摘　　要：本文先对Rijndael加密算法的密钥扩展算法进行了简要阐述,之后给出了密钥扩展算法的递归模型并对其进行了分析,最后指出Rijndael加密算法与密钥扩展算法之间的同步特性,并进而阐述了实现加密算法时应用该特性可以节约消耗的时间和空间。This paper introduces the key expansion of the encryption algorithm rijndael. Then it puts forward the mathematical model of the key expansion and analyzes the model. Finally, it points out a synchronization between the encryption algorithm rijndael and the key expansion, on the basis of which the paper proposes that it saves time and space to make use of the synchronization when we implement the encryption algorithm rijndael.
