t. e. The Enigma machine was used commercially from the early 1920s and was adopted by the militaries and governments of various countries—most famously, Nazi Germany. Cryptanalysis of the Enigma ciphering system enabled the western Allies in World War II to read substantial amounts of Morse-coded radio communications of the Axis powers that ...
The Enigma machine is a cipher device developed and used in the early- to mid-20th century to protect commercial, diplomatic, and military communication. It was employed extensively by Nazi Germany during World War II, in all branches of the German military. The Enigma machine was considered so secure that it was used to encipher the most top ...
Three rotors in sequence. The right side of a rotor, showing the pin electrical contacts. The Roman numeral V identifies the wiring of the rotor. The left side of an Enigma rotor, showing the flat (plate) electrical contacts. A single turnover notch is visible on the left edge of the rotor.
Colossus was a set of computers developed by British codebreakers in the years 1943–1945 [ 1 ] to help in the cryptanalysis of the Lorenz cipher. Colossus used thermionic valves (vacuum tubes) to perform Boolean and counting operations. Colossus is thus regarded [ 2 ] as the world's first programmable, electronic, digital computer, although ...

Triple DES. In cryptography, Triple DES (3DES or TDES), officially the Triple Data Encryption Algorithm (TDEA or Triple DEA), is a symmetric-key block cipher, which applies the DES cipher algorithm three times to each data block. The 56-bit key of the Data Encryption Standard (DES) is no longer considered adequate in the face of modern ...
Alan Mathison Turing OBE FRS (/ ˈtjʊərɪŋ /; 23 June 1912 – 7 June 1954) was an English mathematician, computer scientist, logician, cryptanalyst, philosopher and theoretical biologist. [ 5 ] He was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation ...
11516745. Dewey Decimal. 510.92. LC Class. QA29.T8H63. Alan Turing: The Enigma (1983) is a biography of the British mathematician, codebreaker, and early computer scientist, Alan Turing (1912–1954) by Andrew Hodges. The book covers Alan Turing's life and work. The 2014 film The Imitation Game is loosely based on the book, with dramatization.
