Definitions of data encryption standard:

Data Encryption Standard (DES) is a widely-used method of data encryption using a private (secret) 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. ...

In computer security, the National Institute of Standards and Technology (NIST) Data Encryption Standard, adopted by the US government as Federal Information Processing Standard (FIPS) Publication 46, which allows only hardware implementations of the data encryption algorithm.

A common 56-bit encryption standard, and the one used by RemoteScope. Abbreviated DES.

An algorithm used for encrypted which was the official algorithm of the United Sates Government. It was developed by IBM with assistance from the NSA. The algorithm is a sixteen round block cipher which uses a 64bit block and a 56bit key.

DES is a very widely used symmetric encryption algorithm. DES is a block cipher.
docs.sun.com/source/816-6294-10/glossary.htm
A symmetric key block cipher algorithm developed by IBM and adopted as a standard by the US National Institute of Standards and Technology in 1975. DES and its derivatives are still the most commonly used encryption algorithms.

A standard encryption technique that scrambles data into a code for transmission over a public network.

A popular standard encryption scheme.

A US Government Federal Information Processing Standard (FIPS 46) that specifies the Data Encryption Algorithm and states policy for using the algorithm to protect unclassified, sensitive data. Data Encryption Algorithm is a symmetric-key encryption algorithm. It uses 56 bit key.

The name of the Federal Information Processing Standard (FIPS), which describes the data encryption algorithm (DEA). DES and DEA are interchangeable. The DEA has a 64-bit block size and uses a 56-bit key during execution (8 parity bits a re stripped off from the full 64-bit key. The DEA is a symmetric cryptosystem. ...

US standard (1977) that uses a symmetric 56-bit key (the same key) for encryption and decryption. The official description of the standard is FIPS PUB 46. Top

The cryptographic algorithm adopted by ANSI that utilizes data encryption algorithm (DEA) as specified in ANSI X3.92-1981. Designated Agent: A Depository Institution or Network that, pursuant to an agreement with an Issuer, enters into Acquirer Agreements, Processor Agreement or additional Designated Agent Agreements on behalf of such Issuer.

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. DES is a type of encryption algorithm using a single key cipher. The encryption/decryption method is called symmetrical because the same key must be used to `lock' and `unlock' the data.

US Data Encryption Standard (DES), US FIPS Pub 46-2 and ANSI X3.92. DES is a symmetric encryption algorithm.

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. ...
