We propose a new lossless digital image encryption scheme based on the permutation and substitution architecture. Initially, original image is divided into squared sub‐images and then three layers of pixels corresponding to additive primary colours (RGB) of each sub‐image are separated. Each layer of pixels of squared sub‐images are scrambled by three different ways in the permutation process whereas a simple arithmetic, mainly sorting and differencing, is performed on each layer of pixels to achieve the substitution. The results of several experiments show that the proposed image cipher provides an efficient way for image encryption with high decryption rate. |
