The DES algorithm uses the following steps, which were well-explained by J. Orlin Grabbe in his article The DES Algorithm Illustrated (Laissez Faire City Times, Vol 2, No. 28).

Today AES is used in more than 1700 NIST-validated products and thousands of others; it has been standardized by NIST, ISO, and IEEE and it has been approved by the U.S. National Security Agency ...

ASC X9 has released a new standard, X9.24-3, that allows the use of the AES DUKPT algorithm to enhance security in retail financial transactions.

AES-XTS, or as it is sometimes referred XTS-AES, is the de-facto cryptographic algorithm for protecting the confidentiality of data-at-rest on storage devices. It is a standards-based symmetric ...

In September 1997, the NIST issued a request for possiblecandidates for a new AES to replace the DES. In August 1998, NISTselected 15 candidate algorithms and in August 1999, announced fivefinalists: ...

Each of the algorithms submitted for the AES competition was required to support key sizes of 128, 192 and 256 bits. For a 128-bit key size, there are approximately 340 undecillion (340 followed ...

The winner of the competition was Belgian algorithm Rijndael, and accordingly, Rijndael is known as AES. The CSA explicitly required NIST to seek the advice and guidance of the National Security ...

The goal of AES was not only to select a new cipher algorithm but also to dramatically increase both the block and key size compared with DES. Where DES used 64-bit blocks, AES uses 128-bit blocks.

Researchers from Microsoft and the Dutch Katholieke Universiteit Leuven have discovered a way to break the widely used Advanced Encryption Standard (AES), the encryption algorithm used to secure ...

In 2001, NIST issued AES, known as FIPS 197. AES has a block length of 128 bits and supports key lengths of 128, 192 and 256 bits.
