Status of approval:
|
|
|
FIPS PUBS 197 has been approved by Secretary of Commerce.

Justification for the specific reference:
|
|
|
In specification of the procedures for secure key derivation, data encryption, data encryption key encryption, management flow integrity verification, Recommendation G.989.3 established AES as the underlying block cipher of the corresponding cryptographic methods. NIST publication FIPS 197 provides an authoritative specification of AES encryption. It has been used previously as a specification of the block cipher in G.984.3 and G.987.3.

Other useful information describing the "Quality" of the document:
|
|
|
AES is the final outcome of a cryptographic algorithm contest with Rijndael chosen as the AES candidate. AES has undergone the NIST review procedures. An AES reference implementation is available at http://csrc.nist.gov/encryption/aes/rijndael/
FIPS-197 was published in November 2001.
