Chaocipher
The Chaocipher is a cipher method invented by John Francis Byrne in 1918 and described in his 1953 autobiographical ''Silent Years''. He believed Chaocipher was simple, yet unbreakable. Byrne stated that the machine he used to encipher his messages could be fitted into a cigar box. He offered cash rewards for anyone who could solve it. Byrne tried unsuccessfully to interest the US Signal Corp and Navy in his system. Although numerous students of classical cryptanalysis attempted to solve the challenge messages over the years, none succeeded. For 90 years, the Chaocipher algorithm was a closely guarded secret known only to a handful of persons. In May 2010 Byrne's daughter-in-law, Patricia Byrne, donated all Chaocipher-related papers and artifacts to the National Cryptologic Museum in Ft. Meade, Maryland, USA. This led to the disclosure of the Chaocipher algorithm. Design In Byrne's embodiment of Chaocipher, the system consists of two disks, referred to as the left and right ...

Patricia Neway
Patricia Neway (September 30, 1919 – January 24, 2012) was an American operatic soprano and musical theatre actress who had an active international career during the mid-1940s through the 1970s. One of the few performers of her day to enjoy equal success on both the opera and musical theatre stages, she was a regular performer on both Broadway and at the New York City Opera during the 1950s and 1960s. Critic Emily Langer of ''The Washington Post'' wrote that, "Neway was a rare type of singer — one with the classical training and raw vocal strength to meet the demands of opera as well as the acting talent and appeal required to succeed in musical theater." She is particularly remembered for creating roles in the world premieres of several contemporary American operas, most notably Magda Sorel in Gian Carlo Menotti's ''The Consul''. On Broadway she won a Tony Award for her portrayal of the Mother Abbess in the original production of Rodgers and Hammerstein's ''The Sound of Music'' ...

Autokey Cipher
An autokey cipher (also known as the autoclave cipher) is a cipher that incorporates the message (the plaintext) into the key. The key is generated from the message in some automated fashion, sometimes by selecting certain letters from the text or, more commonly, by adding a short ''primer key'' to the front of the message. There are two forms of autokey cipher: ''key-autokey'' and ''text-autokey'' ciphers. A key-autokey cipher uses previous members of the keystream to determine the next element in the keystream. A text-autokey uses the previous message text to determine the next element in the keystream. In modern cryptography, self-synchronising stream ciphers are autokey ciphers. History This cipher was invented in 1586 by Blaise de Vigenère with a reciprocal table of ten alphabets. Vigenère's version used an agreed-upon letter of the alphabet as a primer, making the key by writing down that letter and then the rest of the message. More popular autokeys use a tabula recta, ...

Cipher
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is ''encipherment''. To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code", as they are both a set of steps that encrypt a message; however, the concepts are distinct in cryptography, especially classical cryptography. Codes generally substitute different length strings of characters in the output, while ciphers generally substitute the same number of characters as are input. There are exceptions and some cipher systems may use slightly more, or fewer, characters when output versus the number that were input. Codes operated by substituting according to a large codebook which linked a random string of characters or numbers to a word or phrase. For example, "UQJHSE" could be the code for "Proceed to the following ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cigar Box
A cigar box is a box container for cigar packaging. Traditionally cigar boxes have been made of wood, cardboard or paper. Spanish cedar has been described as the "best" kind of wood for cigar boxes because of its beautiful grain, fine texture, and pleasant odor and ability to keep out insects. Eucalyptus and yellow poplar have been popular substitutes that were sometimes stained and scented to resemble it. Other typical woods for cigar boxes include mahogany, elm, and white oak; less-popular are basswood, Circassian walnut, and rosewood. There are several types of cigar boxes, differing both in construction and purpose. The following are common boxes: *Cabinet selection, slid-lid or hinged lid, typically storing 25 or 50 cigars *8-9-8, round-sided box with three layers, counting 8, 9 and 8 cigars respectively. *Flat top or 13-topper, two layers with 12 on bottom and 13 on top *Boxes of box-pressed cigars, stored two layers with same number of cigars. Cigar boxes, labels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Cryptologic Museum
The National Cryptologic Museum (NCM) is an American museum of cryptologic history that is affiliated with the National Security Agency (NSA). The first public museum in the U.S. Intelligence Community, NCM is located in the former Colony Seven Motel, just two blocks from the NSA headquarters at Fort George G. Meade in Maryland. The motel was purchased, creating a buffer zone between the high security main buildings of the NSA and an adjacent highway. The museum opened to the public on December 16, 1993, and now hosts about 50,000 visitors annually from all over the world. The NCM is open Tuesday through Saturday, 10am-4pm (hours are extended Wednesdays to 7pm). It is closed on Sundays, Mondays. and all federal holidays, and operates on NSA's emergency/weather closure schedule (i.e. if NSA is closed, the museum is closed as well). The NCM includes a gift store whose operational hours coordinate with the museum's operational schedule (i.e., if the museum is closed altogether, o ...

Locating The Letter "A" On The Right (plaintext) Chaocipher Wheel
In geography, location or place are used to denote a region (point, line, or area) on Earth's surface or elsewhere. The term ''location'' generally implies a higher degree of certainty than ''place'', the latter often indicating an entity with an ambiguous boundary, relying more on human or social attributes of place identity and sense of place than on geometry. Types Locality A locality, settlement, or populated place is likely to have a well-defined name but a boundary that is not well defined varies by context. London, for instance, has a legal boundary, but this is unlikely to completely match with general usage. An area within a town, such as Covent Garden in London, also almost always has some ambiguity as to its extent. In geography, location is considered to be more precise than "place". Relative location A relative location, or situation, is described as a displacement from another site. An example is "3 miles northwest of Seattle". Absolute location An absolute locatio ...

Permuting Chaocipher Left Wheel
In mathematics, a permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements. The word "permutation" also refers to the act or process of changing the linear order of an ordered set. Permutations differ from combinations, which are selections of some members of a set regardless of order. For example, written as tuples, there are six permutations of the set , namely (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 2, 1). These are all the possible orderings of this three-element set. Anagrams of words whose letters are different are also permutations: the letters are already ordered in the original word, and the anagram is a reordering of the letters. The study of permutations of finite sets is an important topic in the fields of combinatorics and group theory. Permutations are used in almost every branch of mathematics, and in many other fields of scien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Cryptogram Association
The American Cryptogram Association (ACA) is an American non-profit organization devoted to the hobby of cryptography, with an emphasis on types of codes, ciphers, and cryptograms that can be solved either with pencil and paper, or with computers, but not computer-only systems. History The ACA was formed on September 1, 1930. Initially the primary interest was in monoalphabetic substitution ciphers (also known as "single alphabet" or "Aristocrat" puzzles), but this has since extended to dozens of different systems, such as Playfair, autokey, transposition, and Vigenère ciphers. Since some of its members had belonged to the “National Puzzlers' League”, some of the NPL terminology ("nom," "Krewe," etc.) is also used in the ACA.
