A secret key-based cryptosystem. To use DES for communication, both the sender and the receiver must know the same secret key, which is used to provide both encryption and decryption of the message. DES is the most well known and widely used cryptographic system in the world. It was originally developed by IBM and was endorsed by the U.S. government in 1977 as an official standard.

(abbreviation: DES) A popular, standard encryption scheme.

The NIST Federal Information Processing Publication (FIPS Pub. 46) standard which defines the use of the Data Encryption Algorithm. The cryptographic method used by the STAR Network for data Encryption.

An encryption algorithm developed by IBM and the U.S. government in the 1970's as an official standard.

Federal Information Processing Standard publication 46. A US standard defining a cryptosystem for use by the US Federal Government. Popularly known as DES, this cryptosystem is widely used in payment systems

Definition 1) (DES) An unclassified crypto algorithm adopted by the National Bureau of Standards for public use. Definition 2) A cryptographic algorithm for the protection of unclassified data, published in Federal Information Processing Standard (FIPS) 46. The DES, which was approved by the National Institute of Standards and Technology (NIST), is intended for public and government use.

Standardized encryption method used most on the Internet.

A standard method of encryptiong and decrypting data, developed by the U.S. National Bureau of Standards. DES is a block of cipher that works by a combination of transposition and substitution, and was developed after years of work at IBM, rigorously tested by the National Security Agency, and finally accepted as being free of any mathematical or statistical weaknesses. This meaning, that it is impossible to break the system using statistical frequency tables or to work the algorithm backwards using standard mathematical methods. DES has remained unbroken despite years of use; it completely randomizes the information so that it is impossible to determine the encryption key even if some of the original text is known. DES is used by the federal government and most banks and money-transfer systems to protect all sensitive computer information.

(upon which Kerberos is built) *A NIST-standard secret key cryptography method that uses a 56-bit key. DES is based on an IBM algorithm which was further developed by the U.S. National Security Agency. It uses the block cipher method which breaks the text into 64-bit blocks before encrypting them. There are several DES encryption modes. The most popular mode exclusive ORs each plaintext block with the previous encrypted block.

DES is the de facto symmetric encryption standard. IBM developed the core technology for DES in the 1970's.

A cryptographic algorithm designed to encrypt and decrypt data using a private key.

Block cipher that is widely used in commercial systems. It is a Federal FIPS standard so it is deemed acceptable by many financial institutions. However, its key length (56 bits) makes it vulnerable to attack by well funded adversaries.

A standard cryptographic algorithm developed by the U.S. National Bureau of Standards.

An encryption standard issued by the National Bureau of Standards.

An encryption standard developed by EBM and then tested and adopted by the National Bureau of Standards. Published in 1977, the DES standard has proven itself over nearly 20 years of use in both government and private sectors.

A standard security technique for scrambling information.

Encryption scheme, developed by IBM in the 1970s.

An encryption algorithm that uses a 56-bit key, and maps a 64-bit input block to a 64-bit output block. The key appears to be a 64-bit key, but one bit in each of the 8 bytes is used for odd parity, resulting in 56 bits of usable key.

A standardized encryption method widely used on the Internet.

DES is a very widely used symmetric encryption algorithm. DES is a block cipher.

(DES) A block cipher that encrypts data in 64-bit blocks. DES is a symmetric algorithm that uses the same algorithm and key for encryption and decryption. Developed in the early 1970s, DES is also known as the DEA (Data Encryption Algorithm) by ANSI and the DEA-1 by ISO.

A FIPS-approved cryptographic algorithm required by FIPS 140-1 and specified by FIPS PUBS 46-2. DES, which uses 56-bit keys, is a standard encryption and decryption algorithm that has been used successfully throughout the world for more than 20 years. See also FIPS PUBS 140-1. For detailed information, see http://www.itl.nist.gov/div897/pubs/fip46-2.htm.

A federal standard that was adopted in 1977 to protect unclassified communications and data. It was designed by IBM and modified by the National Security Agency*. It is now a widely used method of data encryption using a private key that was judged so difficult to break by the US government that it was restricted for exportation to other countries. There are 72,000,000,000,000,000 (72 quadrillion) or more possible encryption keys that can be used. For each given message, the key is chosen at random from among this enormous number of keys. Like other private key cryptographic methods, both the sender and the receiver must know and use the same private key.

Data Encryption Standard is an encryption block cipher defined and endorsed by the U.S. government in 1977 as an official standard (FIPS PUB 59). Developed by IBMÂ®, it has been extensively studied for over 15 years and is the most well known and widely used cryptosystem in the world. See also: Capstone, Clipper, RSA, Skipjack.

A widely used encryption algorithm endorsed as an official standard by the U.S. government in 1977, DES is a 64-bit block cipher that is used because of its speed. To address security concerns resulting from the relatively short (56 bit) key length, Triple DES (encrypting under three different DES keys in succession) is often employed.

The Data Encryption Standard (DES) is a cipher (a method for encrypting information) selected as an official Federal Information Processing Standard (FIPS) for the United States in 1976, and which has subsequently enjoyed widespread use internationally. The algorithm was initially controversial, with classified design elements, a relatively short key length, and suspicions about a National Security Agency (NSA) backdoor. DES consequently came under intense academic scrutiny, and motivated the modern understanding of block ciphers and their cryptanalysis.
