Abstract

Quantum cryptography, a field of science that had not been known before, developed rapidly in the late 20th century. It originated from a combination of quantum mechanics and information technology. The present paper presents the possibilities of using quantum mechanics in cryptography and considers whether there are any practical solutions to the important class of problems regarding the security of transmitted information.

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.

Quantum cryptography: Approaching communication security from a quantum perspective

A. Porzio

Quantum cryptography aims at solving the everlasting problem of unconditional security in private communication. Every time we send personal information over a telecom channel a sophisticate algorithm protect our privacy making our data unintelligible to unauthorized receivers. These protocols resulted from the long history of cryptography. The security of modern cryptographic systems is guaranteed by complexity: the computational power that would be needed for gaining info on the code key largely exceed available one. Security of actual crypto systems is not “by principle” but “practical”. On the contrary, quantum technology promises to make possible to realize provably secure protocols. Quantum cryptology exploits paradigmatic aspects of quantum mechanics, like superposition principle and uncertainty relations. In this contribution, after a brief historical introduction, we aim at giving a survey on the physical principles underlying the quantum approach to cryptography. Then, we analyze a possible continuous variable protocol.

A study on the development of quantum cryptography and some challenging issues

Malinka Ivanova, Emanuil Ilchov

Quantum cryptography is a revolutionary field that applies the principles of quantum mechanics to provide secure communication channels. One of the most popular techniques in quantum cryptography is Quantum Key Distribution, which uses quantum states to deliver secure keys. The main advantage of quantum cryptography is that it offers protection against eavesdropping and tampering, which is not possible with classical encryption methods. This is because copying data in a quantum state is virtually impossible, and any attempt to intercept or manipulate the data will result in its complete alteration. As a result, any third-party interference can be detected quickly. Traditional cryptographic algorithms used in modern cryptography are vulnerable to attacks due to the evolution of quantum computers and mathematical advances in the decomposition of large integers. Therefore, the solution to address this vulnerability is to apply the principles of quantum physics to cryptography. The aim of the paper is to survey the current scientific achievements in the field of quantum cryptography and to present some challenging issues.
