WebNow by using a grouping that uses both InvMixColums and AddRoundKey at the end of the round, we will swap the positions of InvSubBytes with InvShiftRows and swap the positions of InvMixColumns with AddRoundKey to get this equivalent description instead (List 3.8, page 49), with again a shorter last round, and an initial AddRoundKey: Weblowing order: InvShiftRows, InvSubBytes, AddRoundKey and InvMixColumns. The SubBytes and ShiftRows operations in Fig. 1 are reordered compared to the cipher round depicted in the standard [29]. Their order is not signiﬁcant because SubBytes operatesonsinglebytes,andShiftRows reordersbyteswithoutaltering them.
