AES is a symmetric-key algorithm for encrypting electronic data, with key sizes of 128, 192 or 256 bits. AES is a variant of Rijndael, a family of ciphers developed by Daemen and Rijmen, and is the first cipher approved by the U.S. NSA for top secret information.
AES3 is a standard for the exchange of digital audio signals between professional audio devices, jointly developed by the Audio Engineering Society (AES) and the European Broadcasting Union (EBU). It can carry two channels of PCM audio over balanced or unbalanced lines or optical fiber, and has variants such as S/PDIF and AES-3id.
Learn how the AES algorithm was chosen as a standard by NIST from 1997 to 2000, after a public and transparent competition involving 15 candidates. AES is a symmetric block cipher with 128-bit blocks and 128-, 192-, or 256-bit keys.
AES is a block cipher algorithm that can be used in various modes of operation. Learn about the different libraries, applications and modes of AES, such as CBC, CTR, GCM and more.
Learn about the AES instruction set, a set of instructions that perform AES encryption and decryption efficiently. Find out which Intel processors support AES-NI, the first major implementation of AES-NI, and compare it with other architectures and hardware accelerators.
Learn how the Advanced Encryption Standard expands a short key into a number of round keys for encryption. See the key schedule algorithm, the round constants, and the key schedule schematic for different AES variants.
