The Advanced Encryption Standard ( AES ), also known by its original name Rijndael ( Dutch pronunciation: [ˈrɛindaːl] ), [5] is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001. [6]
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.
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 ...
First, the input is mapped to its multiplicative inverse in GF(2 8) = GF(2) [x]/(x 8 + x 4 + x 3 + x + 1), Rijndael's finite field. Zero, as the identity, is mapped to itself. This transformation is known as the Nyberg S-box after its inventor Kaisa Nyberg. The multiplicative inverse is then transformed using the following affine transformation:
Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message is impossible to understand without the knowledge of a secret key) and authenticity (in other words, it is unforgeable: the encrypted message includes an authentication tag that the sender can calculate only while possessing the secret key).
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. Each variant requires a separate 128-bit round key for each round plus one more. [note 1] The key schedule produces the needed round keys from the initial key.
The company, owned by private-equity firm Permira, has gotten favorable feedback from potential investors, who expect the company to be valued at about $3.3 billion, the equivalent of 11 times its ...
