摘　　要：提出了一种基于三维Logistic-Sine级联映射(3D-LSCM)的图像混沌加密算法。首先,将Logistic映射的输出作为Sine映射的输入,从而构造出一种三维Logistic-Sine级联映射。其次,利用3D-LSCM设计一种图像混沌加密算法,该算法采用两轮置乱、双向扩散机制,并且将明文信息作为初始条件的一部分,可增强等价密钥破译的难度。安全性能分析和数值仿真结果证实了该算法的可行性。This paper proposes a three-dimensional Logistic-Sine cascade map( 3 D-LSCM). Firstly, a three-dimensional Logistic-Sine cascade map was constructed by using the output of the Logistic map as the input of the Sine map. Secondly, this paper designs an image encryption scheme using 3 D-LSCM, which consists of two rounds of scrambling and two-way diffusion, and introduces the plaintext as part of initial conditions of 3 D-LSCM to enchance the difficulty in deciphering equivalent keys. The feasibil-ity of the algorithm was confirmed throung security analysis and numerical simulation.
