Most encryption algorithms use the block cipher method, which codes fixed blocks of input. Others use the stream method, which encrypts one bit at a time.

The best known block cipher is AES, short for Advanced Encryption Standard. Ciphertext produced with 128-bit, 192-bit, and 256-bit AES go through 10 rounds, 12 rounds, and 14 rounds respectively.

Data Encryption Algorithms The encryption algorithms as well as the SAS Proprietary algorithm are defined as follows: RC2 A proprietary algorithm developed by RSA Data Security, Inc., RC2 is an ...

Sony announced late last week that they have invented a new encryption mechanism known as "CLEFIA," a block cipher algorithm designed to help content producers deliver "advanced copy protection ...

The National Security Agency (NSA) is offering two families of encryption algorithms, known as block ciphers, intended to provide a level of security for such processes as authentication or ...

Types of symmetric encryption included Data Encryption Standards (DES), a low-level encryption block cipher algorithm that converts plain text into blocks of 64 bits and converts them to ...

Proven hash algorithms like SHA-2, SHA-3, SM3, or (AES-)GHASH can be used for integrity protection purpose. Once one or more of the cipher algorithms are selected, the choice of secure modes of ...

The goal of AES was not only to select a new cipher algorithm but also to dramatically increase both the block and key size compared with DES. Where DES used 64-bit blocks, AES uses 128-bit blocks.
