摘要: 利用离散广义混沌同步定理,基于3D-Lorenz系统构造了一个新的离散混沌系统,并结合Arnold猫映射设计了一种音频复合加密方案。该方案首先用复合系统产生的混沌码对明文进行加密,然后将密文隐藏到wav语音信号中,解密过程能够实现无失真解密。数值模拟表明,新的离散混沌系统产生的混沌流具有良好的伪随机性,并且音频隐藏方案对混沌系统的参数及初始条件极为敏感,具有较高的安全性,能够有效地应用于网络通讯。

Abstract: A new chaos system was established based on the theorem of generalized synchronization and 3D-Lorenz system.The chaos sectuences generated via this system and Arnold' s cat map have better pseudo-random properties. A message encryption and hiding scheme was also established on the system and Arnold's cat map. The scheme is successful to encrypt and decrypt message. Ciphertexts are sensitive to the parameters and initial conditions of the chaos system. Numerical simulations show that our scheme is effective to be used in network communication. It shows that this scheme has good security.
Key words: Generalized synchronization theorem, Encryption and hiding scheme, Pseudo-random properties of chaos sequence
