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 a ...

Kerckhoffs's Principle
Kerckhoffs's principle (also called Kerckhoffs's desideratum, assumption, axiom, doctrine or law) of cryptography was stated by Dutch-born 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 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] |
Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volapük
Volapük (; , "Language of the World", or lit. "World Speak") is a constructed language created between 1879 and 1880 by Johann Martin Schleyer, a Catholic priest in Baden, Germany, who believed that God had told him in a dream 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;/ref> Schleyer's 1880 Volapük as well as Modern Volapük has minimal pair, minimal ''l–r'' pairs such as ''rel'' "religion" versus ''lel'' "iron".

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 pro ...

Lycée Arago (Paris)
The lycée Arago is a Parisian secondary school and sixth-form located on place de la Nation. It teaches both general and technical education. It celebrated its centenary in 1980. History Built in 1880, the lycée Arago started as a higher primary school (EPS). Schools of this type were created by François Guizot under the law of 1833 to widen secondary education to those children from poorer families. The EPS in Paris particularly were real colleges. All the disciplines usually associated with the royal colleges were offered, apart from Greek and Latin, which were replaced by foreign languages. Students at the école Arago even received calligraphy classes. The Parisian EPS were a great success. They prepared students for schools such as the École de physique et chimie de Paris, the École nationale des Arts et Métiers, and the École normale d'instituteurs. The estimated cost for the école Arago was gold francs (1877) just for construction. This cost did not inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rule Of Thumb
In English, the phrase ''rule of thumb'' refers to an approximate method for doing something, based on practical experience rather than theory. This usage of the phrase can be traced back to the 17th century and has been associated with various trades where quantities were measured by comparison to the width or length of a thumb. A modern folk etymology holds that the phrase is derived from the maximum width of a stick allowed for wife-beating under English common law, but no such law ever existed. This belief may have originated in a rumored statement by 18th-century judge Sir Francis Buller that a man may beat his wife with a stick no wider than his thumb. The rumor produced numerous jokes and satirical cartoons at Buller's expense, but there is no record that he made such a statement. English jurist Sir William Blackstone wrote in his ''Commentaries on the Laws of England'' of an "old law" that once allowed "moderate" beatings by husbands, but he did not mention thumbs or any ...

Constructed Language
A constructed language (sometimes called a conlang) is a language whose phonology, grammar, and vocabulary, instead of having developed naturally, are consciously devised for some purpose, which may include being devised for a 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 creation; and for language games.
