Norwegian Enigma

The reels of the captured Enigmas were rewired by the Norwegians

The Norwegian Enigma are Enigma machines newly wired by Norway .

history

In 1945, immediately after the end of the Second World War , the Norwegian intelligence service , then called Overvåkingspolitiet ("surveillance police ") , used some Enigma rotor key machines captured by the German Wehrmacht for their own encryption purposes . The Norwegians rewired the rotating rollers (I to V) and also the reversing roller (VHF) . The wiring of the entry roller (ETW), however, as well as the transfer notches of the rollers were left unchanged. To distinguish them from the regularly wired Enigma machines , these Enigma models modified in this way are referred to as "Norenigma" (and also as Norway Enigma ).

Roller wiring

The wiring of the individual rollers of the Norenigma is given in the following table:
