No need to show work, answer is enough



In this and the following four questions, we compare AES to DES from the structure as well as diffusion and confusion perspectives. For each specified element of DES, please indicate the most comparable element in AES if no comparable element exists in AES, please select "Not needed in AES". XOR of subkey material with the output of the E table in DES is most comparable with which element in AES? - The following two figures are for your reference DES single round illustration (for your reference): 32 bits L-1 32 bits R-1 28 bits G-1 28 bits D-1 Expansion permutation (Etable) 48 Left shines) Left shit) F XOR Permutation contraction (Permuted choice 2) 48 Substitution/choice (S-box) Permutation (P) 32 XOR AES single round illustration for your reference): State Satbyts OO Shrows Mix Columns Add RoundKey Permutation P in DES is most comparable with which element in AES?
