The experimentation shows indeterminacy of chaos's time sequence in experiments of randomicity check. So the randomicity of chaos's time sequence must be checked before it become keying sequence.
实验表明混沌密码序列对随机性的测试的好坏存在不确定性，因此混沌序列应用到序列密码之前必须对序列进行随机性检测。
Chaos masking, chaotic parameter modulation, chaos shift keying, chaotic spread spectrum sequence are discussed in detail.
