Message and types or writes it up in the form shown and hands it to the Enigma Now at receiving station U6Z, the radio operator receives the over-the-air The two letters, or perhaps appended one and prepended the other.Īfter the message indicator group, the encrypted text follows in 5 letter Prepend BN to the Kenngruppen value of UGZ. Sheet, and then pad it out with two random letters. Required the operator pick one of the Kenngruppen possibilities from the key The first group contains the Kenngruppen, or indicator. The army transmitted messages in 5 letter The top line indicates day 31, station C transmits to station U6Z, sent at 1500 U6Z DE C 1500 = 24 = WXC KCH = BNUGZ NIBLF MYMLL UFWCA SCSSN VHAZ = The operator then configures his machine: Let us also assume the reflector employed by this army unit is ‘B’. One of the daily Kenngruppen possibilities is UGZ. Plugboard settings are: AV BS CG DL FU HZ IN KM OW RX.Ring settings for each rotor, in order, are: B U L.Let’s suppose the key sheet dictates the following Machine consults his key sheet and configures his machine according to the daily Suppose a message needs to be transmitted. Rijmenants’ simulator manual, which is based upon a real-life example from Frode This example is based upon one found in Dirk We will now present a simplified scenario based on a procedure employed by theĪrmy ( Heer) after 1940. Numbers, space characters, place names, etc. On top of this,Įach branch of the military had its own conventions for encoding abbreviations, In general, the Kriegsmarine procedures were more elaborateĪnd involved not only key sheets but other auxiliary documents. These procedures varied by service branch and also changed during theĬourse of the war. The Wehrmacht had various elaborate procedures for transmitting and receiving Where order specifies the left-to-right order in the machine.
