Data Encryption Standard - Wikipedia
WEBThe Data Encryption Standard (DES / ˌ d iː ˌ iː ˈ ɛ s, d ɛ z /) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure for modern applications, it has been highly influential in …
Data Encryption Standard: Concept and Modes of Operations
WEBMay 24, 2024 · The data encryption standard, created by the United States National Institute of Standards and Technology in the 1970s, is a block cypher system commonly used for securing data [ 1 ]. It takes a 64-bit plaintext at the encryption site and develops a 64-bit cyphertext.

WEBSep 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. What is DES?
What is Data Encryption Standard? Definition from TechTarget
WEBData Encryption Standard (DES) is an outdated symmetric key method of data encryption. It was adopted in 1977 for government agencies to protect sensitive data and was officially retired in 2005. IBM researchers originally designed the standard in the early 1970s.
Data encryption standard (DES) | SpringerLink
WEBThe Data Encryption Standard, as specified in FIPS Publication 46-3 [ 31 ], is a block cipher operating on 64-bit data blocks. The encryption transformation depends on a 56-bit secret key and consists of sixteen Feistel iterations surrounded by two permutation layers: an initial bit permutation IP at the input, and its inverse IP -1 at the output.

Data Encryption Standard - an overview | ScienceDirect Topics
WEBThe Data Encryption Standard (DES) is a block cipher and was introduced by NIST in 1974. It has a 56-bit key size that makes it vulnerable to brute force attacks with current computing power, so while DES is still in use and is part of the TLS cipher suite, the DES cipher is not recommended for use new in designs.
Data Encryption Standard - an overview | ScienceDirect Topics
WEBThe data encryption standard (DES) defined by US NIST performs encryption in hardware thereby speeding up the encryption and decryption operation. Additional features of DES are: 1. DES is a block cipher and works on a fixed-size block of data. The message is segmented into blocks of plaintext, each comprising 64 bits.
