Abstract

The invention provides an implementation method of a novel chaotic oscillation circuit. According to the implementation method, a first integrator of an integrated operational amplifier U1 is used forrealizing operation of a first equation of a chaotic system; the operation of a second equation of the chaotic system is realized through a first adder and a second integrator of the integrated operational amplifier U1, a second reverse integrator of an integrated operational amplifier U2, and a first multiplier U3; and the operation of a third equation of the chaotic system is realized through asecond adder, a third integrator, a third inverter, a second multiplier U4, a third multiplier U5 and a fourth multiplier U6 of the integrated operational amplifier U2. A hidden attractor exists in the oscillation circuit, and meanwhile a coexistent attractor exists, so that a generated sequence has higher security, higher performance, and a very high reference value and a very good application prospect in the fields of chaotic signal generation, secure communication, character image encryption and the like.

Description

technical field [0001] The invention belongs to the technical field of information security and relates to a method for realizing a novel chaotic circuit, in particular to a method and method for realizing a chaotic oscillation circuit without an equilibrium point with a hidden attractor, which is used to generate a chaotic pseudo-random sequence with good performance. Background technique [0002] Chaotic signals have continuous wide-spectrum random characteristics, and can be used to generate a new generation of pseudo-random sequences with good performance, which can be used in secure communication and information encryption. The chaotic signal required for chaotic secure communication or information encryption is generated by the chaotic oscillator circuit, and its security depends on the complexity of the chaotic signal. Existing chaotic oscillation circuits are based on chaotic systems with equilibrium points, such as Lorenz systems, system, Chen system, Lü system an...
