What is the Advanced Encryption Standard (AES)?
What will be an ideal response?
The Advanced Encryption Standard (AES) is a symmetric cipher that was approved by the NIST in late 2000 as a replacement for DES. AES performs three steps on every block (128 bits) of plaintext. Within step 2, multiple rounds are performed depending upon the key size: a 128-bit key performs 9 rounds, a 192-bit key performs 11 rounds,
and a 256-bit key, known as AES-256, uses 13 rounds. Within each round, bytes are substituted and rearranged, and then special multiplication is performed based on the new arrangement. To date, no attacks have been successful against AES.
