sequence of bytes in State.

Question

Quizplus · Accepted Answer

AddRoundKey and InvMixColumn are transformations used in AES encryption and decryption, respectively. AddRoundKey performs a bitwise XOR operation with the round key, which does not alter the sequence of bytes, only their values. InvMixColumn operates on the column level, mixing the data within each column, but it also does not change the sequence of bytes in the State; it changes the values of the bytes through a reversible linear transformation.
