Triple Layer RGB Image Encryption Algorithm Utilizing Three Hyperchaotic Systems and Its FPGA Implementation
Open accessAbstract
Image encryption is essential for protecting sensitive visual data during transmission and storage. This article introduces a novel image encryption technique that utilizes three hyperchaotic systems: a memristor system, a hyperchaotic 7D system, and an Erbium-doped fiber laser-based system. The algorithm takes advantage of the complex dynamics and random-like behavior of these systems to implement a robust three-layer encryption process. In each layer, a pseudo-random number generator is used to construct an S-box and an encryption key, which are subsequently applied to the image data. The proposed encryption scheme is implemented in software using Wolfram Mathematica® version 13.1 and in hardware using an AMD Virtex-7 FPGA VC707, achieving encryption rates of 9.7 Mbps and 0.67 Gbps, respectively. Experimental results demonstrate the scheme’s effectiveness in terms of encryption quality, resistance to various cryptanalysis attacks, and a high computational efficiency. The proposed method shows significant potential for secure image transmission and storage applications.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
