Presentation:

The Ciphers of the Spies

Speaker(s):
Date & time (UTC/GMT):
April 16, 2023 5:00 PM
Description:

The history of espionage has been inextricably linked with encryption technology for centuries in a fascinating way. The German Chancellor's spy Günter Guillaume was unmasked in 1974 because West German codebreakers were able to solve encrypted GDR radio messages. Deciphered secret messages were also the undoing of nuclear spy Klaus Fuchs in the 1940s and the legendary Mata Hari in the 1920s. Other secret agents, however, got away with it because their encryption methods proved to be secure. Klaus and Elonka will go over these, and many other cipher-related spy stories throughout history.
