A Novel Image Encryption Model Based on Hybridization of Genetic Algorithm, Chaos Theory and Lattice Map
Encryption is an important issue in information security which is usually provided using a reversible mathematical model. Digital image as a most frequently used digital product needs special encryption algorithms. This paper presents a new encryption algorithm high security for digital gray images using genetic algorithm and Lattice Map function. At the first the initial value of Logistic Map ...
متن کاملColor Image Encryption by Cellular Automata
This paper presents a proposed cryptosystem to encrypt color images using cellular automata. A reversible cellular automaton has the characteristic of being able to return in the evolution of the automata, and is therefore, that in this paper are used to generate a symmetric key used to encrypt images.
متن کاملImage Steganography Based on Cellular Automata
In this paper, a new approach of image steganography using twodimensional Cellular Automata (2D-CA) has been proposed for a confidential message. We convert the message in such a way that message length becomes 1024 bits after padding some bits. If message size is more than 1024 bits, we subdivide the message of length 1024 bits using padding technique. Convert original message by XORing with s...
متن کاملA Symmetric Chaos-Based Image Cipher with an Improved Bit-Level Permutation Strategy
Very recently, several chaos-based image ciphers using a bit-level permutation have been suggested and shown promising results. Due to the diffusion effect introduced in the permutation stage, the workload of the time-consuming diffusion stage is reduced, and hence the performance of the cryptosystem is improved. In this paper, a symmetric chaosbased image cipher with a 3D cat map-based spatial...
متن کاملImage Encryption Using Chaos and Block Cipher
In this paper, a novel image encryption scheme is proposed based on combination of pixel shuffling and new modified version of simplified AES. Chaotic baker’s map is used for shuffling and improving S-AES efficiency through S-box design. Chaos is used to expand diffusion and confusion in the image. Due to sensitivity to initial conditions, chaotic baker’s map has a good potential for designing ...
