Abstract

In order to extend the security of image encryption algorithm, an extended digital image encryption algorithm based on chaotic sequence and iteration is presented in this paper. An extended real chaotic magic square matrix is also presented in this paper, the matrix is used to permute and substitute the image's pixels. The simulation results show that the effect of encrypted image and decrypted is good, the security of the extended algorithm is also ameliorated.
