Chaotic Running Key Generator Based on One-Dimensional Piecewise Nonlinear Markov Maps
【摘要】 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。
【Abstract】 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.
