Giovanni Soro
Giovanni Soro (Venice, ? - 1544) was an Italian professional code-cracker.Lloyd, p. 14 ''Arguably the most successful Renaissance cryptanalyst was Giovanni Soro...'' He was the Renaissance's first outstanding cryptanalyst and the Western world's first great cryptanalyst.Kahn, p. 109 ''Giovanni Soro was perhaps the West's first great cryptanalyst''. Soro is known as the father of modern cryptography. Career Soro was employed in Venice in 1506 by the Council of Ten as cipher breaker-in-chief.Anzovin, item 3401 They were the first secret service specializing in codebreaking. Soro ran the cryptanalysis operation in secret as the cipher secretary. Soro's tasks included deciphering secret messages captured from the messenger spies of Venice's rivals. At the time, Venice was plagued by espionage and subterfuge. The Council of Ten had its own ciphers changed often so as to impede competitors such as François Viète, a French mathematician (father of modern algebraic notation). Successful ...

Venice
Venice ( ; it, Venezia ; vec, Venesia or ) is a city in northeastern Italy and the capital of the Veneto Regions of Italy, region. It is built on a group of 118 small islands that are separated by canals and linked by over 400 bridges. The islands are in the shallow Venetian Lagoon, an enclosed bay lying between the mouths of the Po River, Po and the Piave River, Piave rivers (more exactly between the Brenta (river), Brenta and the Sile (river), Sile). In 2020, around 258,685 people resided in greater Venice or the ''Comune di Venezia'', of whom around 55,000 live in the historical island city of Venice (''centro storico'') and the rest on the mainland (''terraferma''). Together with the cities of Padua, Italy, Padua and Treviso, Italy, Treviso, Venice is included in the Padua-Treviso-Venice Metropolitan Area (PATREVE), which is considered a statistical metropolitan area, with a total population of 2.6 million. The name is derived from the ancient Adri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
The Secret History Of Codes And Code-Breaking
''The'' () is a grammatical article in English, denoting persons or things already 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 pronouns 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 pronoun ''thee'') when followed by a v ...

Doge's Palace, Venice
The Doge's Palace ( it, Palazzo Ducale; vec, Pałaso Dogal) is a palace built in Venetian Gothic style, and one of the main landmarks of the city of Venice in northern Italy. The palace was the residence of the Doge of Venice, the supreme authority of the former Republic of Venice. It was built in 1340 and extended and modified in the following centuries. It became a museum in 1923 and is one of the 11 museums run by the Fondazione Musei Civici di Venezia. History In 810, Doge Agnello Participazio moved the seat of government from the island of Malamocco to the area of the present-day Rialto, when it was decided a ''palatium duci'' (Latin for "ducal palace") should be built. However, no trace remains of that 9th-century building as the palace was partially destroyed in the 10th century by a fire. The following reconstruction works were undertaken at the behest of Doge Sebastiano Ziani (1172–1178). A great reformer, he would drastically change the entire layout of the St. M ...

Pope Clement VII
Pope Clement VII ( la, Clemens VII; it, Clemente VII; born Giulio de' Medici; 26 May 1478 – 25 September 1534) was head of the Catholic Church and ruler of the Papal States from 19 November 1523 to his death on 25 September 1534. Deemed "the most unfortunate of the popes", Clement VII's reign was marked by a rapid succession of political, military, and religious struggles—many long in the making—which had far-reaching consequences for Christianity and world politics. Elected in 1523 at the end of the Italian Renaissance, Clement came to the papacy with a high reputation as a statesman. He had served with distinction as chief advisor to Pope Leo X (1513–1521), Pope Adrian VI (1522–1523), and commendably as gran maestro of Florence (1519–1523). Assuming leadership at a time of crisis, with the Protestant Reformation spreading; the Church nearing bankruptcy; and large, foreign armies invading Italy, Clement initially tried to unite Christendom by making peace among the ...

François Viète
François Viète, Seigneur de la Bigotière ( la, Franciscus Vieta; 1540 – 23 February 1603), commonly know by his mononym, Vieta, was a French mathematician whose work on new algebra was an important step towards modern algebra, due to its innovative use of letters as parameters in equations. He was a lawyer by trade, and served as a privy councillor to both Henry III and Henry IV of France. Biography Early life and education Viète was born at Fontenay-le-Comte in present-day Vendée. His grandfather was a merchant from La Rochelle. His father, Etienne Viète, was an attorney in Fontenay-le-Comte and a notary in Le Busseau. His mother was the aunt of Barnabé Brisson, a magistrate and the first president of parliament during the ascendancy of the Catholic League of France. Viète went to a Franciscan school and in 1558 studied law at Poitiers, graduating as a Bachelor of Laws in 1559. A year later, he began his career as an attorney in his native town. From the ...

Espionage
Espionage, spying, or intelligence gathering is the act of obtaining secret or confidential information (intelligence) from non-disclosed sources or divulging of the same without the permission of the holder of the information for a tangible benefit. A person who commits espionage is called an ''espionage agent'' or ''spy''. Any individual or spy ring (a cooperating group of spies), in the service of a government, company, criminal organization, or independent operation, can commit espionage. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law. Espionage is often part of an institutional effort by a government or commercial concern. However, the term tends to be associated with state spying on potential or actual enemies for military purposes. Spying involving corporations is known as industrial espionage.

Secret Service
A secret service is a government agency, intelligence agency, or the activities of a government agency, concerned with the gathering of intelligence data. The tasks and powers of a secret service can vary greatly from one country to another. For instance, a country may establish a secret service which has some policing powers (such as surveillance) but not others. The powers and duties of a government organization may be partly secret and partly not. The organization may be said to operate openly at home and secretly abroad, or vice versa. Secret police and intelligence agencies can usually be considered secret services. Various states and regimes, at different times and places, established bodies that could be described as a secret service or secret police – for example, the ''agentes in rebus'' of the late Roman Empire were sometimes defined as such. In modern times, the French police officer Joseph Fouché is sometimes regarded as the primary pioneer within secret intellig ...
