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 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.

Mlecchita Vikalpa
Mlecchita Vikalpa is one of the 64 arts listed in Vatsyayana's Kamasutra, translated into English as "the art of understanding writing in cypher, and the writing of words in a peculiar way". The list appears in Chapter 3 of Part I of Kamasutra and Mlecchita Vikalpa appears as the 44th item in the list. 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 described in the Jayamangala commentary are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malayalam Script
Malayalam script (; / ) is a Brahmic scripts, Brahmic script used to write Malayalam, the principal language of Kerala, India, spoken by 45 million people. It is a Dravidian language spoken in the Indian state of Kerala and the union territories of Lakshadweep and Puducherry (Mahé district) by the Malayali people. It is one of the official scripts of the Indian Republic. The Malayalam script resembles Tulu script and Tigalari script, used to write the Tulu language, spoken in Tulu Nadu, coastal Karnataka (Dakshina Kannada and Udupi district, Udupi districts) and the northernmost Kasargod district of Kerala. Like many Indic scripts, it is an alphasyllabary (abugida), a writing system that is partially "alphabetic" and partially syllable-based. The modern Malayalam alphabet has 15 vowel letters, 42 consonant letters, and a few other symbols. The Malayalam script is a Vatteluttu alphabet extended with symbols from the Grantha alphabet to represent Indo-Aryan languages, Ind ...

Cipher Text
In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it. This process prevents the loss of sensitive information via hacking. Decryption, the inverse of encryption, is the process of turning ciphertext into readable plaintext. Ciphertext is not to be confused with codetext because the latter is a result of a code, not a cipher. Conceptual underpinnings Let m\! be the plaintext message that Alice wants to secretly transmit to Bob and let E_k\! be the encryption cipher, where _k\! is a cryptographic key. Alice must first transform the plaintext into ciphertext, c\!, in order to securely send the message to Bob, as follows: : c = E_k(m). \! In a symmetric-key system, Bob knows Alice's encryption key.

History Of Cryptography
Cryptography, the use of codes and ciphers, 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' entry into World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shloka
Shloka or śloka ( , from the root , Macdonell, Arthur A., ''A Sanskrit Grammar for Students'', Appendix II, p. 232 (Oxford University Press, 3rd edition, 1927).) in a broader sense, according to Monier-Williams's dictionary, is "any verse or stanza; a proverb, saying"; but in particular it refers to the 32- syllable verse, derived from the Vedic '' anuṣṭubh'' metre, used in the '' Bhagavad Gita'' and many other works of classical Sanskrit literature. In its usual form it consists of four '' pādas'' or quarter-verses, of eight syllables each, or (according to an alternative analysis) of two half-verses of 16 syllables each. The metre is similar to the Vedic '' anuṣṭubh'' metre, but with stricter rules. The ''śloka'' is the basis for Indian epic poetry, and may be considered the Indian verse form ''par excellence'', occurring as it does far more frequently than any other metre in classical Sanskrit poetry. The ''śloka'' is the verse-form generally used in the '' Maha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanskrit
Sanskrit (; stem form ; nominal singular , ,) is a classical language belonging to the Indo-Aryan languages, Indo-Aryan branch of the Indo-European languages. It arose in northwest South Asia after its predecessor languages had Trans-cultural diffusion, diffused there from the northwest in the late Bronze Age#South Asia, Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a lingua franca, link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting effect on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Indo-Aryan languages# ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mnemonic
A mnemonic device ( ), memory trick or memory device is any learning technique that aids information retention or retrieval in the human memory, often by associating the information with something that is easier to remember. It makes use of elaborative encoding, retrieval cues and imagery as specific tools to encode information in a way that allows for efficient storage and retrieval. It aids original information in becoming associated with something more accessible or meaningful—which in turn provides better retention of the information. Commonly encountered mnemonics are often used for lists and in auditory system, auditory form such as Acrostic, short poems, acronyms, initialisms or memorable phrases. They can also be used for other types of information and in visual or kinesthetic forms. Their use is based on the observation that the human mind more easily remembers spatial, personal, surprising, physical, sexual, humorous and otherwise "relatable" information rather tha ...

Clear Text
In cryptography, plaintext usually means unencrypted information pending input into cryptographic algorithms, usually encryption algorithms. This usually refers to data that is transmitted or stored unencrypted. Overview With the advent of computing, the term ''plaintext'' expanded beyond human-readable documents to mean any data, including binary files, in a form that can be viewed or used without requiring a key or other decryption device. Information—a message, document, file, etc.—if to be communicated or stored in an unencrypted form is referred to as plaintext. Plaintext is used as input to an encryption algorithm; the output is usually termed ciphertext, particularly when the algorithm is a cipher. Codetext is less often used, and almost always only when the algorithm involved is actually a code. Some systems use multiple layers of encryption, with the output of one encryption algorithm becoming "plaintext" input for the next. Secure handling Insecure handling of ...

Travancore Kingdom
The kingdom of Travancore (), also known as the kingdom of Thiruvithamkoor () or later as Travancore State, was a kingdom that lasted from until 1949. It was ruled by the Travancore Royal Family from Padmanabhapuram, and later Thiruvananthapuram. At its zenith, the kingdom covered most of the south of modern-day Kerala (Idukki, Kottayam, Alappuzha, Pathanamthitta, Kollam, and Thiruvananthapuram districts, major portions of Ernakulam district, Puthenchira village of Thrissur district) and the southernmost part of modern-day Tamil Nadu ( Kanyakumari district and some parts of Tenkasi district) with the Thachudaya Kaimal's enclave of Irinjalakuda Koodalmanikyam temple in the neighbouring kingdom of Cochin. However Tangasseri area of Kollam city and Anchuthengu near Attingal in Thiruvananthapuram were parts of British India.

Marthanda Varma
Anizham Thirunal Marthanda Varma (Malayalam: ; 1706 – 7 July 1758) was the founding monarch of the southern Indian Kingdom of Travancore (previously Venadu) from 1729 until his death in 1758. He was succeeded by Rama Varma ("Dharma Raja") (1758–98).Subrahmanyam, Sanjay''The south: Travancore and Mysore''"India". Encyclopædia Britannica. Marthanda Varma defeated the Dutch East India Company forces at the Battle of Colachel in 1741. He also put an end to the ettuveetil pillamars and the ettara yogam council and took the full power as a king. The Yogakars and Pillamars were always against the Royal Family of Venad (Padmabhaswamy Temple Judgement page :16) He then adopted a European mode of discipline for his army and expanded his kingdom northward (to what became the modern state of Travancore). He built a sizeable standing army of about 50,000 nair men, as part of designing an "elaborate and well-organised" war machine, with the role of the travancore army and fortified ...
