Abstract

Purpose With the development of integrated circuit and communication technology, digital secure communication has become a research hotspot. This paper aims to design a five-dimensional fractional-order chaotic secure communication circuit with sliding mode synchronous based on microcontroller (MCU). Design/methodology/approach First, a five-dimensional fractional-order chaotic system for encryption is constructed. The approximate numerical solution of fractional-order chaotic system is calculated by Adomian decomposition method, and the phase diagram is obtained. Then, combined with the complexity and 0–1 test algorithm, the parameters of fractional-order chaotic system for encryption are selected. In addition, a sliding mode controller based on the new reaching law is constructed, and its stability is proved. The chaotic system can be synchronized in a short time by using sliding mode control synchronization. Findings The electronic circuit is implemented to verify the feasibility and effectiveness of the designed scheme. Originality/value It is feasible to realize fractional-order chaotic secure communication using MCU, and further reducing the synchronization error is the focus of future work.

基于滑模理论和单片机的分数阶混沌保密通信电路设计

目的随着集成电路和通信技术的发展，数字保密通信已成为一个研究热点。本文旨在设计一种基于单片机的五维分数阶滑模同步混沌保密通信电路。首先，构造了一个用于加密的五维分数阶混沌系统。采用Adomian分解方法计算了分数阶混沌系统的近似数值解，得到了系统的相图。然后，结合复杂度和0-1测试算法，选择分数阶混沌系统的加密参数。此外，构造了基于新趋近律的滑模控制器，并证明了其稳定性。采用滑模同步控制可以在短时间内实现混沌系统的同步。电子电路的实现验证了所设计方案的可行性和有效性。独创性/价值利用单片机实现分数阶混沌保密通信是可行的，进一步减小同步误差是今后工作的重点。
