What is ICCH?

The International Conference on Cryptologic History (ICCH) is a forum for the discussion of cryptologic history. Established in 2004 as 'Crypto Collectors', the group includes members located in many countries around the world. ICCH holds events both online and in-person, and also has an email list for general discussion.

Live presentations are held online every fortnight, covering topics including cipher machines/devices, as well as codes and codebreaking from the world's leading experts on cryptologic history. These are held via the video conferencing program Webex Meeting*. Once a year, ICCH meets at the Friedrichshafen HAM Radio Festival, in Germany for the annual Enigma Forum and flea market. Find out more about the Friedrichshafen event here.

Presentation:

The Ciphers of the Spies

Speakers:
Date & time (UTC/GMT):

Description:
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.
