Problems solved by technology

[0002] There are many reports in the literature on the method of using analog circuits to realize chaotic systems, and there are also reports on the use of digital circuits (such as FPGA) to realize automatic switching of chaotic systems, but the method of using analog circuits to realize automatic switching of chaotic systems has not been reported. Circuits can prove the existence of chaotic systems more effectively than digital circuits. Therefore, it is particularly necessary to design a method for automatically switching chaotic systems using analog circuits.

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] see Figure 1-Figure 8 , first construct an automatic switching chaotic system, a chaotic system (a) selected in this preferred embodiment is:

[0033] (a) a=8,b=40,d=0.7,c=10 / 3,g=4

[0034] Another chaotic system (b) selected is:

[0035] (b) a=8,b=40,d=0.7,c=10 / 3,g=4

[0036] Under the same parameter conditions as (a), the Lyapunov exponent of system (b) is: LE 1 =0.529 LE 2 =0 LE 3 =-12.577; The fractal dimension D of the chaotic attractor 2 =2.0422, at this time the chaotic system (b) is also in a chaotic state.

[0037] Construct a choice function system (c) combining chaotic systems (a) and (b) into a new switching chaotic system (d):

[0038] (c)

[0039] (d)

[0040] Under the same parameter conditions as systems (a) and (b), the Lyapunov exponent of...

Abstract

The invention discloses a method for implementing an automatically switched chaotic system by using an analogue circuit, which comprises: forming an automatic switching system by combining two chaotic systems; and using the analogue circuit to implement the automatically switched chaotic system. In the invention, the automatic switching between the two chaotic systems is realized by the analogue circuit, so the existence of the switching of the chaotic systems is proved effectively; when the switching system is used for chaotic synchronization-based secure communication, the security of the chaotic synchronization-based secure communication is enhanced; when the switching system is used for keying technology-based chaotic communication, the inter-system switching is more flexible and convenient; therefore, the automatically switched chaotic system has a promising application prospect.
