混沌是在非线性动力系统中出现的类似随机而非随机的过程,其混沌序列在分布上不符合概率统计学原理,利用该特性,可以构建安全的加密系统。陈氏混沌吸引子拥有复杂丰富的动态特性,生成的加密信号同传统保密通信方法相比在抗破译性能方面得到较大的提高。
Chaos is a similar random but not random process in nonlinear dynamical systems. Its chaotic sequence does not accord with the principle of probability and statistics in distribution, and it can be used to construct a secure encryption system. Chan chaotic attractor has complex and rich dynamic characteristics, and the generated encrypted signal is greatly improved in anti-deciphering performance compared with the traditional secure communication method.
