Key distribution in PKC through Quantas

Cryptography literally means "The art & science of secret writing & sending a message between two parties in such a way that its contents cannot be understood by someone other than the intended recipient". and Quantum word is related with "Light". Thus, Quantum Cryptography is a way of descripting any information in the form of quantum particles. There are no classical cryptographic systems which are perfectly secure. In contrast to Classical cryptography which depends upon Mathematics, Quantum Cryptography utilizes the concepts of Quantum Physics which provides us the security against the cleverest marauders of the present age. In the view of increasing need of Network and Information Security, we do require methods to overcome the Molecular Computing technologies (A future technology) and other techniques of the various codebrakers. Both the parts i.e. Quantum Key distribution and Information transference from Sender to Receiver are much efficient and secure. It is based upon BB84 protocol. It can be of great use for Govt. agencies such as Banks, Insurance, Brokerages firms, financial institutions, e-commerce and most important is the Defense & security of any country. It is a Cryptographic communication system in which the original users can detect unauthorized eavesdropper and in addition it gives a guarantee of no eavesdropping. It proves to be the ultra secure mode of communication b/w two intended parties.Comment: 11 Pages, JGraph-Hoc Journal 201

A Talk on Quantum Cryptography, or How Alice Outwits Eve

Alice and Bob wish to communicate without the archvillainess Eve eavesdropping on their conversation. Alice, decides to take two college courses, one in cryptography, the other in quantum mechanics. During the courses, she discovers she can use what she has just learned to devise a cryptographic communication system that automatically detects whether or not Eve is up to her villainous eavesdropping. Some of the topics discussed are Heisenberg's Uncertainty Principle, the Vernam cipher, the BB84 and B92 cryptographic protocols. The talk ends with a discussion of some of Eve's possible eavesdropping strategies, opaque eavesdropping, translucent eavesdropping, and translucent eavesdropping with entanglement.Comment: 31 pages, 8 figures.

Human and Technical Factors in the Adoption of Quantum Cryptographic Algorithms

The purpose of this research is to understand what factors would cause users to choose quantum key distribution (QKD) over other methods of cryptography. An Advanced Encryption Standard (AES) key can be exchanged through communication using the Rivest, Shamir, Adleman (RSA) cryptographic algorithm, QKD, or post-quantum cryptography (PQC). QKD relies on quantum physics where RSA and PQC use complex mathematics to encrypt data. The BB84 quantum cryptographic protocol involves communication over a quantum channel and a public channel. The quantum channel can be technically attacked by beamsplitting or intercept/resend. QKD, like other forms of cryptography, is vulnerable to social attacks such as industrial espionage. QKD products can transmit over maximum distances ranging from 40 km up to 150 km with key rates as low as 1.4 kb/s up to at least 300 kb/s. A survey and focus group discussion with a defense contracting company revealed that while nobody fully trusts current security systems, they are more concerned about social engineering attacks before attacks on cryptography. The company is not interested in implementing QKD unless the range capabilities are improved or there is regulation requiring them to use it

Sistema de distribución de claves mediante criptografía cuántica para evadir ataques del tipo “Man in the middle”

Nowadays, it is possible to design very secure systems for key distribution. According to quantum cryptography, which is based on the properties of quantum mechanics, quantum key distribution systems are the most secure way to exchange private keys. This document leads you towards the understanding of these systems.Las nuevas técnicas criptográficas, como la criptografía cuántica, permiten diseñar sistemas de distribución cuánticos de claves con niveles de seguridad bastante altos. A lo largo de este documento se describirá como se comportan estos sistemas frente a ataques del tipo “Man in the middle” y que debilidades pueden llegar a presentar
