Two-chaotic system image encryption schemes

An image encryption algorithm based on Baker map and two-chaotic system (Logistic dynamic system and Lorenz dynamic system) is presented.The algorithm splits the original image into small blocks and uses a random point as start point in baker map.The two-chaotic sequence,built with logistic system and Lorenz equation,combines with baker map to implement image encryption.This new algorithm can reduce the length of encryption sequence and enhance security of encryption.Experiments show that the algorithm is sensitive to encryption keys and can resist differential attacks.
