Advanced Encryption Standard

(cryptography, algorithm)
(AES) The NIST's replacement for the Data Encryption Standard (DES). The Rijndael /rayn-dahl/ symmetric block cipher, designed by Joan Daemen and Vincent Rijmen, was chosen by a NIST contest to be AES.

AES is Federal Information Processing Standard FIPS-197.

AES currently supports 128, 192 and 256-bit keys and encryption blocks, but may be extended in multiples of 32 bits.

AES

(Advanced Encryption Standard) A U.S. government encryption standard supported by the National Institute of Standards & Technology (NIST). AES is a cryptographic cipher that uses a block length of 128 bits and key lengths of 128, 192 or 256 bits. Officially replacing the Triple DES method in 2001, AES uses the Rijndael algorithm developed by Joan Daemen and Vincent Rijmen of Belgium. AES can be encrypted in one pass instead of three, and its key size is greater than Triple DES's 168 bits. In early 1997, the NIST invited cryptographers to submit an advanced algorithm. In late 2000, the Rijndael (pronounced "rine-doll") symmetric block cipher algorithm was selected out of submissions by 21 teams from 11 countries. See cipher, cryptography, NIST, DES and AES/CCMP.

Founded in 1948, technical standards have been continually developed under its auspices. AES is dedicated to ensuring that audio quality is maintained in the digital world. See AES/EBU.

Since RSA, the K300 has passed FIPS 197 and IP57 certifications.
The new Kingston USB drives are both 256-bit AES hardware encrypted and FIPS certified (DT4000G2DM is FIPS 140-2 Level 3 validated; DTVP30DM is FIPS 197 certified) to ensure maximum corporate and personal data security.
Deep Security was also certified for FIPS 197, FIPS 180-3 and FIPS 186-3 standards as part of this process corresponding to AES, SHA-1/SHA-256 and RSA cryptographic algorithms - respectively.
Encryption: Advanced Encryption Standard (AES) - FIPS 197 Digital Signature: Elliptic Curve Digital Signature Algorithm (ECDSA) - FIPS 186-2
AES-128 is specified in a government document called the Federal Information Processing Standards publication (FIPS), and FIPS 197 was adopted by the National Institute of Standards and Technology (NIST) in 2001.
It uses full-strength PKI technology and the FIPS 197 approved AES encryption algorithm at its strongest key length of 256 bits.
Successful completion of the AES validation tests is required to claim conformance to the AES as specified in FIPS 197. When applied to implementations under test (IUTs), the validation tests determine the correctness of the algorithm implementation.
These expanded capabilities are compatible with and support the strengthened security requirements of FIPS 197, Advanced Encryption Standard.
The slowdown in the announcement of new DES products apparently was due to the impending adoption of FIPS 197, AES, which was approved by the Secretary of Commerce on Dec.
