Problems solved by technology

It is relatively easy to observe the phenomenon of torus generation in the second-order non-autonomous system driven by an out-of-period signal, but for the problem of torus generation in the third-order autonomous system, there are few relevant domestic and foreign literature reports, such as Nishiuchi et al. Carry out relevant research on this problem, and give the circuit experiment results of single torus and double torus (Y.Nishiuchi, T.Ueta andH.Kawakami.Stable torus and its bifurcation phenomenon in a simplethree-dimensional autonomous circuit.Chaos Solitons & Fractals, 2006, 27(4): 941-951.), but did not involve the use of four step wave sequences in the fourth-order system to generate multi-directional distributed grid-like multi-annular chaotic signals, therefore, for chaotic Confidential communication still has limitations

Abstract

The invention is related to chaos circuit needed by secret communication. The invention includes basic quadravalent cancellate chaos circuit in multiple tori, step wave sequence generation circuits in x, y, z directions, and switch bank. The method includes steps: disconnecting K1, K2, K3 generates single directional chaos attractors in multiple tori; through switching K10-K15 controls quantity of control tori; connecting K1, and disconnecting K2, K3 generate 2D distributed cancellate chaos attractors in multiple tori; through switching K10-K15, K22 controls quantity of chaos attractors in multiple tori; connecting K1, K2, K3 generate 4D distributed cancellate chaos attractors in multiple tori.

Description

technical field [0001] The invention relates to a chaotic circuit required in chaotic secure communication, in particular to a circuit which uses four step wave sequences in a fourth-order system to generate multi-directional distributed grid-shaped multi-annular chaotic signals. The invention also relates to a method for using the fourth-order mesh multi-annulus chaotic circuit. Background technique [0002] How to generate various chaotic circuits for chaotic secure communication is a new field of nonlinear circuit and system research in recent years, and some relevant research results have been obtained so far. It is relatively easy to observe the phenomenon of torus generation in the second-order non-autonomous system driven by an out-of-period signal, but for the problem of torus generation in the third-order autonomous system, there are few relevant domestic and foreign literature reports, such as Nishiuchi et al. Carry out relevant research on this problem, and give ...
