摘要：
In this paper, a two-wing chaotic system is transformed into a four-wing chaotic system and an eight-wing chaotic system using fractal processing and the dynamic characteristics of new multi-wing chaotic systems are analyzed. The encryption of the image is accomplished by combining the eight-wing chaotic system and the improved AES algorithm. The number of AES encryption rounds is reduced to make it more suitable for image encryption. To further improve the encryption efficiency, the chaotic system circuit and AES parallel computation are designed and implemented on FPGA. Finally, the high performance of the chaotic system is demonstrated by the satisfactory encryption effect. This methodology provides a promising direction for the study of real-time image encryption.
