耦合触发细胞自动机加密算法研究

该文提出了1种新的耦合触发细胞自动机加密模型。根据耦合和触发细胞自动机的性质，采用相互作用的n个细胞自动机作为一个整体，构造出耦合触发细胞自动机加密系统。计算机仿真结果表明：该算法极大地提高了密钥空间，有效地阻止了蛮力攻击；同时，加密时随机数的引入使得攻击者不可能获得唯一的明文密文对，从而有效地抵御了已知明文攻击和选择密文的攻击。

Encryption Algorithm Based on Coupled Toggle Cellular Automata

A novel cryptographic model based on the coupled toggle cellular automata is proposed. According to the characteristics of coupled and toggle cellular automata, a cryptographic system is constructed by using the n interacted cellular automatas as an entity, The simulation results indicate that the cryptosystem can enlarge the key space and resist the brute attack. The introduction of the random numbers makes attackers not obtain unique plaintext and corresponding ciphertext, which effectively resists known-plain attack and chosen-cipher attack.
