摘　　要：根据二维触发元胞自动机的特性,提出了一种二维元胞自动机双触发并行加//解密模型。仿真实验表明:与一维耦合触发元胞自动机相比,二维元胞自动机双触发并行加密模型在适度减慢加/解密速度的情况下,大大提高了密钥空间,具有极高的时间换空间的效率,很好地提高了健壮性和实用性。Based upon the properties of two-dimensional cellular automata, this paper proposed a bidirectional toggje 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.
