摘要：In this paper, cellular automata (CAs) are used to design a symmetric key cryptography system based on Bluefish algorithm, CAs are applied to generate a multiple pseudo-random numbers sequence (PNS) which is used during the encryption process. The quality of PNSs highly depends on the set of applied CA rules. This paper introduces a new method to enhance the performance of the Bluefish Algorithm. This is done by building a new structure for the 16 rounds in the original algorithm by replacing the OR operation with a new introduced operation. This structure makes use of multiple secrete keys. The principle of Cellular Automata (CA) is used to generate these multiple keys in a simple and effective way. The proposed method provides high quality encryption, and the system is very resistant to attempts of breaking the cryptography key.
