Abstract

An efficient hierarchical chaotic image encryption algorithm and its VLSI architecture are proposed. Based on a chaotic system and a permutation scheme, all the partitions of the original image are rearranged and the pixels in each partition are scrambled. Its properties of high security, parallel and pipeline processing, and no distortion will be analysed. To implement the algorithm, its VLSI architecture with pipeline processing, real-time processing capability, and low hardware cost is designed and the FPGA realisation of its key modules is given. Finally, the encrypted image is simulated and its fractal dimension is computed to demonstrate the effectiveness of the proposed scheme.
