The Machines That Sparked the Beginning of the Computer Age

jjp9999 writes "A war of spies and electromechanical machines that took place beneath the wires during World War II not only played a crucial role in the Allies' victory, but also helped spark the beginning of the computer age. Among the devices was the Enigma, a cipher capable of producing 150,000,000,000,000,000,000 possible code combinations, and a hulking machine, the Colossus, the first programmable electronic computer, capable of decoding the Enigma."

  2. American Crypto better than Enigma by cold+fjord · · Score: 5, Informative

    In these discussions it is common to overlook Sigaba, the American encryption machine that was significantly more secure than Enigma.

    SIGABA was similar to the Enigma in basic theory, in that it used a series of rotors to encipher every character of the plaintext into a different character of ciphertext. Unlike Enigma's three rotors however, the SIGABA included fifteen, and did not use a reflecting rotor.

    Electronic Cipher Machine (ECM) Mark II

    The ECM Mark II based cryptographic system is not known to have ever been broken by an enemy and was secure throughout WW II. The system was retired by the U.S. Navy in 1959 because it was too slow to meet the demands of modern naval communications. Axis powers (primarily Germany) did however periodically break the lower grade systems used by Allied forces. Early in the war (notably during the convoy battle of the Atlantic and the North Africa campaign) the breaking of Allied systems contributed to Axis success.

    Cryptanalysis of the SIGABA --- 3.4 Stepping Maze

    While other rotor-based cryptosystems tended to rotate their rotors as an odometer (with the last rotor moving one position per letter, and each other rotor moving one position when the rotor after it completes a full cycle), the SIGABA introduces
    an innovative concept. The movement of its cipher rotors depend on the two other rotor banks, collectively known as the stepping maze. The output of the stepping maze is not seen directly, but rather controls the movements of the cipher rotors. Thus, the SIGABA uses a hidden cryptosystem within another cryptosystem.

    The Germans that beat their heads against it referred to it as, "The big machine".

His greatest achievement was the world's first functional program-controlled Turing-complete computer, the Z3, which became operational in May 1941. He received the Werner-von-Siemens-Ring in 1964 for the Z3.[1] Much of his early work was financed by his family and commerce, but after 1939 he was given resources by the Nazi German Government.[2]
    Zuse's S2 computing machine is considered to be the first process-controlled computer. In 1946, he designed the first high-level programming language, Plankalkül.[3] Zuse founded one of the earliest computer businesses on 1 April 1941 (Zuse Ingenieurbüro und Apparatebau).[4] This company built the Z4, which became the world's first commercial computer."

    A few bits of truth floating in a frothing stew of errors.

    As noted elsewhere, COLOSSUS was not used to break Enigma; it was designed to break the cipher of the Lorenz machine (Geheimschreiber). If the Allies had needed COLOSSUS to break Enigma, the war would have been much longer and bloodier. COLOSSUS was not even operational until February 1944. The Allies had re-broken Enigma in early 1940, by hand methods. They read the main Luftwaffe key (RED) from then until the end of the war. They read the main navy key (HYDRA) from mid-1941 on. In 1942, the Germans adopted a special high-quality key for U-boats only (TRITON) which was not broken for 10 months (during which the Battle of the Atlantic was nearly lost). TRITON was finally broken by Turing himself.

    Use of the Enigma machine did not "spread through the German military". Enigma was adopted as the standard cipher machine for all branches of the German armed forces by 1929.

    The "Turing Machine" was not "one of the earliest modern computers", it is a theoretical model of a computing device.

    The Germans did not "[strengthen] their system by changing the cipher every day.” They had more than one "cipher" - more precisely, each branch or sub-branch of service had its own daily settings for the Enigma (its "key"). There were about 50 Enigma keys in use by the end of the war.

    ULTRA was the code term for any intelligence from decrypted enemy signals. Enigma signals were not decrypted with COLOSSUS - nor with the electromechanical "bombes" used to crack Enigma. The function of the bombes was to find the settings for a key. The key-finding process tested settings against a "crib": ciphertext for which the cleartext was known or guessable. The testing went on until a setting produced the expected cleartext. Then all messages on that key could be decoded using a copy of the Enigma.
