Webstructions (note that ShiftRows and SubBytes, InvShiftRows and InvSubBytes com-mute). 4.1 Design for software exibility Software exibility implies that the architecture should be able to support all of the current usage models for AES. Indeed, it … 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:
