Cipher Block Chaining (CBC) Mode: A mode of operation for block ciphers where each block of plaintext is XORed with the previous ciphertext block before being encrypted. This method ensures that identical plaintext blocks will encrypt to different ciphertext blocks, enhancing security. It uses an initialization vector (IV) for the first block to ensure randomness.
