Vatsyayana Cipher
Mlecchita Vikalpa is one of the 64 arts listed in Vatsyayana's Kamasutra. The list appears in Chapter 3 of Part I of Kamasutra and Mlecchita Vikalpa appears as the 44th item in the list. The term Mlecchita Vikalapa has been translated into English as "the art of understanding writing in cypher, and the writing of words in a peculiar way". Introduction Mlecchita Vikalpa is the art of secret writing and secret communications. In ''The Codebreakers'', a 1967 book by David Kahn about the history of cryptography, the reference to Mlecchita Vikalpa in Kamasutra is cited as proof of the prevalence of cryptographic methods in ancient India. Though Kamasutra does not have details of the methods by which people of that time practiced this particular form of art, later commentators of Kamasutra have described several methods. For example, Yasodhara in his Jayamangala commentary on Kamasutra gives descriptions of methods known by the names ''Kautilya'' and ''Muladeviya''. The ciphers describ ...

Mulabhadra
Mūlabhadra (മൂലഭദ്ര) aka Mūlabhadri (:ml:മൂലഭദ്രി) was a secret method of communication employed by the royal spies of the erstwhile Travancore Kingdom during the medieval period. The scheme was also colloquially referred to as Mūlapatra. It was essentially a cryptographic scheme involving a partial transposition of the letters of the Malayalam alphabet. The scheme had been extensively used by Marthanda Varma, King Marthanda Varma (1706–1758) of Travancore Kingdom and his spies both for oral and written communication of messages. It was a fixed one-time unchangeable code in as much as it did not employ any key in its implementation in contrast to modern methods of substitution ciphers involving the utilisation of a key for generating a system of codes. ''Mūlabhadra'' is the only such scheme known to have been used in governance in this part of India during this period.The only known speaker of the language currently is K. N. Mohan, Ettumanoor, ...

Military Communications
Military communications or military signals involve all aspects of communications, or conveyance of information, by armed forces. Military communications span from pre-history to the present. The earliest military communications were delivered by runners. Later, communications progressed to visual and audible signals, and then advanced into the electronic age. Examples from '' Jane's Military Communications'' include text, audio, facsimile, tactical ground-based communications, naval signalling, terrestrial microwave, tropospheric scatter, satellite communications systems and equipment, surveillance and signal analysis, security, direction finding and jamming. IHS Jane'sMilitary Communications Retrieved 2012-01-23. History In past centuries communicating a message usually required someone to go to the destination, bringing the message. Thus, the term ''communication'' often implied the ability to transport people and supplies. A place under siege was one that lost ...

History Of Cryptography
Cryptography, the use of codes and ciphers to protect secrets, began thousands of years ago. Until recent decades, it has been the story of what might be called classical cryptography — that is, of methods of encryption that use pen and paper, or perhaps simple mechanical aids. In the early 20th century, the invention of complex mechanical and electromechanical machines, such as the Enigma rotor machine, provided more sophisticated and efficient means of encryption; and the subsequent introduction of electronics and computing has allowed elaborate schemes of still greater complexity, most of which are entirely unsuited to pen and paper. The development of cryptography has been paralleled by the development of cryptanalysis — the "breaking" of codes and ciphers. The discovery and application, early on, of frequency analysis to the reading of encrypted communications has, on occasion, altered the course of history. Thus the Zimmermann Telegram triggered the United States' ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pig Latin
Pig Latin is a language game or argot in which words in English are altered, usually by adding a fabricated suffix or by moving the onset or initial consonant or consonant cluster of a word to the end of the word and adding a vocalic syllable to create such a suffix. For example, Wikipedia would become Ikipediaway (taking the 'W' and 'ay' to create a suffix). The objective is to conceal the words from others not familiar with the rules. The reference to Latin is a deliberate misnomer; Pig Latin is simply a form of argot or jargon unrelated to Latin, and the name is used for its English connotations as a strange and foreign-sounding language. It is most often used by young children as a fun way to confuse people unfamiliar with Pig Latin. Origins and history Early mentions of pig Latin or hog Latin describe what we would today call dog Latin, a type of parody Latin. Examples of this predate even Shakespeare, whose 1598 play, ''Love's Labour's Lost'', includes a reference to d ...

Language Game
A language game (also called a cant, secret language, ludling, or argot) is a system of manipulating spoken words to render them incomprehensible to an untrained listener. Language games are used primarily by groups attempting to conceal their conversations from others. Some common examples are Pig Latin; the Gibberish family, prevalent in the United States and Sweden; and Verlan, spoken in France. A common difficulty with language games is that they are usually passed down orally; while written translations can be made, they are often imperfect, and thus spelling can vary widely. Some factions argue that words in these spoken tongues should simply be written the way they are pronounced, while others insist that the purity of language demands that the transformation remain visible when the words are imparted to paper. Use Some language games such as Pig Latin are so widely known that privacy is virtually impossible, as most people have a passable understanding of how it works a ...

