Communication through Photon UsingQuantum Cryptography: A Survey

Leenata B. Isal, Chetan Jagannath Shelke

Quantum cryptography is an approach toward secure communication by applying the phenomena of quantum physics. As compared to the classical cryptography, quantum cryptography provides more secure communication whose security depends only on the validity of quantum theory. It is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. Quantum cryptography is one of the few commercial applications of quantum physics at the quantum level. The quantum relies on two important elements of quantum mechanics- the Heisenberg uncertainty principle and principle of photon polarization.

Quantum Cryptography: Advancements and Applications in Securing Networking Systems

Mohan Garg, Kambam Vedantan, I. Rexiline Sheeba +3 more

Quantum cryptography is an advanced technology that applies the principles of quantum mechanics to provide secure communication networks. Quantum crypto differs from other forms of cryptographic security that rely on mathematical theory because this allows quantum mechanics, the uncertainty principle and entanglement to enhance secure communication. Quantum cryptography has made significant progress recently and can effectively be used for networking system protection. Such advancement is the quantum key distribution protocol, where two parties generate the secret key to secure communication completely unshakable by any third party. One more advancement is the use of quantum teleportation, which allows transferring information between distant quantum systems without physically moving there. These developments have provided abundant opportunities for applications of quantum cryptography to secure networking systems. It helps maintain the secure transmission of sensitive information online or protects financial transactions and government and military communications. Quantum cryptography can also be used for secure authentication and access control, useful in cross-industry applications. Quantum cryptography is the best technology for implementing secure networking systems; thanks to its crypt-like harmony, it can be integrated into the most insecure networks with very rare error rates.

QUANTUM CRYPTOGRAPHY: PRINCIPLES, PROBLEMS, AND PROSPECTS

Ілля Геннадійович Калюжний

Quantum cryptography is a relatively new but promising method for secure data transmission. Today it is believed that it can ensure the absolute secrecy of data, resulting from the principles of quantum physics, on which it is based, namely the uncertainty principle of quantum Heisenberg. According to this principle cannot measure any aspect of photons without distorting thus irrevocably different option. That is the recipient of a message knows when attempting invasion in this necessarily knows.To create a quantum communication channel often use fiber optic lines or open space in which carriers serve single photons or pairs of entangled photons are often used.Three tasks facing cryptography are:1. Ensuring the confidentiality of messages sent via open communication channels.2. Authentication messages that confirm the validity of the information received and sent.3. Installing intrusion in fact, if it took place.Given the importance of information security, quantum cryptography technology will soon be available not only banks or large corporations but also individuals. Leading IT companies are in search of optimum circuit solutions that would produce industrial equipment for the transmission of confidential information available for mass use. The main obstacles for implementation of quantum cryptography methods are short distances, which can transmit information with modern facilities, high cost and cumbersome equipment. To solve these problems prompted the idea of creating a hybrid air-fiber system using satellite communications is proposed. The use of artificial satellites for the transmission of photons through the air opens the possibility of secret key clients in any part of the Earth and even beyond.It is also appropriate to review the possibility of using existing telecommunication and electrical networks for the transmission of quantum keys.

A Survey on Various Aspects of Quantum Cryptography

Rajesh Kumar Pateriya, Dr.J.L. Rana, Anupriya Gupta

In the era of information technology the need for secure communication has become increasingly important. Cryptography is a technology for creating the core of information security we use cryptography for making data secure which is the science of information protection from unauthorized interception and tempering. Most modern cryptographic studies design cryptosystems and algorithms using mathematical concepts which are based either on factorization or on discrete logarithm problem. In recent years quantum information research has lead to the discovery of a number of remarkable new paradigms for information processing and communication. These developments include quantum cryptography schemes that offer unconditionally secure information transport guaranteed by quantum-mechanical laws, which provide protection of system security, and optimization of system efficiency and detects intrusion and wiretap. Today quantum cryptography is used in various application for transferring secure data without the fear of keys being compromised. This paper reviews the various areas where quantum  cryptography is successfully implemented, its advantages disadvantages & technical issues.
