无线环境下基于ARM系统的混沌同步实现及分析

摘要

Secrecy communication plays a vital role in modern science and technology field; the chaos synchronization circuit is one of the modes to achieve secrecy communication. Under wireless environment, by adopting the chaos synchronization platform based on ARM, to make the digital driving circuit generate Lorenz chaos signal that can be synchronized with the signal received by response system, thus the goal of secrecy communication is reached. The results of experiments show that if appropriately select communication parameters and control parameters, the chaos systems having the same structure and same parameter while different initial state can be synchronized on this platform. Because logical circuit possesses great advantages than analog circuit in accuracy and controllability, the chaos synchronization sequence produced using ARM has wide applicable prospects.%保密通信在现代化科技中扮演至关重要的角色，混沌同步电路是实现保密通信的一种方式。在无线环境下采用基于ARM的混沌同步平台，使数字驱动电路产生与响应系统接收信号同步的Lorenz混沌信号，从而达到保密通信的作用。实验表明，在通信参数与控制参数选择合适的情况下，同结构、同参数、不同初始状态下的混沌系统可以在此平台上达到同步。由于逻辑电路在精度和可控度方面相比于模拟电路具有巨大优势，因此基于ARM的混沌同步序列有广泛的应用前景。
