WebHistoire et normalisation. Les premiers modes de fonctionnement, ECB, CBC, OFB et CFB (voir ci-dessous pour tous), remontent à 1981 et ont été spécifiés dans FIPS 81, Modes d'opération DES.. En 2001, le National Institute of Standards and Technology (NIST) a révisé sa liste de modes de fonctionnement approuvés en incluant AES comme chiffrement par … CBC has been the most commonly used mode of operation. Its main drawbacks are that encryption is sequential (i.e., it cannot be parallelized), and that the message must be padded to a multiple of the cipher block size. One way to handle this last issue is through the method known as ciphertext stealing. 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, … 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 See more "Error propagation" properties describe how a decryption behaves during bit errors, i.e. how error in one bit cascades to different decrypted … 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 … 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. Some have been accepted, fully described (even standardized), and are in use. Others have been found insecure, and should never be used. Still others don't categorize as confidentiality, … See more long towers
