CBC mode – Block Ciphers and Their Modes of Operation
14.4.2 CBC mode Cipher Block Chaining (CBC), illustrated in Figure 14.9, is a mode of operation that chains the ciphertext blocks. CBC encryption is probabilistic, meaning that two identical plaintext blocks will result in two different ciphertext blocks: Figure 14.9: Working principle of the CBC mode of operation The initial ciphertext block c0 is set…
