This paper presents a novel image security system based on the replacement of the pixel values using recursive Cellular automata (CA) substitution. The advantages of our proposed method are that it is computationally efficient and it is reasonably passing sensibility analysis tests. The proposed method is carried out by using one half of image data to encrypt the other half of the image mutually....
This Cellular Automata (CA) has been used in cryptography over the past decade for its advantages in generating pseudo-random sequence. In this paper, a novel encryption algorithm for image in our project is proposed, which is based on an improved two-dimensional CA approach. A weighted and p-interval two-dimensional CA approach forms a new evolutionary matrix including lots of optional parameters...
In this paper a new image encryption system based on replacement of pixels values by using Indefinite Cellular Automata and chaos mapping is proposed. Cellular Automata rules are defined based on chaos mapping and stored in private key. Proposed system have some advantages such as confusion, diffusion, symmetric private key, very large number of secret keys, key-dependent pixel value replacement and...
