Elizebeth Smith Friedman and one example of a prohibition era encryption system
Abstract A short ciphertext message encrypted using a Prohibition era encryption system is examined. First published in David Kahn’s The Codebreakers, this example appears in two early reports written by Elizebeth Smith Friedman. Some obvious and some not so obvious errors are identified and corrected when possible. Friedman’s cryptanalysis of the ciphertext is given.
期刊介绍：
Cryptologia is the only scholarly journal in the world dealing with the history, the technology, and the effect of the most important form of intelligence in the world today - communications intelligence. It fosters the study of all aspects of cryptology -- technical as well as historical and cultural. The journal"s articles have broken many new paths in intelligence history. They have told for the first time how a special agency prepared information from codebreaking for President Roosevelt, have described the ciphers of Lewis Carroll, revealed details of Hermann Goering"s wiretapping agency, published memoirs - written for it -- of some World War II American codebreakers, disclosed how American codebreaking affected the structure of the United Nations.
