摘要
从混沌动力学的角度出发,运用非线形控制系统的原理来研究混沌序列.以Henon映射为基础,在控制系统设置控制参数以形成混沌序列.同时也证明了模加减运算是成立的,并给出了相应定理的证明.在图像加密新算法中,运用了异或运算和模加减运算相结合的方式.实验结果证明,该算法生成的混沌序列对图像加密具有比较好的效果.
Using non-linear control system knowledge, the chaotic sequence from the perspective of chaotic dynamics was studied. This article is based on Henon mapping, using the principle of control system, setting up parameters and forming a chaotic sequence. This paper proves the the addition and subtraction algorithm of model is correct with two theorems provided. This article use a method combining XOR and addition and subtraction algorithm of model A post-mortem result shows relatively good results in image eneryption.
