The 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 the advancement of cryptography .
FIPS PUB 31 Guidelines for Automatic Data Processing Physical Security and Risk Management 1974; FIPS PUB 46-3 Data Encryption Standard 1999; FIPS PUB 73 Guidelines for Security of Computer Applications 1980; FIPS PUB 74 Guidelines for Implementing and Using the NBS Data Encryption Standard 1981; FIPS PUB 81 DES Modes of Operation 1980
This article details the various tables referenced in the Data Encryption Standard (DES) block cipher. All bits and bytes are arranged in big endian order in this document. That is, bit number 1 is always the most significant bit.
The Data Encryption Standard was a catalyst for further innovation in cryptography. Although now outdated, the idea behind DES was to create a government standard of encryption for unclassified or ...
The Data Encryption Standard (DES) and the Advanced Encryption Standard (AES) are block cipher designs that have been designated cryptography standards by the US government (though DES's designation was finally withdrawn after the AES was adopted). [44]
Data Encryption Standard (DES) – 64-bit block; FIPS 46-3, 1976; DEAL – an AES candidate derived from DES; DES-X – a variant of DES to increase the key size. FEAL; GDES – a DES variant designed to speed up encryption; Grand Cru – 128-bit block; Hierocrypt-3 – 128-bit block; CRYPTREC recommendation
Encrypt Mix Encrypt V2 (EME2) The P1619.3 Standard for Key Management Infrastructure for Cryptographic Protection of Stored Data defines a system for managing encryption data at rest security objects which includes architecture, namespaces, operations, messaging and transport. P1619 also standardized the key backup in the XML format.
In cryptography, the International Data Encryption Algorithm (IDEA), originally called Improved Proposed Encryption Standard (IPES), is a symmetric-key block cipher designed by James Massey of ETH Zurich and Xuejia Lai and was first described in 1991. The algorithm was intended as a replacement for the Data Encryption Standard (DES).
