中文摘要：

基于二维细胞自动机提出了一种新的秘密图像共享方案，该方案把秘密图像作为细胞自动机的一个初始配置，通过利用二维”阶可逆存贮细胞自动机进行分解成”为份的影子图像，再利用其逆细胞自动机进行反向迭代来重构所共享的秘密图像。分析表明，该方案实现简单，在计算上是安全的，并且是一个完备的（n，n）方案。

英文摘要：

Based on the bidimensional cellular automata,a new secret image sharing scheme is proposed in this paper. The secret image is considered as one of the initial configurations of the bidimensional cellular automata,The n shadow images of the secret image are made by the bidimensional reversible cellular automata with memory of order n. The backward iteration of the bidimensional reversible cellular automata with memory of order n is used to recover the shared secret image. Analysis show the proposed scheme can be implemented easily,and is a computationally secure and perfect （n,n） scheme.
