Abstract
Image encryption has an important role in life, and an more interesting research object, this paper puts forward an image encryption algorithm with run chain sequence combined with Logistic and Henon chaotic system.With the color image transformed by a discrete cosine transform (DCT) in the frequency domain, and the Henon chaotic map is combined to encrypt an image. The Logistic chaos for further encryption, with the order of different combinations of multiple encryption processing, carry out simulation experiments.The simulation results show that algorithm can achieve better encryption effect and has certain application value in the aspect of graphic information security.
