基于时空混沌的伪随机序列发生器设计与分析
Design and analysis of pseudo-random sequence generator based on spatiotemporal chaos
摘要
Abstract
An improved spatiotemporal chaotic model based on coupled tent map lattices is proposed, and a new pseudo-random sequence generator is designed based on this model, which can generate quickly multidimensional and chaotic pseudorandom sequence. The model inherits the parallel iteration mechanism and coupled diffusion in space and time of the coupled tent map lattices system, and use cat map as the coupling method between lattices so as to make the mutual infor-mation between different lattices approach zero. The pseudorandom sequence generator based on this model can generate multiple-output multidimensional chaotic pseudorandom sequence, which has the features of uniform distribution and inde-pendence of each other, to overcome the fundamental flaws existing in designing of chaotic pseudo-random sequence generator.关键词
