WebData Encryption Standard is a symmetric-key algorithm for the encrypting the data. It comes under block cipher algorithm which follows Feistel structure. Here is the block diagram of Data Encryption Standard. Fig1: … 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 cryptographic transformation (encryption or decryption) of one fixed-length group of bits called … 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 National Institute of Standards and Technology (NIST) … 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 … See more • Disk encryption • Message authentication code • Authenticated encryption • One-way compression function 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 … 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 Many more modes of operation for block ciphers have been suggested. Some have been accepted, fully described (even standardized), and … See more
