Problems solved by technology

Chaotic modulation is a way to solve complex problems in secret communication proposed by Halle and Hasler in 1992. The basic idea is to modulate the original signal with a chaotic signal and send it together; while the receiver demodulates and separates the the original signal; the third party cannot decrypt it because it does not know the dynamic characteristics of the chaotic signal

Embodiment Construction

[0116] The present invention will be further described below in conjunction with the accompanying drawings.

[0117] refer to Figure 1 to Figure 4 A generalized synchronization method between a controlled Finance system and a Genesio-Tesi system applied to secure communication, comprising the following steps:

[0118] 1) Generalized chaotic synchronization problem description

[0119] The driving system involved in the generalized chaotic synchronization technology is the Genesio-Tesi system, which was first proposed in 1992 (Genesio R, Tesi A. Harmonic balance methods for the analysis of chaotic dynamics in nonlinear systems. Automatica 1992,28:531–548. ), it is found that it has a chaotic phenomenon, and this system has also been verified that it can be implemented in a circuit, and its specific form is as follows:

Abstract

A Generalized synchronization method for controlled Finance system and Genesio-Tesi system applied to secure communication comprises that follow steps: 1) describing of a generalized chaotic synchronization problem; 2) state transformation and feedback of the response system; 3) state transition of driving system; 4) Generalized synchronization. The invention provides the Generalized synchronization method for controlled Finance system and Genesio-Tesi system applied to secure communication, The Genesio-Tesi system is the driving system, and the controlled Finance system with single input isthe responding system. A chaotic synchronization algorithm is designed by using the method of state space transformation, which realizes the generalized synchronization and has high control quality.

Description

technical field [0001] The invention belongs to the technical field of chaos synchronization applicable to secure communication, and in particular relates to a chaos synchronization method which uses a Genesio-Tesi chaos system as a drive system and a single-input controlled Finance system as a response system. Background technique [0002] Chaotic motion is a branch of nonlinear disciplines, but its scope has greatly exceeded the boundaries of traditional nonlinear disciplines, and has developed into a comprehensive, cross-cutting, cross-disciplinary branch of disciplines, which greatly broadens people's understanding of nonlinear disciplines. The horizon of science has a deeper understanding of nonlinear science. [0003] Chaos has also been applied to laser secure communication. A typical application is chaotic modulation. Chaotic modulation is a way to solve complex problems in secret communication proposed by Halle and Hasler in 1992. The basic idea is to modulate the...
