The Logistic-Sine map (LSM) chaotic system is introduced by combing the Logistic map (LM) and Sin map (SM). The bifurcation diagrams show that the chaotic range of LSM is much larger than these of the Logistic or Tent maps. Complexity characteristics of Logistic map, Sine map and Logistic-Sine map are analyzed based on C0 algorithm. The results show that C0 complexity value of the LSM is the largest one among the three. Then, a novel image encryption scheme based on the LSM chaotic system was proposed. First, the positions of image pixels are shuffled through swapping positions randomly by using chaotic values. The permutation sequences are ralated to plain-images by introducing the plaintext feedback technique. Second, the diffusion procedure with LSM is introduced to diffuse the image, which is composed of two rounds. The experimental results and analysis by using several security measures show that the proposed image encryption scheme has high security and efficiency.
