World War I cryptography
With the rise of easily intercepted wireless telegraphy, codes and ciphers were used extensively in World War I. The decoding by British Naval intelligence of the Zimmermann telegram helped bring the United States into the war.
Trench codes were used by field armies of most of the combatants (Americans, British, French, German) in World War I.
The most commonly used codes were simple substitution ciphers. More important messages generally used mathematical encryption for extra security. The use of these codes required the distribution of codebooks to military personnel, which proved to be a security liability since these books could be stolen by enemy forces.
British decrypting was carried out in Room 40 by the Royal Navy and in MI1 by British Military (Army) Intelligence.
The French Army employed Georges Painvin, and Étienne Bazeries who came out of retirement, on German ciphers. Due to their prewar activities, the French were more prepared than any other nation involved in the war to decode German radiograms. At the beginning of the war, France had eight intercept stations: Maubeuge, Verdun, Toul, Epinal, Belfort, Lille, Rheims, and Besançon. During the war, they set up many more stations, including one in the Eiffel Tower. According to Colonel Cartier of the War Ministry, France intercepted over 100,000,000 words from German radiograms during the course of the war.
The Imperial German Army and the Austro-Hungarian Army intercepted Russian radio communications traffic, although German success at the Battle of Tannenberg (1914) was due to interception of messages between the Imperial Russian Army commanders in cleartext.
The German Abhorchdienst, a code-breaking bureau composed mainly of mathematicians, was established in 1916.
The Germans had specific regulations regarding which kinds of codes and ciphers could be used under given circumstances. Within three kilometers of the front lines, known as the danger zone, all communications were required to be in a code known as the three-number code. This was the only code or cipher permitted. Behind this danger zone, another code known as the three-letter code was allowed to be used. Communications between divisions, corps, and army headquarters were done with the ADFGVX cipher.
