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

[0145] The present invention will be further described below in conjunction with the accompanying drawings.

[0146] refer to Figure 1 to Figure 4 , a generalized chaos synchronization method applied to a controlled T system and a Shimizu-Morioka system for secure communication, comprising the following steps:

[0147] 1) Generalized chaotic synchronization problem description

[0148] The driving system involved in the generalized chaotic synchronization technology is the Shimizu-Morioka system. This system was proposed by T.Shimizu and N.Moriok in 1980. People found that it has chaotic phenomena. This system has also been verified to be realized by circuit. Its specific form is as follows :

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 using a Shimizu-Morioka chaos system as a drive system and a single-input controlled T 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 origina...
