中文摘要：

在这篇论文，基于一个适应混乱同步计划，译电文为密码译码的二个方法发送消息因为安全通讯被建议。与第一个方法，消息直接与参数不确定性被加到混乱信号。在第二个方法，多参数调整被用来同时播送超过一条数字消息(即，多信道的数字通讯) 通过就一个单身者发信号，它在仅仅微妙地不同的各种各样的混乱引起注意的人之中切换。在理论，如此的一个处理增加困难让入侵者直接拦截信息，并且同时，实现费用显著地减少。另外，数字结果证明方法对弱噪音是柔韧的，它暗示他们的有实行可能。

英文摘要：

In this paper, based on an adaptive chaos synchronization scheme, two methods of encoding-decoding message for secure communication are proposed. With the first method, message is directly added to the chaotic signal with parameter uncertainty. In the second method, multi-parameter modulation is used to simultaneously transmit more than one digital message （i.e., the multichannel digital communication） through just a single signal, which switches among various chaotic attractors that differ only subtly. In theory, such a treatment increases the difficulty for the intruder to directly intercept the information, and meanwhile the implementation cost decreases significantly. In addition, numerical results show the methods are robust against weak noise, which implies their practicability.
