Design of New One-Time Pad Encryption Using Non-Uniform Cellular Automata With Parity Bit

Abstract

This paper attempts to propose a one-time pad block encryption using non-uniform cellular automata for the public cloud which satisfies avalanche diffusion and confusion properties. It is found that by combining non-uniform and reversible cellular automata mechanisms, a robust master key in the public cloud could be generated. The simulation results show that the proposed method has large key space and protects the traditional brute force and chosen plaintext attacks in addition to having better execution time for accessing cloud data. The theoretical analysis confirmed that the proposed cellular automata–based random key generation solution was marked by acceptable security.
