Cryptanalysis of an Image Encryption Algorithm Based on Random Walk and Hyperchaotic Systems
Recently, an image encryption algorithm based on random walk and hyperchaotic systems has been proposed. The main idea of the original paper is to scramble the plain image by means of random walk matrix and then to append diffusion. In this paper, the encryption method with security holes is analyze...
