The American Black Chamber
''The American Black Chamber'' is a 1931 book by Herbert O. Yardley. The book describes the inner workings of the interwar American governmental cryptography organization called the Black Chamber. The cryptography historian David Kahn called the book "the most famous book on cryptology ever published." By describing the inner workings of the organization, the book created large interest and heightened public awareness of the United States's cryptographic abilities. In particular, the Japanese government became aware of the extent of experience that the American government had with cryptography and increased the strength of their own knowledge in cryptography in response. Reviewers suggested the book may have cost the United States significantly in the Pacific theater against Japan in World War II. The book was made into a film titled Rendezvous (1935 film) starring William Powell and Rosalind Russell Catherine Rosalind Russell (June 4, 1907November 28, 1976) was an American act ...

Black Chamber
The Black Chamber (1919–1929), also known as the Cipher Bureau, was the United States' first peacetime cryptanalytic organization, and a forerunner of the National Security Agency. The only prior codes and cypher organizations maintained by the US government had been some intermittent, and always abandoned, attempts by Armed Forces branches prior to World War I. History Headed by Herbert O. Yardley (1889–1958), the Black Chamber was founded in May 1919 following World War I. Yardley had commanded the U.S. Army cryptographic section of Military Intelligence (MI-8) during World War I. MI-8 was disbanded after the war. Jointly funded by the Army and the State Department, the Cipher Bureau was disguised as a New York City commercial code company; it actually produced and sold such codes for business use. Its true mission, however, was to break the communications (chiefly diplomatic) of other nations. During the Washington Naval Conference, it aided American negotiators by pro ...

History Of Cryptography
Cryptography, the use of codes and ciphers to protect secrets, began thousands of years ago. Until recent decades, it has been the story of what might be called classical cryptography — that is, of methods of encryption that use pen and paper, or perhaps simple mechanical aids. In the early 20th century, the invention of complex mechanical and electromechanical machines, such as the Enigma rotor machine, provided more sophisticated and efficient means of encryption; and the subsequent introduction of electronics and computing has allowed elaborate schemes of still greater complexity, most of which are entirely unsuited to pen and paper. The development of cryptography has been paralleled by the development of cryptanalysis — the "breaking" of codes and ciphers. The discovery and application, early on, of frequency analysis to the reading of encrypted communications has, on occasion, altered the course of history. Thus the Zimmermann Telegram triggered the United States' en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
