本文利用所构造的高阶拉丁方设计了一种新的基本密码系统，并结合常用的Logistic混沌系统提出了一种新的流密码算法。而且，将这种流密码算法应用于图像加密，并对加密效果进行了仿真。仿真结果表明该算法不仅密钥敏感性强、密钥空间大，而且加密后图像具备相邻像素相关性小，信息熵大等优点。 This paper uses the constructed high-order Latin square to design a new basic cipher system, and combines the commonly used Logistic chaotic system to propose a new stream cipher algorithm. Moreover, applying this stream cipher algorithm to image encryption, the encryption effect is simulated. The simulation results show that the algorithm not only has strong key sensitivity and large key space, but also the encrypted image has the advantages of small correlation coefficient among neighbor pixels and large information entropy.
