After the construction of s-boxessatisfying some good cryptographic properties,the Bytesub step in rijndaelalgorithm was improved based on the dynamical selection of s-boxes depending on the round *** improved algorithm has been proved to have stronger ability to resist differential ***,the avalancheprobability of thisalgorithm is more reasonable and the design method is a challenge to the Kerckhoff hypothesis.
