摘要
提出一种新的混沌同步数字加密通信方案,在该方案中,首选将加密系统输出的同步信号数字化,然后将同步信号进行移位并与密匙异或作为传输信号,经公开信道传输到接收系统,接收系统反解出同步信号用于同步,当两系统同步后,将加密系统的混沌信号与信息异或进行保密通讯.数值仿真结果表明,与同类加密系统的加密方案相比,该加密方案具有密匙取值范围广,加解密速度快,抗干扰及抗破译性能好等优点.
A new chaos synchronization and digital communication is proposed.It firstly changes the synchronized signal of encryption into digital signal,then digital signal making shift and an ieor with the keys is transmitted into decryption by open channel,at last synchronizes the decryption with the extracted synchronized signal.After synchronized,one of chaotic signal from encryption making an ieor with plaintext is used in secrect communication.The simulation work indicates that the advantages of this encryption's communication are its high level of security and resistance to,large extensive key's choice,fast encryption speed compared with the same kind of encryption schems.
