Research on Pseudorandom Number Generator Based on Several New Types of Piecewise Chaotic Maps

This paper proposes three types of one-dimensional piecewise chaotic maps and two symmetrical presents five theorems. Furthermore, some examples that satisfy the theorems are constructed, an analysis model dynamic properties discussed. The construction methods proposed in this have a certain generality provide theoretical basis for constructing new discrete system. In addition, designs pseudorandom number generator based on map studies its application cryptography. Performance evaluation shows can generate high quality random sequences efficiently.
