Sep 20, 2023 · This article talks about the Data Encryption Standard (DES), a historic encryption algorithm known for its 56-bit key length. We explore its operation, key transformation, and encryption process, shedding light on its role in data security and its vulnerabilities in today’s context.
Developed in the early 1970s at IBM and based on an earlier design by Horst Feistel, the algorithm was submitted to the National Bureau of Standards (NBS) following the agency's invitation to propose a candidate for the protection of sensitive, unclassified electronic government data.
The Data Encryption Standard (DES) is a symmetric-key block cipher published by the National Institute of Standards and Technology (NIST). DES is an implementation of a Feistel Cipher. It uses 16 round Feistel structure.
Feb 9, 2024 · The DES (Data Encryption Standard) algorithm is a symmetric-key block cipher created in the early 1970s by an IBM team and adopted by the National Institute of Standards and Technology (NIST). The algorithm takes the plain text in 64-bit blocks and converts them into ciphertext using 48-bit keys.
Data Encryption Standard (DES) is an obsolete encryption algorithm. Find out how it worked, why it's no longer safe and where it's still being used.
DES, or Data Encryption Standard, is a symmetric-key algorithm used to encrypt and protect data transmission in cybersecurity. It was one of the first encryption standards used widely in the industry, but has since been replaced by stronger algorithms due to its vulnerability to brute-force attacks.
In 1977 DES was adopted as a government standard and it was only expected that DES would be used as a standard for 10-15 years, however it was a standard until 1999 where developing of its replacement the Advanced Encryption Standard (AES) had begun.
Apr 16, 1997 · DES is short for Data Encryption Standard, a popular symmetric-key encryption method developed in 1975 and standardized by ANSI in 1981 as ANSI X.3.92. DES uses a 56-bit key and the block cipher method, which breaks text into 64-bit blocks and then encrypts them.
Data Encryption Standard (DES), an early data encryption standard endorsed by the U.S. National Bureau of Standards (NBS; now the National Institute of Standards and Technology). It was phased out at the start of the 21st century by a more secure encryption standard, known as the Advanced.

The Data Encryption Standard (DES) [ 31] has been around for more than 25 years. During this time the standard was revised three times: as FIPS-46-1 in 1988, as FIPS-46-2 in 1993 and as FIPS-46-3 in 1999. DES was an outcome of a call for primitives in 1974, which did not result in many serious candidates except for a predecessor of DES, Lucifer
