Cryptography matrix
WebThe Rijndael cipher works by first putting the 128-bit block of plain text into a 4-byte-by-4-byte matrix, termed the state, that changes as the algorithm proceeds through its steps. The first step is to convert the plain text block into binary and then put it into a matrix, as shown in Figure 8.3. Figure 8.3. The Rijndael matrix.
