Radio Wave and Great War🐱💦 - 令和義塾🛡中高生・高卒生・教員・留学志望者のための学習塾

The mixed blessings of radio - ease of communication and ease of interception - were brought into sharp focus at the outbreak of the First World War. All sides were keen to exploit the power of radio, but were also unsure of how to guarantee security. Together, the advent of radio and the Great War intensified the need for effective encryption. The hope was that there would be a breakthrough, some new cipher that would reestablish secrecy for military commanders.

However, between 1914 and 1918 there was to be no great discovery, merely a catalogue of cryptograpfic failures. Codemakers conjured up several new ciphers, but one by one they were broken.
