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.

本文试图提出一种满足雪崩扩散和混淆特性的公共云使用非均匀元胞自动机的一次性填充块加密。研究发现，通过结合非均匀和可逆元胞自动机机制，可以在公共云中生成强大的主密钥。仿真结果表明，该方法具有较大的密钥空间，保护了传统的暴力破解和选择明文攻击，同时具有更好的访问云数据的执行时间。理论分析证实，所提出的基于元胞自动机的随机密钥生成解决方案具有可接受的安全性。
