This paper presents a new three-dimensional bit-level image encryption scheme, utilizing the Rubik's cube method and bit-level encryption principle to achieve image scrambling in three-dimensional space, as well as an improved two-dimensional diffusion structure to spread minor changes in the plain image to the entire cipher image.
This paper proposes a new three-dimensional bit-level image encryption scheme with Rubik's cube method (3D-BERC). In the permutation process, the Rubik's cube method and bit-level encryption principle are combined to realize the image scrambling operation in three-dimensional space. Through the contraction mapping principle, the ascending and reducing dimension operation can be implemented effectively. In the diffusion process, we design an improved two-dimensional diffusion structure, which can spread slight change in plain image to the whole cipher image. Experimental results and simulation analysis illustrate the security and the validity of the proposed scheme. (C) 2021 International Association for Mathematics and Computers in Simulation (IMACS).
