【摘要】 提出了一种基于混沌系统的安全通信方案。该方案将明文加密两次产生两组密文,然后一起隐藏到双声道的数字语音信号的不同声道的不同位上去。每次加密用随机的初始条件产生密钥流,使该方案具有类似一次一密的功能,方案能发现第三者对加密信息的非法篡改。数值模拟表明该方案密钥空间较大,具有较高的安全性。更多还原

【Abstract】 A new secure communication scheme using chaotic system is proposed. The system encrypts plaintext twice and encrypts the initial conditions, which then are hidden in the sound signal. The scheme has the one - time pad function. It can also discover the illegal adaptation from the third one. Numerical simulations show that the key space is secure in network communication.更多还原
