1D and 2D logistic maps was proposed in. proposed a method for encrypting images using a new nonlinear chaotic algorithm (NCA) based on the logistic map in CML. In some image encryption schemes, coupled map lattices (CML) were employed as the model of spatiotemporal chaotic systems,. proposed a fast chaotic block cipher for image encryption based on sorting the solutions of Linear Diophantine Equation (LDE), whose coefficients are integers dynamically generated from all types of chaotic systems. designed a method for image encryption with PWLCM and Chebyshev map in the confusion and diffusion stages, respectively. proposed a novel scheme for image encryption based on 2D piecewise nonlinear chaotic map with two similar stages for diffusion. Certain researchers have designed image encryption algorithms based on piecewise nonlinear chaotic maps (PWNLCM), , : Akhshani et al. ![]() proposed an image encryption algorithm based on Chua chaotic system with pixel and bit shuffling. Parallel sub-image encryption with hyper chaos and time-delaying image encryption scheme based on hyper chaotic map were proposed in and, respectively. proposed an image encryption algorithm based on hyper-chaotic system with only one round of diffusion process. Two image encryption algorithms were designed based on DNA sequence and hyper-chaotic system in and. proposed a symmetric image encryption scheme with PWLCM for creating permutation matrices in the confusion stage and Chen's chaotic system in the diffusion stage. Some researchers employ hyper chaotic systems, ,, ,. There exist a large number of image encryption methods owing to the variety of chaotic maps.Ī novel algorithm was proposed in for image encryption based on the mixture of chaotic maps. Chaotic system is a deterministic nonlinear system possessing various characteristics, such as high sensitivity to initial conditions, and determinacy and has recently attracted many researchers into using it for image encryption. Image encryption is one of the most effective ways of guaranteeing the transmission security of digital images that are being widely transmitted in the public communication networks.
