__Rijndael block cipher__

A block cipher that was selected to replace DES. The Rijndael cipher allows the use of three key strengths: 128 bits, 192 bits, and 256 bits.

Advanced Encryption StandardAdvanced Encryption Standard, a new encryption standard, whose development and selection was sponsored by NIST, that will support key lengths of 128, 192, and 256 bits. FIPS approved cryptographic algorithm that is a symmetric block cipher using cryptographic key sizes of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. The encryption standard selected in October 2000 by the National Institute of Standards and Technology (NIST) that is based on the Rijndael cipher.

A private key cryptosystem published by the National Institutes of Standards and Technology (NIST). DES is a symmetric block cipher with a block length of 64 bits and an effective key length of 56 bits. DES has been used commonly for data encryption in the forms of software and hardware implementation. A standard cryptosystem proposed in 1977 for all government communications. DES and 3DES were superseded by Advanced Encryption Standard (AES) in December 2001. Cryptographic algorithm, designed for the protection of unclassified data and published by the National Institute of Standards and Technology (NIST) in Federal Information Processing Standard (FIPS) Publication 46. (FIPS 463 withdrawn 19 May 2005) (. See Triple DES) and CNSS Advisory IA/0204 Revised March 2005)

Product cipher that, like DES, operates on 64bit data blocks. There are several forms, each of which uses the DES cipher 3 times. Some forms use two 56bit keys, some use three. (. See NIST FIPS 463 and CNSSAM IA/0204)

A mode in which the DES algorithm is used to encrypt the preceding block of cipher text. This block is then XORed with the next block of plain text to produce the next block of cipher text.

A block cipher that was developed in response to complaints about the insufficient key length of the DES algorithm. IDEA operates on 64-bit blocks of plain/cipher text, but it begins its operation with a 128-bit key.
