AES is based on a design principle known as a substitution–permutation network, and is efficient in both software and hardware. Unlike its predecessor DES, AES does not use a Feistel network. AES is a variant of Rijndael, with a fixed block size of 128 bits, and a key size of 128, 192, or 256 bits.
The Rijndael S-box is a substitution box (lookup table) used in the Rijndael cipher, on which the Advanced Encryption Standard (AES) cryptographic algorithm is based.
The Advanced Encryption Standard (AES), the symmetric block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process lasting from 1997 to 2000 that was markedly more open and transparent than its predecessor, the Data Encryption Standard (DES).
The basic operations of the LRW mode (AES cipher and Galois field multiplication) are the same as the ones used in the Galois/Counter Mode (GCM), thus permitting a compact implementation of the universal LRW/XEX/GCM hardware.
AES key schedule. The Advanced Encryption Standard uses a key schedule to expand a short key into a number of separate round keys. The three AES variants have a different number of rounds.
In 2013, the CAESAR competition was announced to encourage design of authenticated encryption modes. [13] In 2015, ChaCha20-Poly1305 is added as an alternative AE construction to GCM in IETF protocols.
The Commercial National Security Algorithm Suite ( CNSA) is a set of cryptographic algorithms promulgated by the National Security Agency as a replacement for NSA Suite B Cryptography algorithms.
An advanced electronic signature (AES or AdES) is an electronic signature that has met the requirements set forth under EU Regulation No 910/2014 (eIDAS-regulation) on electronic identification and trust services for electronic transactions in the European Single Market.
The Alliance of Sahel States (AES/ASS) is a mutual defense pact created between Mali, Niger, and Burkina Faso on 16 September 2023.
In cryptography, ARIA is a block cipher [1] designed in 2003 by a large group of South Korean researchers. [2] In 2004, the Korean Agency for Technology and Standards selected it as a standard cryptographic technique. The algorithm uses a substitution–permutation network structure based on AES.
