Presentation:

A Few Gems from Elizebeth Smith Friedman’s Papers at the Marshall Library

Speaker(s):
Date & time (UTC/GMT):
May 1, 2022 5:00 PM
Description:

Last summer I spent two days reading through Elizebeth Smith Friedman’s papers at the George C. Marshall Library in Lexington, VA. As a result, I have begun compiling a collection of complete crypto systems solved by Elizebeth Friedman. These examples are perfect for those who have read Jason Fagone’s excellent biography but want a bit more hands-on work with the plaintext and ciphertext associated with the rumrunning smugglers of the Prohibition era. I will share examples of crypto systems solved by Elizebeth Friedman, point out a correction to one of the examples from David Kahn’s Codebreakers, and end with some fun ciphers Elizebeth and William Friedman used to challenge their dinner guests on one November evening in 1938.
