Image encryption algorithm based on double chaos map

This paper proposes a kind of image encryption algorithm based on the Logistic chaos mapping and the Henon chaos mapping. It uses Logistic chaotic dynamical system to generate a sequence of chaos, and through the algorithm of dynamic quantification in order to enhance the randomness and complexity of the sequences, disorder the original image with the new pixel address codes which are produced by the sequences and gain disordered image. Then the matrixes of the disordered image XOR with the matrixes which are generated by quantitative transformation of the sequences of the Henon mapping domain to complete the encryption of image. The simulation experimental results show that the method has a good effect of encryption and strong safe function.
