The proliferation of computers and communications systems in the 1960s brought with
it a demand from the private sector for means to protect information in digital form and to
provide security services. Beginning with the work of Feistel at IBM in the early 1970s and
culminating in 1977 with the adoption as a U.S. Federal Information Processing Standard
for encrypting unclassified information, DES, the Data Encryption Standard, is the most
well-known cryptographic mechanism in history. It remains the standard means for securing electronic commerce for many financial institutions around the world.
