Sigcum (Eigenschreibweise: SIGCUM), auch bezeichnet als Converter M-228, war eine während des Zweiten Weltkriegs entwickelte und kurzzeitig eingesetzte amerikanische Rotor-Schlüsselmaschine. Aufgrund von durch die Amerikaner selbst erkannten kryptographischen Schwächen wurde sie nach kurzer Zeit abgelöst. (de) SIGCUM, also known as Converter M-228, was a rotor cipher machine used to encrypt teleprinter traffic by the United States Army. Hastily designed by William Friedman and Frank Rowlett, the system was put into service in January 1943 before any rigorous analysis of its security had taken place. SIGCUM was subsequently discovered to be insecure by Rowlett, and was immediately withdrawn from service. The machine was redesigned to improve its security, reintroduced into service by April 1943, and remained in use until the 1960s. (en) |
