Design of a Stream Cipher Algorithm Based on Latin Square and Time-Varying Symbolic Chaotic System
摘要: 本文研究了一类三维时变广义符号动力系统的混沌性，并对它的多种伪随机性能进行了分析。在此基础上，结合拉丁方构造的基本密码系统，设计了一种多元流密码算法。最后，对该算法在数字图像上的加密效果进行了仿真，并与模2加法流密码系统的仿真结果进行了对比。仿真结果分析表明新流密码算法具有良好的加密效果和较高的安全性。
Abstract: This paper studies chaos of a class of three-dimensional time-varying generalized symbolic systems, and analyzes the pseudo-randomicity of its solutions. Then, combined with the basic cryptosystem designed by Latin square, a stream cipher algorithm was designed. Finally, the encryption effect of the algorithm on digital image is simulated and compared with the simulation results of the modulo 2 addition stream cipher system. Simulation shows that this algorithm has good encryption effects.
