Twodimensional cellular automata based bidirectional toggle parallel encryption model
基于二维元胞自动机的双向触发并行加密模型

Based upon the properties of two-dimensional cellular automata,this paper proposed a bidirectional toggle parallel encryption model.Simulation shows that in comparison with the one-dimensional coupled toggle cellular automata,the method proposed here expands the key spaces largely while slowing the speed of encryption and decryption reasonably,so it has very high efficiency of expanding the key spaces largely through consuming a little bit more time,and improves the robusticity and the suitability commendably.
