Rossignols
The Rossignols, a family of France, French cryptography, cryptographers and cryptanalysis, cryptanalysts, included Antoine Rossignol (1600–1682), Bonaventure Rossignol and Antoine-Bonaventure Rossignol. The family name means "nightingale" in French. As early as 1406, the word ''rossignol'' has served as the French term for "skeleton key" or for any tool which opens that which is locked. Antoine Rossignol In 1626, Henry II, Prince of Condé, Henri II of Bourbon, Prince de Condé laid siege to the Huguenot city of Réalmont. The besiegers intercepted a coded letter leaving the city. Rossignol, then a 26-year-old mathematician, had a local reputation for his interest in cryptography. He quickly broke the Huguenot cipher, revealing a plea to their allies for ammunition to replenish the city's almost exhausted supplies. The next day, the besiegers presented the clear text of the message to the commander of Réalmont, along with a demand for surrender. The Huguenots surrendered imme ...

Substitution Cipher
In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver deciphers the text by performing the inverse substitution process to extract the original message. Substitution ciphers can be compared with transposition ciphers. In a transposition cipher, the units of the plaintext are rearranged in a different and usually quite complex order, but the units themselves are left unchanged. By contrast, in a substitution cipher, the units of the plaintext are retained in the same sequence in the ciphertext, but the units themselves are altered. There are a number of different types of substitution cipher. If the cipher operates on single letters, it is termed a simple substitution cipher; a cipher that operates on larger groups of letters ...

Great Cipher
The Great Cipher ( French: ''Grand chiffre'') was a nomenclator cipher developed by the Rossignols, several generations of whom served the French monarchs as cryptographers. The Great Cipher was so named because of its excellence and because it was reputed to be unbreakable. Modified forms were in use by the French Peninsular army until the summer of 1811. After it fell out of current use, many documents in the French archives were unreadable until it was decoded. Historical background Antoine Rossignol's cryptographic skills became known in 1626, when an encrypted letter was taken from a messenger leaving the city of Réalmont, controlled by the Huguenots and surrounded by the French army. The letter stated that the Huguenots would not be able to hold on to the city for much longer, and by the end of the day, Rossignol had successfully deciphered it. The French returned the letter with the deciphered message and forced the Huguenots to surrender. He and his son, Bonaventure Ros ...

The Comprehensive History Of Secret Communication From Ancient Times To The Internet
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pron ...

The Baroque Cycle
''The Baroque Cycle'' is a series of novels by American writer Neal Stephenson. It was published in three volumes containing eight books in 2003 and 2004. The story follows the adventures of a sizable cast of characters living amidst some of the central events of the late 17th and early 18th centuries in Europe, Africa, Asia, and Central America. Despite featuring a literary treatment consistent with historical fiction, Stephenson has characterized the work as science fiction, because of the presence of some anomalous occurrences and the work's particular emphasis on themes relating to science and technology. The sciences of cryptology and numismatics feature heavily in the series, as they do in some of Stephenson's other works. Books The ''Baroque Cycle'' consists of several novels "lumped together into three volumes because it is more convenient from a publishing standpoint"; Stephenson felt calling the works a ''trilogy'' would be "bogus". Appearing in print in 2003 and 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cabinet Noir
In France, the ''cabinet noir'' ( French for " black room", also known as the "dark chamber" or "black chamber") was a government intelligence-gathering office, usually within a postal service, where correspondence between persons or entities was opened and read by government officials before being forwarded to its destination. However, this had to be done with some sophistication, as it was considered undesirable if the subjects of the practice knew about it, and important "that the black chamber not interrupt the smooth running of the postal service." This practice had been in vogue since the establishment of postal and telegraphy services, and was frequently used by the ministers of Louis XIII and Louis XIV; but it was not until the reign of Louis XV that a separate office for this purpose was created. This was called the ''cabinet du secret des postes'', or more popularly the ''cabinet noir''. Although declaimed against at the time of the French Revolution, it was used both b ...

Palace Of Versailles
The Palace of Versailles ( ; french: Château de Versailles ) is a former royal residence built by King Louis XIV located in Versailles, Yvelines, Versailles, about west of Paris, France. The palace is owned by the French Republic and since 1995 has been managed, under the direction of the Ministry of Culture (France), French Ministry of Culture, by the Public Establishment of the Palace, Museum and National Estate of Versailles. Some 15,000,000 people visit the palace, park, or gardens of Versailles every year, making it one of the most popular tourist attractions in the world. Louis XIII built a simple hunting lodge on the site of the Palace of Versailles in 1623 and replaced it with a small château in 1631–34. Louis XIV expanded the château into a palace in several phases from 1661 to 1715. It was a favorite residence for both kings, and in 1682, Louis XIV moved the seat of his court and government to Versailles, making the palace the ''de facto'' capital of France. This ...

Juvisy-sur-Orge
Juvisy-sur-Orge (, literally ''Juvisy on Orge'') is a commune in the Essonne department in Île-de-France in northern France. It is located 18 km south-east of Paris, a few kilometres south of Orly Airport. The site of the town has been occupied from ancient times; it is noted in Julius Caesar's book about the Gallic Wars. Centuries later, it became an important place under the French monarchy, as a royal hotel. It would also be used as a post relay, the first one on the road to Fontainebleau. It became a major road and railway junction in the 1840s after its railway station was built in 1840, and after 1893 was the first city surrounding Paris with a bridge crossing the river Seine. Most of the city was destroyed in April 1944 by an Allied bombing as the city was the only one surrounding Paris that had such a big railway station and had railway lines going to most of France's major cities. It was then rebuilt between 1945 and the 1970s. The city is today known for Gare d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
