The encryption algorithm performs a preliminary processing step that's called AddRoundKey in the specification. AddRoundKey performs a byte-by-byte XOR operation on the State matrix using the first four rows of the key schedule, and XORs input State[r,c] with round keys table w[c,r]. ...
of EP1271839 A round processing unit in an encryption circuit comprises: a first Round Key Addition circuit (204) that adds a round key value to input data; an intermediate register/Shift Row transformation circuit (206) that temporarily stores the output of the first Round Key Addition circuit...
