Problems solved by technology

However, many scholars have not deeply considered the impact of switching frequency on chaotic systems. If the switching frequency is a chaotic signal, the chaotic signal transmitted on the channel is more random, and it is more difficult to predict and crack

Abstract

The invention discloses a method for realizing synchronous sliding mode secret communication based on a four-dimensional automatic switching chaotic system. The method comprises the steps of establishing the four-dimensional automatic switching chaotic system, analyzing dynamic characteristics of the four-dimensional automatic switching chaotic system with a bifurcation diagram, further analyzing and calculating a balance point of the four-dimensional automatic switching chaotic system, calculating a characteristic value of the balance point and a corresponding Lyapunov index with a Jacobian matrix to judge whether the four-dimensional automatic switching chaotic system is a chaotic system and judge phase space diagrams of different switching frequencies of the chaotic system, and finally designing a synchronous sliding mode controller based on the four-dimensional automatic switching chaotic system to realize synchronization of the automatic switching chaotic system in the same structure and with transmission signal modulation. An experiment simulation result shows that the method is effective, can recover a secret signal well, and has certain robustness.

Description

technical field [0001] The invention relates to a new type of four-dimensional automatic switching system analysis and a method for realizing secure communication, and specifically belongs to the technical field of chaos synchronous secure communication. Background technique [0002] Chaotic synchronous secure communication refers to the secret transmission of information under the premise of synchronous state of chaotic system. The performance of secure communication is directly related to chaotic signal, synchronization performance, anti-jamming and so on. There are many classical chaotic systems, and both the analysis of the dynamic characteristics of chaotic systems and the research on synchronous control have been thoroughly studied by scholars at home and abroad. In particular, the research on classical chaotic systems in secure communication is also very extensive, and many scholars have proposed related deciphering methods. To improve the performance of secure comm...
