Description
The Special Operations Executive (SOE), a British WW2 group infiltrating Reich-dominated Europe, had during the War's early and middle years a continuing problem in certain parts of France. They would train new agents, drop them into French territory, note their contact with a local agent... and they were lost, presumed captured or killed. Two things needed to happen fast: first, a new network had to be built so fresh agents would not be compromised by the older, discovered network. And second, a code generation method must be implemented that did not give a field agent knowledge of how other field agents generated similar messages into encrypted form (knowledge that could be extracted by torture). The answer to the second problem was called a "one time pad", a method still in use today and which had life-saving results almost immediately in the Allied war effort.
Description
A World War II cryptographer chronicles his career in the Special Operations Executive, discussing his replacement of outmoded codes with one-time silk-printed codes.
