基于一维分段非线性Markov映射的混沌滚动密钥产生器

Chaotic Running Key Generator Based on One-Dimensional Piecewise Nonlinear Markov Maps

用拓扑共轭映射对一维分段线性映射进行非线性化处理,所构成的复合迭代混沌系统及其不变分布具有偶对称特性,最终生成的二值混沌序列具有理想的密码学特性。

One nonlinearization method utiliz ing topological conjugate maps is pr oposed in this pa-per.The compound maps after the tran sformation are even maps and have even -symmetric invariant distribu-tion,and the generated sequences have ideal cryptographic properties.
