Comments on “An Image Encryption Scheme Based on Rotation Matrix Bit-Level Permutation and Block Diffusion”

چکیده
Recently, an image encryption scheme based on rotation matrix bit-level permutation and block diffusion was proposed [Y Zhang, D Xiao. Commun Nonlinear Sci Numer Simulat. 2014, 19:74-82]. In this paper, this image encryption scheme was studied in detail and its defects of low encryption speed and weak security were pointed out. This scheme with one round was crypt-analyzed successfully with the chosen plaintext method. The simulation results show that their scheme cannot be used in practical communications.

A Plain- Image Dependent Image Encryption Scheme Using Half-pixel-level Interchange Permutation Operation
In this paper, a chaos-based image encryption scheme with half-pixel-level interchange permutation strategy and plain-image dependence is proposed. The proposed image encryption scheme consists of a confusion process and a diffusion process. In the confusion process, a pixel-swapping operation between higher bit planes and lower bit planes is employed to replace the traditional confusion operat...
متن کاملA New Approach for Image Encryption Based on Cyclic Rotations and Multiple Blockwise Diffusions Using Pomeau-Manneville and Sin Maps
In this paper an efficient image encryption scheme based on cyclic rotations and multiple blockwise diffusions with two chaotic maps is proposed. A Sin map is used to generate round keys for the encryption/decryption process. A PomeauManneville map is used to generate chaotic values for permutation, pixel value rotation and diffusion operations. The encryption scheme is composed of three stages...
متن کاملA New One round Image Encryption Algorithm Based on Multiple Chaotic Systems
This paper presents a bit level pixel by pixel chaotic image encryption scheme with a permutation–diffusion structure. In this scheme, a Neural Network Like Structure (NNLS) is proposed to do the diffusion efficiently. The plain image, split into 16 blocks is permuted by the keys from the key generator. Each key will produce different permutation order (PO) generated using a chaotic map. After ...
متن کاملA Chaos-based Pseudorandom Permutation and Bilateral Diffusion Scheme for Image Encryption
A great many chaos-based image encryption schemes have been proposed in the past decades. Most of them use the permutation-diffusion architecture in pixel level, which has been proved insecure enough as they are not dependent on plain-images and so cannot resist chosen/known plain-image attack usually. In this paper, we propose a novel image encryption scheme comprising of one permutation proce...
متن کاملChosen-plaintext attack of an image encryption scheme based on modified permutation-diffusion structure
Since the first appearance in Fridrich’s design, the usage of permutation-diffusion structure for designing digital image cryptosystem has been receiving increasing research attention in the field of chaos-based cryptography. Recently, a novel chaotic Image Cipher using one round Modified Permutation-Diffusion pattern (ICMPD) was proposed. Unlike traditional permutation-diffusion structure, the...
