AES has been adopted by the U.S. government. It supersedes the Data Encryption Standard (DES), [9] which was published in 1977. The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data.
Advanced Encryption Standard process. 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 ...
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.
AEGIS is an example fast (if the AES instruction set is present), key-committing AEAD. It is possible to add key-commitment to an existing AEAD scheme. Approaches to authenticated encryption Encrypt-then-MAC (EtM) EtM approach. The plaintext is first encrypted, then a MAC is produced based on the resulting ciphertext.
Advanced electronic signature, an EU-compliant electronic signature system (alternatively AdES) Advanced Encryption Standard, or Rijndael, a specification for the encryption of electronic data. Agricultural experiment station, a scientific research center. Algebraic entry system, a calculator input method. Alkaline earth silicate, a mineral wool.
AES key schedule for a 128-bit key. Define: N as the length of the key in 32-bit words: 4 words for AES-128, 6 words for AES-192, and 8 words for AES-256; K 0, K 1, ... K N-1 as the 32-bit words of the original key; R as the number of round keys needed: 11 round keys for AES-128, 13 keys for AES-192, and 15 keys for AES-256; W 0, W 1, ...
NIST Special Publication SP800-38D defining GCM and GMAC. RFC 4106: The Use of Galois/Counter Mode (GCM) in IPsec Encapsulating Security Payload (ESP) RFC 4543: The Use of Galois Message Authentication Code (GMAC) in IPsec ESP and AH. RFC 5288: AES Galois Counter Mode (GCM) Cipher Suites for TLS.
Disk encryption theory. Disk encryption is a special case of data at rest protection when the storage medium is a sector-addressable device (e.g., a hard disk). This article presents cryptographic aspects of the problem. For an overview, see disk encryption. For discussion of different software packages and hardware devices devoted to this ...
Structure. Feistel network. Rounds. 48 DES-equivalent rounds. In cryptography, UES ( Universal Encryption Standard) is a block cipher designed in 1999 by Helena Handschuh and Serge Vaudenay. They proposed it as a transitional step, to prepare for the completion of the AES process .
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.
