In this paper, a color image encryption algorithm based on DNA encoding combined with logistic map and spatial map is proposed. Firstly, the algorithm carries out scrambling by logistic map for R, G, B channels. Then, XOR is operated between channels pixel and sequence matrix controlled by spatial map. After that, realizes the addition of R, G, B by DNA addition after DNA encoding and carries out complement operation by using the DNA sequence matrix controlled by spatial map. What is more, R G B channel images are got after DNA decoding. Finally, gets the encrypted R, G, B images by reconstructing R, G, B components. The results of several experimental, statistical analysis and key sensitivity tests show that the proposed image encryption algorithm provides an efficient and secure way for real-time image encryption and transmission.
