This material is made available for the sole purpose of studying and learning - misuse is strictly forbidden.DES was introduced in United States as official encryption standard in 1977 by NBS (National Bureau of Standards) after consulting with NSA (National Security Agency). NBS is nowadays known as NIST - National Institute of Standards and Technology). It was included in FIPS PUB 46-3 (NIST, 1999).
DES was designed by a series of IBM employees and contributors (the team who developed it was leaded by Walter Tuchman) based on the cipher invented by Horst Feistel. The background of Tuchman was mathematician and cryptographer. In addition to this, he was the director of IBM competency center within that period....
