摘要
With the development of the information technology ,information security ,as well as the implementation ofthe encryption system becomes more and more complexity,and therefore new methods are explored to simplify com-plexity of the implementation. Cellular automata has the characters of simplicity of basic components ,locality of cellu-lar automata interactions ,massive parallelism of information processing ,and exhibits complex global properties, whichmakes it suitable for the application in cryptography. This paper presents a new method of encryption,the key of thenew method consists of the permutation cellular automata, the vectors inputted, and the number of the itera-tion. Evidently,it has larger kev space than other methods with only the cellular automata itself as the key.
