Abstract :
Traditional permutation encryption algorithm is not robustness for noise disturbing and shear transformation attacks. In order to ameliorate the security of image encryption algorithm, we present an image encryption algorithm based on location transformation. The algorithm permute image based on chaotic system and storage everyone pixel of the image in multi-place, this encrypted image is robustness for noise disturbing and shear transformation attack. An extended magic square matrix-generating algorithm is also presented and it improves on the efficiency of the magic square matrix-generating algorithm. The simulation results show that the effect of decrypting image is good when the encrypting image is modified by noise disturbing and shear transformation attack
