Jiliang Lv, Qinggang Xie, Jie Zhang · Physica Scripta · 2025
Abstract A six-dimensional chaotic system is constructed by introducing nonlinear functions. Additionally, the system proposed is confirmed through analog circuits and field-programmable gate arrays (FPGA) digital circuits. A double-block encryption algorithm is proposed that combines the improved 2D Logistic mapping with the six-dimensional chaotic system proposed to perform DNA computation on image pixels, achieving a ‘one image, one key’ effect for secure and efficient encryption of images.
