Abstract：Aiming at the scrambling of pixel position, in order to weaken the periodicity of encrypted ciphertext, a two-direction folding diffusion chaotic system encryption method based on shuffling algorithm is proposed. The simulation results show that the algorithm can not only resist differential attack, statistical analysis, strong key sensitivity, but also effectively resist ciphertext attack. Moreover, the key space is large and the encryption effect is good.