Yudhishthira
''Yudhishthira'' (Sanskrit: युधिष्ठिर, IAST: ''Yudhiṣṭhira'') is the eldest among the five Pandava brothers. He is mentioned in the ancient epic Mahabharata. He was sired by King Pandu of the Kuru Dynasty and his first wife, Kunti. Yudhishthira is later crowned the king of Indraprastha with his capital at Hastinapura. From his childhood, Yudhishthira was greatly influenced by his uncle Vidura and his great uncle Bhishma, and believed in the virtues of '' dharma''. He was trained by two warrior-sages, Kripacharya and Dronacharya. Yudhisthira was appointed as the crown prince of Hastinapura, but was later replaced by Duryodhana. Because of Kunti's misunderstanding, Yudhishthira and his siblings had a polyamorous marriage with Draupadi, the princess of Panchala. Dhritarashtra, on Bhishma's request, divided his kingdom to end the succession dispute between Yudhishthira and Duryodhana. The eldest son of Pandu was given a barren land to rule, which ...

Vidura
Vidura (Sanskrit: विदुर, lit. ''skilled'', ''intelligent'' or ''wise''), also known as Kshatri, plays a key role in the Hindu epic ''Mahabharata''. He is described as the prime minister of the Kuru kingdom and is the paternal uncle of both the Pandavas and the Kauravas. Legend Mandavya's Curse The sage Mandavya cursed Yama that he would be born as a maid's son for getting him impaled without a valid reason. He was born in the mortal world as Vidura. Birth and early life Vidura was born through Niyoga between the sage Vyasa and Parishrami, a handmaiden to the queens Ambika and Ambalika. Ambika first mated with Vyasa but kept her eyes closed during their love making because his appearance and power frightened her. Because of this cowardice and disrespect she gave birth to the blind Dhritarashtra. Later her sister Ambalika mated with Vyasa, and knew to keep her eyes open. But she was pale with fear during the love making, and so gave birth to the albino Pandu. Fin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pandavas
The Pandavas (Sanskrit: पाण्डव, IAST: Pāṇḍava) refers to the five legendary brothers— Yudhishthira, Bhima, Arjuna, Nakula and Sahadeva—who are the central characters of the Hindu epic ''Mahabharata''. They are acknowledged as the sons of Pandu, the King of Kuru, but were fathered by different ''Devas'' (gods) due to Pandu's inability to naturally conceive children. In the epic, the Pandavas married Draupadi, the princess of Panchala, and founded the city of Indraprastha after the Kuru Kingdom was split to avoid succession disputes. After their paternal cousins the Kauravas—led by Duryodhana—tricked them into surrendering their kingdom and refused to return it, the Pandavas waged a civil war against their extended family, and this conflict was known as the Kurukshetra War. With the help of the god Krishna, the Pandavas eventually won the war with the death of the Kauravas, albeit at great cost. Etymology The word ''Pandava'' ( sa, पाण्ड ...

Duryodhana
Duryodhana ( sa, दुर्योधन, ) also known as Suyodhana, is the primary antagonist in the Hindu epic ''Mahabharata.'' He was the eldest of the Kauravas, the hundred sons of the blind king Dhritarashtra and his queen Gandhari. Being the first-born son of the blind king, he was the crown prince of the Kuru Kingdom and its capital of Hastinapura, often forced into ceding the title to his cousin Yudhishthira, who was older than him. Karna was the prince's closest friend. Notably, Duryodhana, with significant assistance from Karna, performs the Vaishnava Yagna when the Pandavas are in exile. Duryodhana used his greater skill in wielding the mace to defeat his opponents. He was also an extremely courageous warrior and was said to be a good ruler. Duryodhana's greed and arrogance were the two qualities said to have led to his downfall in the Mahabharata. Etymology The Sanskrit word, ''Duryodhana'' means "invincible" in battle.

Mahabharata
The ''Mahābhārata'' ( ; sa, महाभारतम्, ', ) is one of the two major Sanskrit literature, Sanskrit Indian epic poetry, epics of ancient India in Hinduism, the other being the ''Ramayana, Rāmāyaṇa''. It narrates the struggle between two groups of cousins in the Kurukshetra War and the fates of the Kaurava and the Pandava, Pāṇḍava princes and their successors. It also contains Hindu philosophy, philosophical and devotional material, such as a discussion of the four "goals of life" or ''purusharthas, puruṣārtha'' (12.161). Among the principal works and stories in the ''Mahābhārata'' are the ''Bhagavad Gita'', the story of Damayanti, the story of Shakuntala, the story of Pururava and Urvashi, the story of Savitri and Satyavan, the story of Kacha (sage), Kacha and Devayani, the story of Rishyasringa and an abbreviated version of the ''Ramayana, Rāmāyaṇa'', often considered as works in their own right.
