Method for realizing automatic switching of seven Lorenz type chaotic systems and analog circuit

Abstract

A method and an analog circuit for implementing automatic switching of seven Lorenz type systems for a chaotic system. The chaotic circuit for implementing automatic switching of seven Lorenz type systems is formed by an operational amplifier U1, an operational amplifier U2, an operational amplifier U3, an operational amplifier U5, an operational amplifier U8, a multiplier U4, a multiplier U9, a multiplier U10, a multiplier U11, a multiplier U12, a multiplier U13, a voltage comparator U7 and an analogue switch U6. In the present invention, by means of the analog circuit, the method and the analog circuit for implementing automatic switching of seven Lorenz type systems for the chaotic system are implemented, the seven sub-systems have different balance points, so that the automatic switching of the seven sub-systems with the different balance points is more random than that of sub-systems with same balance points, and generated digit sequences are more applicable to chaos-based secret communications and have a better application prospect in the chaos-based secret communications.

Description

technical field [0001] The invention relates to an analog circuit for realizing automatic switching of seven systems, in particular, to a method and an analog circuit for realizing the automatic switching of chaotic systems of Lorenz type seven systems. Background technique [0002] At present, there are many ways to use analog circuits to realize integer-order and fractional-order chaotic systems and circuits, but the number of subsystems that use analog circuits to automatically switch chaotic systems is relatively small, generally no more than four, and the existing automatic switching The subsystems of the chaotic system have the same balance point, and there is no disclosure of a method and an analog circuit for automatic switching of multiple sub-chaotic systems with different balance points. The automatic switching of the subsystem of the point has greater randomness, and the generated digital sequence is more suitable for the secure communication based on chaos, and ...

[0002] At present, there are many ways to use analog circuits to realize integer-order and fractional-order chaotic systems and circuits, but the number of subsystems that use analog circuits to automatically switch chaotic systems is relatively small, generally no more than four, and the existing automatic switching The subsystems of the chaotic system have the same balance point, and there is no disclosure of a method for automatic switching of multiple sub-chaotic systems with different balance points and an analog circuit. Seven subsystems in the present invention have different balance points, which is more than having the same balance point. The automatic switching of the point subsystem has greater randomness, and the generated digital sequence is more suitable for chaos-based secure communication, and has better application prospects in chaos-based secure communication
