Cipher model
WebNov 29, 2024 · When talking about encryption and message authentication codes, a block cipher is a practical instantiation of a pseudorandom permutation family. When talking about hash functions, however, people often talk about block ciphers in the stronger sense of the ideal cipher model, where a block cipher is modeled as a family of random permutations. 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.
