Rijndael Arithmetic Analyse and Optimize

With the expert encrypting standard Rijndael arithmetic acquiring the extensive support and application in every walk of life, the problems of the safety and quick implement of the Rijndael arithmetic seem to be particularly outstanding. This paper carried on an analytical research to the Rijndael arithmetic, which can carry out to crack to that arithmetic in validated time; through several transform rounds, the encryption arithmetic to achieve rate is not high . This paper carried on optimize to the S-boxes and transform round, and enhanced the security strength and efficiency of the algorithm; finally, verified this paper to give of optimize methods.
