The main loop of the AES encryption algorithm performs four different operations on the State matrix, called SubBytes, ShiftRows, MixColumns, and AddRoundKey in the specification. The AddRoundKey operation is the same as the preliminary AddRoundKey except that each time AddRoundKey is called, th...
The operation of the AES algorithm is shown inFigure 36-2. The encryption step uses a key that converts the data into an unreadable ciphertext, and then the decryption step uses the same key to convert the ciphertext back into the original data. This type of key is asymmetric...
