资源说明:In order to improve the known cryptanalysis, a new attack on 7-round Rijndael-128/256 is proposed by changing the order of round transformation , using the alternative representation of the round keys, exploiting the relationship of keys, and designing the key di_erence pattern properly. By using the new attack scheme, the time complexity is reduced from 2192 to 288, and the data complexity is reduced from 2226 to 277.
