Advanced Encryption Standard

Technique

A symmetric-key block cipher adopted as a United States federal standard in 2001, encrypting data in fixed-size blocks under a shared secret key; the most widely used cipher for protecting data at rest and in transit today.

Facts
Origin Year
2001 1
Core Principle
A symmetric-key block cipher standard, based on the Rijndael cipher, that encrypts data in fixed 128-bit blocks using a secret key of 128, 192 or 256 bits, with the same key used for both encryption and decryption. 1

  • Lead section, first paragraph
    is a specification for the encryption of electronic data established by the US National Institute of Standards and Technology (NIST) in 2001.
  • Lead section, second paragraph
    The algorithm described by AES is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data.
