Block cipher mode of operation - Wikipedia

The simplest (and not to be used anymore) of the encryption modes is the electronic codebook (ECB) mode (named after conventional physical codebooks). The message is divided into blocks, and each block is encrypted separately. The disadvantage of this method is a lack of diffusion. See more In cryptography, a block cipher mode of operation is an algorithm that uses a block cipher to provide information security such as confidentiality or authenticity. A block cipher by itself is only suitable for the secure … See more The earliest modes of operation, ECB, CBC, OFB, and CFB (see below for all), date back to 1981 and were specified in FIPS 81, DES Modes of Operation. In 2001, the US See more A block cipher works on units of a fixed size (known as a block size), but messages come in a variety of lengths. So some modes (namely ECB and CBC) require that the final block be padded before encryption. Several padding schemes exist. The simplest is to add See more "Error propagation" properties describe how a decryption behaves during bit errors, i.e. how error in one bit cascades to different decrypted bits. Bit errors may occur … See more An initialization vector (IV) or starting variable (SV) is a block of bits that is used by several modes to randomize the encryption and hence to produce distinct ciphertexts even if … See more Authenticated encryption with additional data (AEAD) modes A number of modes of operation have been designed to combine secrecy and authentication in a single cryptographic primitive. Examples of such modes are , integrity-aware … See more Many more modes of operation for block ciphers have been suggested.

From reading, WebJan 28, 2012 · The ECB block cipher mode of operation is best used on randomized data, where there is no link between any of the plain text blocks. In practice, only randomized secret keys (without any additional / meta data) and random challenges (in challenge response protocols) fit that bill.
