Analysis of Lorenz-chaos and exclusive-OR based image encryption scheme
In this paper, analysis of Lorenz-chaos and exclusive-OR based image encryption scheme has been presented. The Lorenz system is used in shuffling the positions of image pixels in the spatial-domain and gray values of pixels are altered with exclusive-OR operation. The encryption scheme has been validated for grayscale images using MATLAB 7.14 and is sensitive to the encryption parameters of the Lorenz system. The experimental results establish that the key-space is large enough to resist brute-force attack, and demonstrate the scheme's resistance to noise and occlusion attacks. Statistical and correlation analysis of adjacent pixels are also performed.
