A method to encrypt 3D solid objects based on three-dimensional cellular automata

Abstract

In this work a novel encryption algorithm to assure the confidentiality of 3D solid objects is introduced. The encryption method consists of two phases: The confusion phase and the diffusion phase. In the first one a three-dimensional chaotic Cat map is applied N times, whereas in the diffusion phase a 2-th order memory reversible 3D cellular automata is evolved T times during M rounds. The encryption method is shown to be secure against the most important cryptanalytic attacks: statistical attacks, differential attack, etc.
