摘要
单向耦合映象时空混沌系统产生的密钥流 ,它的随机性好、周期长、无相关性以及速度快 .系统产生密钥流对控制密钥非常敏感 ,通过少量的控制密钥就能产生大量的能够满足实际保密通信需要的密钥流 .
One-way coupled map system are used for producing keystream. It is demonstrated that this keystream has properties as good randomness, long period, uncorrelation, and fast speed. The keystream produced by this system is very sensitive with controlling key. A large number keystreams controlled by few controlling key can be used as ideal stream cipher for secure communication.
