WebbThe RC4 digit uses a key that can initialize an array of 256 boxes. The algorithm that allows to initialize the array with the key key is: The array t can then be used to generate a … WebbTable 5.3 Key Expansion for AES Example. used to generate the auxiliary word used in key expansion. We begin, of course, with the key itself serving as the round key for round 0. Next, Table 5.4 shows the progression of State through the AES encryption process. The first column shows the value of State at the start of a round.
