“…[31] designed a new 3D chaotic system using an FPGA. Additionally, since the entire chaotic system generation process is encapsulated within the encryption unit, it is difficult for attackers to acquire the structure of the chaotic system externally, thus physically ensuring the security of the encryption algorithm [32]. Based on the above analysis, this study combined the fast computing advantages of FPGAs and designed an adaptive fast image encryption algorithm whose main contributions include: (1) proposing a novel three-dimensional chaotic system, which was found to demonstrate diverse phase trajectories, offset behaviors, and expansioncontraction phenomena in response to parameter variations, encompassing a broad chaotic range suitable for integration within image encryption; (2) implementing this chaotic system with an FPGA and designing a chaos sequence generator for image encryption;…”

This paper introduces a novel three-dimensional chaotic system that exhibits diverse dynamic behaviors as parameters vary, including phase trajectory offset behaviors and expansion–contraction phenomena. This model encompasses a broad chaotic range and proves suitable for integration within image encryption. Building upon this chaotic system, the study devised a fast image encryption algorithm with an adaptive mechanism, capable of autonomously determining optimal encryption strategies to enhance algorithm security. In pursuit of heightened encryption speed, an FPGA-based chaotic sequence generator was developed for the image encryption algorithm, leveraging the proposed chaotic system. Furthermore, a more efficient scrambling algorithm was devised. Experimental results underscore the superior performance of this algorithm in terms of both encryption duration and security.
