1997年9月，NIST征集AES方案，以替代DES。 1999年8月，以下5个方案成为最终候选方案：MARS, RC6, Rijndael, Serpent, Twofish。 2000年10月，由比利时的Joan Daemen和Vincent Rijmen提出的算法最终胜出。（ Rijndael 读成Rain Doll。） http://www.esat.kuleuven.ac.be/~rijmen/rijndael/-September 1997, NIST AES assembly program to replace DES. In August 1999, the following five programs become final candidate : MARS, RC6, Rijndael, Serpent, Twofish. In October 2000, from Belgium J.J.K.Daemen3 Joan and Vincent Rijmen proposed algorithm eventually win. (Rijndael read Rain Doll.) Http://www.esat.kuleuven.ac.be/ ~ rijmen/rijndael /
