During WWII, codes were used to securely communicate military and political information over radio as its use increased. Codes were used to encrypt information about ordinance, naval operations, important figures, and army units. The Allies were able to break German and Japanese codes by capturing code books, copying the German Enigma machine, and using skilled mathematicians, which was vital to helping the Allies win the war and shorten its length.
4. Why Use Codes?
As radio became the
principal medium for
communication during
WWII, there was an
increasing need to
ensure security of
political and military
information that was
exchanged via radio.
