| Abstract： | Because of the difficulties in image encryption and information leakage, through the process of theoretical calculation and simulation, an image encryption method of a four-dimensional six-wing chaotic system combined with the DNA algorithm is proposed. The system has rich dynamic characteristics, and the key parameters such as: Lyapunov index, bifurcation diagram, power spectrum diagram, and stability of equilibrium point are calculated and analyzed. Secondly, a simulation test circuit is established, and the simulation results are implemented by using Multisim14 software, in which the proposed chaotic system circuit has good chaotic dynamics capability, and the circuit is simple and practical. In addition, three aspects, including information entropy, gray histogram, and correlation of adjacent pixels, are calculated to analyze the function of this method in image encryption, and the results show that it has high security performance. |
