摘　　要： 计算复杂性的数论密码安全性越高则加解密速度越慢。混沌密码体制的安全性基于内秉随机性,理论依据:周期3蕴含混沌。本文基于摩尔斯电码,主要提出二进制数谱替换表,构建混沌映射的虫口模型,呈现出输入信号与类元素集合之间1对多向前随机性的混沌加密特性,输出信号与单元素集合之间1对1向后确定性的单向解密特性。这种非线性双射模型在密码数学领域是首次提出的,核心贡献在于类元素集合的发现,其安全性和加解密效率会比基于计算复杂性的数论密码略占优势,适用于网络通信的大数据快速加解密。 Starting from the security of Chaotic Cryptosystem Based on intrinsic randomness Theory： period 3 implies chaos, this paper mainly presents the Morse code binary number spectrum substitution table based on constructing chaotic mapping population model shows the input signal and the elements set between 1 to forward random chaos encryption features, set the output signal and the single element between 1 to 1 backward one-way deterministic decryption. This nonlinear bijective model is first proposed in the password field of mathematics. The most important contribution of this set of elements is its security and encryption efficiency are better than the complexity of number theory cryptography based on a slight advantage, and this application is suitable for big data of network communication and decryption.
