| 摘 要： | 利用混沌系统广义同步定理，基于蔡电路系统构造了一个新的混沌系统，基于该系统设计了一个文本复合加密隐藏方案。该方案首先用复合系统产生的混沌码对明文加密，然后将密文隐藏到语音信号中。方案能够实现无失真解密。数值模拟显示新加密方案产生的混沌流具有良好的伪随机性。该方案对混沌系统的参数及初始条件极为敏感，表明该方案具有较高的安全性。数值模拟显示该方案能够有效地应用于网络通讯。

| Abstract: | A new chaos system is established based on the theorem of generalized synchronization and Chua system.The chaos sequences generated via this system and Lorenz system has better pseudo-random properties.A message encryption and hiding scheme is also established on the system and Lorenz system.The scheme is successful to encrypt and decrypt message.Ciphertexts are sensitive to the parameters and initial conditions of the chaos system.It shows that this scheme has good security.Numerical simulations show that our scheme is effective to be used in network communication. |
