The Advanced Encryption Standard (AES), also known by its original name, Rijndael, is a specification for the encryption of electronic data established by the National Institute of Standards and Technology of the United States (NIST) in 2001.
AES is a subset of Rijndael [6] encryption developed by two Belgian cryptographers, Vincent Rijmen and Joan Daemen, who submitted a proposal to NIST during the AES selection process. Rijndael is a family of figures with different key and block sizes.
For AES, NIST selected three members of the Rijndael family, each with a 128-bit block size, but three different key lengths: 128, 192, and 256 bits.
AES has been adopted by the government of the United States and is now used around the world. The algorithm described by AES is a symmetric key algorithm, which means that the same key is used to encrypt and decrypt the data.
In the United States, AES was announced by NIST as FIPS PUB 197 (FIPS 197) on November 26, 2001. This announcement followed a five-year standardization process in which fifteen competing designs were presented and evaluated, before Rijndael figure was selected as the most appropriate.
AES came into force as a federal government standard on May 26, 2002, after approval by the Secretary of Commerce. AES is included in ISO / IEC 18033-3. AES is available in many different encryption packages and is the first (and only) publicly accessible encryption approved by the National Security Agency (NSA) to obtain secret information when used in an NSA-approved cryptographic module.
