Cryptography, Secrecy, confidences and security - Ancient practices and state-of-art techniques.

 

       

There will be between 20.4 billion and 31 billion IoT devices online by 2020.

Sage Report - Globally, 48% of small and mid-size businesses have experienced a cyber security incident in the past year.

 

What is Cryptography?

•        Cryptography, or cryptology - kryptos - Meaning - hidden, secret"; It is a technique for secure communication.

•        This is synonymous with “encryption”, which is basically concealing information. This is usually an Encryption is a mathematical process that encodes and modifies the data using an encryption algorithm and an allied key. 

•        Cryptography is the first-line shield and an ammunition for data protection.

The World History

The first recorded use of cryptography in the world history was by the Spartans in 400 BC. They had a cipher device called the scytale for secret communication. (https://www.britannica.com/topic/cryptology/History-of-cryptology)

How old in Cryptography in Bharath?

•        Ciphers, Enigmas and enciphering techniques and practices had been prevalent throughout history in every civilization in some form.

•        In Mahabharata, there is a reference that Vidhuran and King Yudishtra used a cyphered language to converse so as To prevent non-authorized people from understanding messages using the jargon of the Mlechchaas – This is the chapter Adi Parva

•        “Mlecchita Vikalpa” (म्लेच्छिता विकास) is one of the 64 arts described in Vatsyayana's Kamasutra (Chapter.3). Which Is a study of pictographic writing. There are also references to other methods for secret communications like Gudhayojya, Gudhapada and Gudhavarna (Mleccha in Sanskrit refers to 'copper – copper age.)

•        In the south, during the medieval period , Moolabhadri – was employed by the spies of the erstwhile of the Travancore samasthaanam( Kingdom) - (Raja Marthanda varma-1706–1758) - The mnemonic was very similar to Sanskrit slokams and these were one time usable codes.

•        The rest of the world do have evidences of Cryptographic writings starting for the Pyramid tops in Egypt, The cuneiform writing in Sumerian civilization, The Spartan crypto graphic messages- simple scytale messages, the Steganographic messages of the Greek, to Name a few.

•        Some of the German Machines in the world war time, had elaborative encoding, communication, storage and retrieval options.

•        1970's, IBM formed a "crypto group" headed by a a German-American, Horst-Feistel designed a cipher called Lucifer.

•        Cryptanalysis – A method to break cryptographic security systems and read the encrypted messages

Quantum Mechanics and Encryption.

Quantum Cryptography – Most sought-after technique nowadays is an encryption method that uses the inherent properties of quantum mechanics to transmit data.

The quantum key distribution (QKD) uses a series of photons which have uncertain states, multiple forms and exist everywhere. These key when disturbed alerts immediately.

 

Here are some points noted as potential synergy between Vedic Mathematics and quantum cryptography.

 

1. Responsive and Fast Arithmetic Calculations: Vedic Mathematics entails techniques for speed arithmetic calculations, which helps in optimizing the mathematical operations required for quantum cryptography algorithms. The mathematical bureaus and principles such as Number Theory, linear algebra, probability theory is well defined in Vedic Mathematics.
2. Algorithm Simplification: The problem-solving methods in Vedic Maths are simple and fast. Drawing upon these principles, implementing in quantum cryptography algorithms will route to potent, more precise and efficacious, streamlined processes.
3. Parallel Computation: Vedic Mathematics provides a unique and a atypical technique of solving algebraic and linear Equations on parallel platforms. This will be a pragmatic scheme in the development of more secure encryption algorithms which will be hostile and resistant to cyber-attacks.
4. Error Detection and Emendation: Quantum cryptography heavily relies on error detection and correction techniques. Vedic Mathematics can offer insights into efficient error correction methods that can further enhance the reliability of quantum communication.
5. Build Explainable Models:  Construct processes, workflows and methods which introduces human comprehension and thereby trust on results and output gotten from Intelligent systems and software

Thirukkural a classic Tamil literary treatise on day-to-day existence of common man, statecraft, politics, kingship, economics and military strategy.

The Epigram, Kural 590 is referred here to exhibit the law for a high hold of secrecy to be preserved and maintained by a ruler

சிறப்பறிய ஒற்றின்கண் செய்யற்க செய்யின்

புறப்படுத்தான் ஆகும் மறை.

sirappariya otrrinkan seiyatrka seiyin
purappaduththaan aakum marai

Meaning-Reward not trusty spy in others' sight,
Or all the mystery will come to light.
