Cipher Block Chaining

Definitions

1. A block-cipher mode of operation in which each plaintext block is combined with the previous ciphertext block before encryption, commonly shortened to CBC. It was once widespread, but authenticated modes are often preferred today for better security properties.

   In plain English: An older block-encryption method where each block depends on the previous encrypted block.

   Example: "The service still used cipher block chaining mode, which required careful IV handling and separate integrity protection."
