This paper studies the implementation of bytes multiplication in GF (2 8) based on the Rijndael resource code which is published by NIST , and analyses the characteristics of the encryption rounds, and then propose two improved schemes. Based on the technology of DSPs , we synthetically optimize the resource code and the experiments show good results.
