DES Is Dead! Long Live ????

Abstract

Abstract The Data Encryption Standard (DES) is an encryption cipher defined and endorsed by the U.S. government in 1977 as an official federal standard. Details about DES can be found in the FIPS (Federal Information Processing Standards) publication (FIPS 46-2). DES was originally developed at IBM under the auspices of the National Security Agency in what was known as Project Lucifer. DES has been extensively studied since its inception and is both the most well- known and most widely used cryptosystem in the world. DES was intended to provide strong encryption for the government's sensitive but unclassified information.
