Japanese M-1 Cipher Machine
The Japanese M-1 cipher machine was a mechanical device the Japanese used for performing cryptography sometime during the 1930s. More specifically it was used by naval attaches. The US called it the ''ORANGE machine''. Cryptographically it is similar to the Red cipher; it was broken by Agnes Driscoll Agnes Meyer Driscoll (July 24, 1889 – September 16, 1971), known as "Miss Aggie" or "Madame X'", was an American cryptanalyst during both World War I and World War II and was known as “the first lady of naval cryptology."

Red (cipher Machine)
In the history of cryptography, or , codenamed Red by the United States, was a diplomatic cryptographic machine used by the Japanese Foreign Office before and during World War II. A relatively simple device, it was quickly broken by western cryptographers. The Red cipher was succeeded by the which used some of the same principles. Parallel usage of the two systems assisted in the breaking of the Purple system. The Red cipher should not be confused with the Red naval code, which was used by the Imperial Japanese Navy between the wars. The latter was a codebook system, not a cipher. Operation The Red machine encrypted and decrypted texts written in Latin characters (alphabetic only) for transmission through the cable services. These services charged a lower rate for texts that could be pronounced than for random strings of characters; therefore the machine produced telegraph code by enciphering the vowels separately from the consonants, so that the text remained a series of syll ...

Agnes Meyer Driscoll
Agnes Meyer Driscoll (July 24, 1889 – September 16, 1971), known as "Miss Aggie" or "Madame X'", was an American cryptanalyst during both World War I and World War II and was known as “the first lady of naval cryptology." Early years Born in Geneseo, Illinois, in 1889, Driscoll moved with her family to Westerville, Ohio, in 1895 where her father, Gustav Meyer, had taken a job teaching music at Otterbein College. In 1909, he donated the family home to the Anti-Saloon League, which had recently moved its headquarters to Westerville. The home was later donated to the Westerville Public Library and is now home to the Anti-Saloon League Museum and the Westerville Local History Center. Education Driscoll attended Otterbein College from 1907 to 1909. In 1911, she received a Bachelor of Arts degree from the Ohio State University, having majored in mathematics and physics and studied foreign languages, statistics and music. She was fluent in English, French, German, Latin and Japanese. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
