Timeline 1900-1970 AD 1913 the wheel cipher gets re-invented as a strip 1917 William Frederick Friedman starts working as a cryptoanalyst at Riverbank Laboratories, which also works for the U.S. Government. Later he creates a school for military cryptoanalysis - an AT&T-employee, Gilbert S. Vernam, invents a polyalphabetic cipher machine that works with random-keys 1918 the Germans start using the ADFGVX-system, that later gets later by the French Georges Painvin - Arthur Scherbius patents a ciphering machine and tries to sell it to the German Military, but is rejected 1919 Hugo Alexander Koch invents a rotor cipher machine 1921 the Hebern Electric Code, a company producing electro-mechanical cipher machines, is founded 1923 Arthur Scherbius founds an enterprise to construct and finally sell his Enigma machine for the German Military late 1920's/30's more and more it is criminals who use cryptology for their purposes (e.g. for smuggling). Elizabeth Smith Friedman deciphers the codes of rum-smugglers during prohibition regularly 1929 Lester S. Hill publishes his book Cryptography in an Algebraic Alphabet, which contains enciphered parts 1933-1945 the Germans make the Enigma machine its cryptographic main-tool, which is broken by the Poles Marian Rejewski, Gordon Welchman and Alan Turing's team at Bletchley Park in England in 1939 1937 the Japanese invent their so called Purple machine with the help of Herbert O. Yardley. The machine works with telephone stepping relays. It is broken by a team of William Frederick Friedman. As the Japanese were unable to break the US codes, they imagined their own codes to be unbreakable as well - and were not careful enough. 1930's the Sigaba machine is invented in the USA, either by W.F. Friedman or his colleague Frank Rowlett - at the same time the British develop the Typex machine, similar to the German Enigma machine 1943 Colossus, a code breaking computer is put into action at Bletchley Park 1943-1980 the cryptographic Venona Project, done by the NSA, is taking place for a longer period than any other program of that type 1948 Shannon, one of the first modern cryptographers bringing mathematics into cryptography, publishes his book A Communications Theory of Secrecy Systems 1960's the Communications-Electronics Security Group (= CESG) is founded as a section of Government Communications Headquarters (= GCHQ) late 1960's the IBM Watson Research Lab develops the Lucifer cipher 1969 James Ellis develops a system of separate public-keys and private-keys

Abstract What we seem to fear most is to get into a status of insecurity - given that the definitions of the word security vary extremely. Thus methods of securing ideas, people, things or data increase their popularity and necessity tremendously. One of them is cryptography - as well as the prohibition/restriction of cryptography. Questions whether cryptography is absolutely inevitable or on the contrary supports certain criminals more than the ordinary internet-user, are arising. And as the last developments in international and national law showed, Northern governments are changing opinion about that, due to economic tasks. Business needs cryptography. Still, the use of cryptography is no recent invention. Already the first steps in writing or even in human communication itself meant developing codes for keeping secrets at the same time as providing information. This site gives a timeline for the history of cryptography, provides an introduction into the most important terms of tools and devices connected to that topic, and finally tries to interpret necessities for and ideas against cryptography or in other words leads through the current discussions concerning democracy and governmental fears and doubts regarding the security of data-transmission.

MIT The MIT (Massachusetts Institute of Technology) is a privately controlled coeducational institution of higher learning famous for its scientific and technological training and research. It was chartered by the state of Massachusetts in 1861 and became a land-grant college in 1863. During the 1930s and 1940s the institute evolved from a well-regarded technical school into an internationally known center for scientific and technical research. In the days of the Great Depression, its faculty established prominent research centers in a number of fields, most notably analog computing (led by Vannevar Bush) and aeronautics (led by Charles Stark Draper). During World War II, MIT administered the Radiation Laboratory, which became the nation's leading center for radar research and development, as well as other military laboratories. After the war, MIT continued to maintain strong ties with military and corporate patrons, who supported basic and applied research in the physical sciences, computing, aerospace, and engineering. MIT has numerous research centers and laboratories. Among its facilities are a nuclear reactor, a computation center, geophysical and astrophysical observatories, a linear accelerator, a space research center, supersonic wind tunnels, an artificial intelligence laboratory, a center for cognitive science, and an international studies center. MIT's library system is extensive and includes a number of specialized libraries; there are also several museums.

Enochian alphabet Also "Angelic" language. Archaic language alphabet composed of 21 letters, discovered by John Dee and his partner Edward Kelley. It has its own grammar and syntax, but only a small sample of it has ever been translated to English.
