Chaos synchronization, in particular isochronal synchronization of two chaotic trajectories to each other, may be used to build a means of secure communication over a public channel. In this paper, we give an overview of coupling schemes of Bernoulli units deduced from chaotic laser systems, different ways to transmit information by chaos synchronization and the advantage of bidirectional over unidirectional coupling with respect to secure communication. We present the protocol for using dynamical private commutative filters for tap-proof transmission of information that maps the task of a passive attacker to the class of non-deterministic polynomial time-complete problems.
混沌同步，特别是两个混沌轨迹之间的等时同步，可以用于在公共通道上建立安全通信手段。本文综述了从混沌激光系统推导出来的伯努利单元的耦合方案，通过混沌同步传输信息的不同方式，以及双向耦合相对于单向耦合在安全通信方面的优势。我们提出了使用动态私有交换滤波器进行信息无痕迹传输的协议，该协议将被动攻击者的任务映射到非确定性多项式时间完全问题的类中。
