【摘要】 根据混沌系统无振荡同步提出一种基于混沌无振荡同步的保密系统。这种混沌系统具有快速同步性，设计时可以控制其同步时间。在加密/解密过程中，加密/解密系统一旦发生干扰，可以在设计的同步时间内达到同步。此外，该文的加密方案中传输信号不仅包括加密信号，还包括同步信号，这就避免相空间重构攻击。由于这种保密通信系统采用离散恒定系统，所以可和传统的数字加密方法进行组合，产生一种新的密码组合结构。更多还原

【Abstract】 In this paper, a new chaotic cryptosystem based on chaotic dead-beat synchronization is proposed. The ability of synchronization is so good that it can be controlled in the design period. If the encrypter or the decrypter is disturbed, it will reach synchronization in the designed steps. Furthermore, the transmitted signal includs the synchronization signal and the encrypted signal. So it can avoid the reconstruction. This method is based on discrete-time systems, so it can be combined with traditional encryption method.更多还原
