洛仑兹密码机

Lorenz A.G制造的密码机
洛仑兹密码机(LorenzCipher),Lorenz SZ40/42 (德国,其盟军代号为“金枪鱼”),在线密码电传机LorenzSZ 42,大约在1943年由Lorenz A.G制造。英国人称其为“tunny”,用于德国战略级陆军司令部。SZ 40/SZ 42加密因为德国人的加密错误而被英国人破解,此后英国人一直使用电子COLOSSUS机器解读德国信号。

简介

The Lorenz SZ 40 and SZ 42(Schlüsselzusatz, meaning "cipher attachment") were German ciphermachines used during World War II for teleprinter circuits. Britishcodebreakers, who referred to encrypted German teleprinter traffic as"Fish", termed the machine and its traffic "Tunny". While thewell-known Enigma machine was generally used by field units, the Lorenz machinewas used for high-level communications which could support the heavy machine,teletypewriter and attendant fixed circuits. The machine itself measured 51 cm × 46 cm × 46 cm(20in × 18in × 18in), and served as an attachment to a standardLorenz teleprinter. The machines implemented a stream cipher.
