What is Data Encryption Standard (DES)?

What does DES stand for?

The Records Encryption standard (DES) is a not unusual widespread for inFormation encryption and a shape of mystery key Cryptography (SKC), which uses only one key for encryption and Decryption. Public Key Cryptography (PKC) uses keys, i.E., one for encryption and one for decryption.

What Does Data Encryption Standard Mean?

In 1972, the National Bureau of Standards (NBS) approached the Institute for Computer Sciences and Technology (ICST) to plan an encryption set of rules to secure stored and transmitted information. The set of rules could be Publicly available, but its key might be pinnacle mystery.

The National Security Agency (NSA) assisted with the cryptographic set of rules assessment techniques, and in 1973, submission invites have been posted within the Federal Register. However, the submissions have been unaccepTable. In 1974, a 2d invitation was posted, which resulted in a submission from IBM. In 1975, technical specs have been posted for remarks inside the Federal Register, and analysis and evaLuation started. In 1977, NBS issued the Algorithm, i.E., DES, as Federal Information Processing Standards (FIPS) forty six.

Shortly thereafter, the U.S. Department of Defense (DoD) implemented DES. Specifications are mentioned in FIPS ebook forty six-three, FIPS 81, ANSI X3.92 and ANSI X3.106. For security motives, the U.S. Authorities has by no means legal exports of this Encryption Software program.

There are as a minimum sEventy two quadrillion DES key opportuNities. In 1993, NIST recertified DES, and the Advanced Encryption Standard (AES) have become its unofficial alternative.
