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]
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:
NSA cryptography. The vast majority of the National Security Agency 's work on encryption is classified, but from time to time NSA participates in standards processes or otherwise publishes information about its cryptographic algorithms. The NSA has categorized encryption items into four product types, and algorithms into two suites.
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 AES Corporation is an American utility and power generation company. It owns and operates power plants, which it uses to generate and sell electricity to end users and intermediaries like utilities and industrial facilities. AES is headquartered in Arlington, Virginia, and is one of the world's leading power companies, generating and ...

In her career, she won two singles titles and one doubles title on the WTA Tour, as well as 14 singles and ten doubles titles on the ITF Women's ...
Format-preserving encryption. In cryptography, format-preserving encryption ( FPE ), refers to encrypting in such a way that the output (the ciphertext) is in the same format as the input (the plaintext ). The meaning of "format" varies. Typically only finite sets of characters are used; numeric, alphabetic or alphanumeric.
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.
