摘要

提出了一种新的图形密码系统，可以对任意颜色定义的图像进行加密。该密码系统基于一维可逆元胞自动机。原始图像和加密图像由相同的调色板定义，解密后的图像与原始图像相同，即没有分辨率和清晰度的损失。密码系统对最重要的攻击是安全的:暴力攻击、统计攻击、选择明文攻击和已知明文攻击。

A new graphic cryptosystem based on one-dimensional memory cellular automata

A new graphic cryptosystem for encrypting images defined by any number of colors is presented. The cryptosystem is based on a one-dimensional reversible cellular automaton. The original and the encrypted image are defined by the same color palette and the decrypted image is identical to the original one, i.e., it has no loss of resolution nor definition. The cryptosystem is secure against the most important attacks: brute-force attacks, statistical attacks, chosen-plaintext attacks and known-plaintext attacks.
