AES: Advanced Encryption Standard

AES is an abbreviation of Advanced Encryption Standard, also known by its original name Rijndael. It is an arrangement of standard for the encryption of electronic data set up by the U.S. National Institute of Standards and Technology (NIST) in 2001.

  • AES is a division of the Rijndael block cipher built up and expanded by two Belgian cryptographers, Vincent Rijmen and Joan Daemen, who put forward an offer to NIST for the duration of the AES selection process.
  • Rijndael is an associated group of ciphers with different key and block sizes. NIST decided on three members of the Rijndael associated group for AES, each with a block size of 128 bits, other than three different key lengths: 128, 192 and 256 bits.
  • AES has been taken up by the U.S. government and is now used globally. It has taken the place of the Data Encryption Standard (DES), which was made available in 1977. The algorithm illustrated by AES is a symmetric-key algorithm, which signifies that the identical key is used for both encryption and decryption of data.
    On November 26, 2001, in the United States, AES was proclaimed by the NIST as U.S. FIPS PUB 197 (FIPS 197). This proclamation followed a five-year standardization process in which fifteen challenging designs were offered and assessed before the Rijndael cipher was preferred as the highly appropriate.
  • On May 26, 2002, AES turned out to be effectual as a federal government standard, after authorization by the Secretary of Commerce. AES is comprised of the ISO/IEC 18033-3 standard.
  • AES is accessible in a lot of different encryption packages and is the foremost (and only) openly available cipher officially permitted by the National Security Agency (NSA) for top secret information when used in an NSA officially permitted cryptographic module.

Performance

  • For the AES selection process, the necessary criteria were high speed and low RAM.
    As the selected algorithm, AES carried out well on a broad range of hardware, from 8-bit smart cards to high-performance computers.
  • On a Pentium Pro, AES encryption needs 18 clock cycles per byte, corresponding to a throughput of about 11 Mbit/s for a 200 MHz processor. On a 1.7 GHz, Pentium M throughput is about 60 Mbit/s.
  • On Intel Core i3/i5/i7 and AMD Ryzen CPUs supporting AES-NI instruction set extensions, throughput can be multiple GB/s (even over 10 GB/s).
