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.
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). This process won ...
The key schedule. 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. K0, K1, ... KN-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 [note 4]

AES3. AES3 is a standard for the exchange of digital audio signals between professional audio devices. An AES3 signal can carry two channels of pulse-code-modulated digital audio over several transmission media including balanced lines, unbalanced lines, and optical fiber. [1]
UES. 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 . UES was designed with the same interface as AES: a block size of 128 bits and key size of 128, 192, or 256 bits.
For AES-128, the key can be recovered with a computational complexity of 2 126.1 using the biclique attack. For biclique attacks on AES-192 and AES-256, the computational complexities of 2 189.7 and 2 254.4 respectively apply. Related-key attacks can break AES-256 and AES-192 with complexities 2 99.5 and 2 176 in both time and data, respectively.
The Federal Information Processing Standard Publication 140-2, ( FIPS PUB 140-2 ), [1] [2] is a U.S. government computer security standard used to approve cryptographic modules. The title is Security Requirements for Cryptographic Modules. Initial publication was on May 25, 2001, and was last updated December 3, 2002.
