The discovery and application, early on, of frequency analysis to the reading of encrypted communications has, on occasion, altered the course of history. Thus the Zimmermann Telegram triggered the United States' entry into World War I; and Allies reading of Nazi Germany 's ciphers shortened World War II, in some evaluations by as much as two ...

The Codebreakers is widely regarded as the best account of the history of cryptography up to its publication. William Crowell, the former deputy director of the National Security Agency, was quoted in Newsday magazine: "Before he (Kahn) came along, the best you could do was buy an explanatory book that usually was too technical and terribly dull."
1960–1964 Baran, Paul: One of two independent inventors of the concept of digital packet switching used in modern computer networking including the Internet. [9] [10] Published a series of briefings and papers about dividing information into "message blocks" and sending them over distributed networks (1960–1964). [11] [12] 1874 Baudot, Émile
In 1955, the AFSAM-7 was renamed TSEC/KL-7, following the new standard crypto nomenclature. It was the most widely used crypto machine in the US armed forces until the mid-1960s and was the first machine capable of supporting large networks that was considered secure against known plaintext attack. Some 25,000 machines were in use in the mid-1960s.
