Abstract: In order to improve the ability of image encryption and transmission, a component fusion image encryption method based on composite chaotic model is proposed. The Logistics chaotic map is used to scramble the pixels of the clear text image, and the clear text is used to control the output of the key stream. The relation between the key stream and the plaintext is used to recognize the pixel gray level of the compo-nent fusion image, and the binary vector quantization characteristic quantity of the component fusion image coding is obtained by using the single bit detection method. The piecewise linear coding method is used to realize the arithmetic coding and cyclic encryption of the component fusion image, and the composite chaotic model is used to realize the key construction and vector quantization encryption of the image. The simulation results show that the proposed method has strong anti-attack ability and good image encryption performance, which ensures the security of image transmission and storage.
