Auguste Kerckhoffs
Auguste Kerckhoffs (19 January 1835 – 9 August 1903) was a Dutch linguist and cryptographer in the late 19th century. Biography Kerckhoffs was born in Nuth, the Netherlands, as Jean Guillaume Auguste Victor François Hubert Kerckhoffs, son of Jean Guillaume Kerckhoffs, mayor of the village of Nuth, and Jeanette Elisabeth Lintjens. Kerckhoffs studied at the University of Liège. After a period of teaching in schools in the Netherlands and France, he became a professor of German language at the École des Hautes Études Commerciales (Paris) and the École Arago. Principles He is best known today for his two-part paper published in 1883 in ''Le Journal des Sciences Militaires'' (''Journal of Military Science'') entitled ''La Cryptographie Militaire'' (''Military Cryptography''). These articles surveyed the then state-of-the-art in military cryptography, and made a plea for considerable improvements in French practice. They also included many pieces of practical advice ...

Kerckhoffs's Principle
Kerckhoffs's principle (also called Kerckhoffs's desideratum, assumption, axiom, doctrine or law) of cryptography was stated by the Dutch cryptographer Auguste Kerckhoffs in the 19th century. The principle holds that a cryptosystem should be secure, even if everything about the system, except the key, is public knowledge. This concept is widely embraced by cryptographers, in contrast to security through obscurity, which is not. Kerckhoffs's principle was phrased by the American mathematician Claude Shannon as "the enemy knows the system", i.e., "one ought to design systems under the assumption that the enemy will immediately gain full familiarity with them". In that form, it is called Shannon's maxim. Another formulation by American researcher and professor Steven M. Bellovin is: In other words—design your system assuming that your opponents know it in detail. (A former official at NSA's National Computer Security Center told me that the standard assumption there was that ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volapük
Volapük (; , 'Language of the World', or lit. 'World Speak') is a constructed language created in 1879 and 1880 by Johann Martin Schleyer, a Roman Catholic priest in Baden, Germany, who believed that God told him to create an international language. Notable as the first major constructed international auxiliary language, the grammar comes from European languages and the vocabulary mostly from English (with some German and French). However, the roots are often distorted beyond recognition. Volapük conventions took place in 1884 (Friedrichshafen), 1887 (Munich) and 1889 (Paris). The first two conventions used German, and the last conference used only Volapük. By 1889, there were an estimated 283 clubs, 25 periodicals in or about Volapük, and 316 textbooks in 25 languages;Handbook of Volapük , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Liège Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the Midd ...

People From Nuth
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

19th-century Cryptographers
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confirm cer ...

Scandinavia
Scandinavia is a subregion#Europe, subregion of northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. ''Scandinavia'' most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer to the Scandinavian Peninsula (which excludes Denmark but includes a part of northern Finland). In English usage, Scandinavia is sometimes used as a synonym for Nordic countries. Iceland and the Faroe Islands are sometimes included in Scandinavia for their Ethnolinguistics, ethnolinguistic relations with Sweden, Norway and Denmark. While Finland differs from other Nordic countries in this respect, some authors call it Scandinavian due to its economic and cultural similarities. The geography of the region is varied, from the Norwegian fjords in the west and Scandinavian mountains covering parts of Norway and Sweden, to the low and flat areas of Denmark in the south, as well as archipelagos and lakes in the east.

Key (cryptography)
A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key being maintained. A key's security strength is dependent on its algorithm, the size of the key, the generation of the key, and the process of key exchange. Scope The key is what is used to encrypt data from plaintext to ciphertext. There are different methods for utilizing keys and encryption. Symmetric cryptography Symmetric cryptography refers to the practice of the same key being used for both encryption and decryption. Asymmetric cryptography Asymmetric cryptography has separate keys for encrypting and decrypting. These keys are known as the public and private keys, respectively. Purpose Since the key ...

Constructed Language
A constructed language (shortened to conlang) is a language whose phonology, grammar, orthography, and vocabulary, instead of having developed natural language, naturally, are consciously devised for some purpose, which may include being devised for a fiction, work of fiction. A constructed language may also be referred to as an artificial, planned or invented language, or (in some cases) a fictional language. ''Planned languages'' (or engineered languages / engelangs) are languages that have been purposefully designed; they are the result of deliberate, controlling intervention and are thus of a form of ''language planning''. There are many possible reasons to create a constructed language, such as to ease human communication (see international auxiliary language and code); to give fiction or an associated constructed setting an added layer of realism; for experimentation in the fields of linguistics, cognitive science, and machine learning; for artistic language, artistic crea ...
