The Production Algorithm of Pseudo-Random Number Generator Based on Compound Non-Linear Chaos System

Pseudo-random number generator designs based on the traditional characteristic polynomial and the register slow in speed, and short life cycle. This paper a compound chaos system is designed using the nonlinear Logistic mapping system and the partition mapping. A production algorithm of pseudo-random number generator based on the compound non-linear chaos system is introduced. Theoretical and experimental results show that the random sequences produced by this pseudo-random number generator has good cryptology performance, making the design an ideal pseudo-random number generator. A new chaos stream cipher encryption system is designed based on the algorithm. Experimental results show that this stream cipher is desirable in terms of security, costeffectiveness and pseudo-randomness .
