A New Efficient Approach Based On Chaotic Map For Image Encryption
Keywords:Image Encryption, Chaotic Generator, Permutation of Pixels, NPCR, UACI
The protection and security of data and information have become of paramount importance in the deferential areas including imaging, so it is best to protect them before transmitting them. Today, various types of techniques and methods based on Chaotic Encryption are used to overcome several types of threats. In this paper, we propose a new efficient image encryption system using a new simple function permutation pixels(confusion) of an image and a chaotic generator map, the proposed cryptosystem based on three steps: confusion, shuffling, diffusion. In the confusion step, the pixels of the original image is swapped by a simple permutation function. In the shuffling step, the confusing image is devised over four blocks as each block of pixels of the image is mixed, allowing to give more unpredictability. In the diffusion step, the shuffling image is diffused by combining chaotic sequence generated from the chaotic generator map used. The evaluation parameters used are: Number of Pixel Rate Changes (NPCR), Unified Average Change Intensity (UACI), Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE).
