The bibliographic entry was discovered and compiled by a machine, and published without a person checking it against the publication. The publication itself is the authors' own work — this badge says nothing about it.
From OpenAlex, which stores abstracts as an
index of words and their positions: what is shown is rebuilt from that,
and reads fluently whether or not it is what the author wrote.
Abstract
The Advanced Encryption Standard (AES) specifies a FIPS-approved cryptographic algorithm that can be used to protect electronic data. The AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information. Encryption converts data to an unintelligible form called ciphertext; decrypting the ciphertext converts the data back into its original form, called plaintext. The AES algorithm is capable of using cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits.
