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]
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 ...
This result has been further improved to 2 126.0 for AES-128, 2 189.9 for AES-192 and 2 254.3 for AES-256, which are the current best results in key recovery attack against AES. This is a very small gain, as a 126-bit key (instead of 128 bits) would still take billions of years to brute force on current and foreseeable hardware.
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.
Z (or B) : 11101000 2 if previous time slot was 0, 00010111 2 if it was 1. (Equivalently, 10011100 2 NRZI encoded.) Marks a word for channel A (left) at the start of an audio block. The three preambles are called X, Y, Z in the AES3 standard; and M, W, B in IEC 958 (an AES extension).

Security level. In cryptography, security level is a measure of the strength that a cryptographic primitive — such as a cipher or hash function — achieves. Security level is usually expressed as a number of " bits of security" (also security strength ), [1] where n -bit security means that the attacker would have to perform 2 n operations ...
The advanced electronic signature is one of the standards outlined in eIDAS. For an electronic signature to be considered as advanced, it must meet several requirements: [3] [4] The signatory can be uniquely identified and linked to the signature. The signatory must have sole control of the signature creation data (typically a private key) that ...
