  Advanced Encryption Standard - Wikipedia, the free encyclopedia
The cipher was developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, and submitted to the AES selection process under the name "Rijndael", a portmanteau comprising the names of the inventors.
Rijndael was a refinement of an earlier design by Daemen and Rijmen, Square; Square was a development from Shark.
AES operates on a 4×4 array of bytes, termed the state (versions of Rijndael with a larger block size have additional columns in the state).

 Rijndael - a Whatis.com definition   (Site not responding. Last check: 2007-11-07)
Rijndael (pronounced rain-dahl) is the algorithm that has been selected by the U.S. National Institute of Standards and Technology (NIST) as the candidate for the Advanced Encryption Standard (AES).
The Rijndael algorithm is a new generation symmetric block cipher that supports key sizes of 128, 192 and 256 bits, with data handled in 128-bit blocks - however, in excess of AES design criteria, the block sizes can mirror those of the keys.
Rijndael's selection has been criticized by some because the algorithm does not appear to be as secure as some of the other choices.

 CS 4803 - David Pritchett [AES - Rijndael]
Rijndael was submitted to NIST by Joan Daemen and Vincent Rijmen of Belgium.
At its simplest, Rijndael is a Square block cipher with variable block and key sizes.
Rijndael also performs other functions including a MAC algorithm, a hash function, a synchronous stream cipher, a pseudorandon number generator, and a self-syncrhonizing stream cipher.

 The Advanced Encryption Standard (Rijndael)
However, the variations of Rijndael which act on larger block sizes apparently will not be included in the actual standard, on the basis that the cryptanalytic study of Rijndael during the standards process primarily focused on the version with the 128-bit block size.
Rijndael is a relatively simple cipher in many respects.
Successive powers of 3, unlike 2, include all the values from 1 to 255, and thus several implementations of Rijndael use tables of the powers of 3, and the inverse table giving the discrete logarithm in that field, to facilitate calculations, but the round constants are still the powers of 2.

Rijndael is a block cipher, designed by Joan Daemen and Vincent Rijmen as a candidate algorithm for the AES.
The design of Rijndael was strongly influenced by the design of the block cipher Square.
Rijndael is used in the digital lecture board, developed at the university of Mannheim.

 Advanced Encryption Standard   (Site not responding. Last check: 2007-11-07)
In cryptography, the Advanced Encryption Standard (AES), also known as Rijndael, is a block cipher adopted as an encryption standard by the US government, and is expected to be used worldwide and analysed extensively, as was the case with its predecessor, the Data Encryption Standard (DES).
AES was developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, and submitted to the AES selection process under the name "Rijndael", a name derived from the names of the inventors.
Rijndael was a refinement of an earlier design by Daemen and Rijmen, Square.

 RIJNDAEL
Rijndael is the block cipher algorithm recently chosen by the National Institute of Science and Technology (NIST) as the Advanced Encryption Standard (AES).
Since Rijndael is an iterated block cipher, the encryption or decryption of a block of data is accomplished by the iteration (a round) of a specific transformation (a round function).
Rijndael is described as having a 'rich algebraic structure' which allows the cipher's security to be easily assessed in a limited time frame.

The Rijndael web page jokes that the name Rijndael was used "because we were both fed up with people mutilating the pronunciation of the names 'Daemen' and 'Rijmen'".
Rijndael's key length is defined to be either 128, 192, or 256 bits in accordance with the requirements of the AES.
The low number of rounds has been one of the main criticisms of Rijndael, but if this ever becomes a problem the number of rounds can easily be increased at little extra cost by increasing the block size and key length.

 The Advanced Encryption Standard (Rijndael)
In drawing an analogy between Rijndael and DES, it is very easy, based on a superficial glance at Rijndael, and the appearance of the Shift Row step, to view it as corresponding to the swapping of halves of the block within DES.
The key schedule for Rijndael can be carried out equally well with keys that are 160 or 224 bits long, since it only requires that the key size be a multiple of 32 bits.
Rijndael was preceded by the block cipher Square, which was somewhat similar.

The Rijndael algorithm is a symmetric iterated block cipher.
Rijndael also has a variable number of iterations or rounds: 10, 12, and 14 when the key lengths are 128, 192, and 256 respectively.
The transformations in Rijndael consider the data block as a four-column rectangular array of 4-byte vectors.

The RijnDael (pronounced Reign Dahl) algorithm was adopted in October 2000 as the Advanced Encryption System (AES) by the American National Institute of Standards and Technology (NIST), and is soon to become the Federal Information Processing Standard (FIPS).
RijnDael and DES are known as "Block" ciphers.
RijnDael encrypts blocks of 128 bits, but it is more convenient to think in terms of 16 bytes.

 Altera First to Offer Rijndael IP Cores to Accelerate Innovative Advanced Encryption Standard Algorithm   (Site not responding. Last check: 2007-11-07)
To ensure the secure transmission of information, the Rijndael IP cores utilize a higher number of bits for encrypting each key than the DES standard, thus eliminating the possibility of codes being affected by hackers.
The high-speed Rijndael decryptor core runs over 1.1 Gbps and can be implemented in Altera's APEX 20K100E device for less than $24 per unit in volume production, 70 percent less than competing ASSPs expected to be available later this year.
The low-speed Rijndael decryptor core runs over 40 Mbps and can be implemented in Altera's APEX 20K30E device for less than $13 per unit in volume production, more than an 80 percent cost reduction compared to competing ASSPs expected to be available later this year.

 Crypto proposal faces long journey
Vendors of VPN products so far have not committed to using Rijndael, but they are certain to at least offer it as an option in their VPN products next year once it's an official government standard.
Though tests showed Rijndael won't easily be broken, even NIST suggested the algorithm could benefit by having more operations added to its structure to reduce potential vulnerabilities, he says.
Unlike the four algorithms it was competing against, Rijndael is a "square structure" algorithm, and the relative novelty of the design approach means there is less knowledge about where weaknesses may reside, Viega says.

 DGEncrypt - is an implementation of the Rijndael block cipher
The Rijndael cipher is a symmetric key block cipher, which is a type of cipher that encrypts data in blocks, rather than a single bit at a time, and uses the same key for both encryption and decryption.
For its enciphering functions, dgEncrypt employs a version of Rijndael that operates on 128-bit input blocks, with keys that are 128, 192, or 256 bits in length.
A second version of the Rijndael cipher, which operates on 256-bit input blocks with 256-bit internally generated keys, is used to generate cryptographically viable random values, such as cipher keys.
