Promise From the Future — Quantum Cryptography

S. Rajendirakumar

Cryptography is the science of securing information by transforming it into a form that cannot be easily understood by unauthorized individuals. Traditional cryptography is based on mathematical problems that are difficult to solve, but as quantum computers become more powerful, these problems will become easier to solve. Quantum cryptography is a promising approach to data security that is immune to attack by quantum computers. It uses the principles of quantum mechanics to create secure communication channels. This article provides an overview of quantum cryptography, including the basic principles, different types of quantum cryptographic protocols, and some of the challenges that are still being addressed. The article also discusses the potential of quantum cryptography to revolutionize data security in the future.

In recent years Quantum Cryptography gets more attention as well as becomes most promising cryptographic field for faster, effective and more secure communications. Quantum Cryptography is an art of science which overlap quantum properties of light under quantum mechanics on cryptographic task instead of current state of algorithms based on mathematical computing technology. Major algorithms for public key encryption and some digital signature scheme such as RSA, El Gamal cryptosystem, hash function are vulnerable at quantum adversaries. Most of the factoring problem can be broken by Shore's algorithm and quantum computer threatens other hand discrete logarithm problem. Our paper describes why modern cryptography contributes quantum cryptography, security issues and future goals of modern cryptography.

This article explores the rise of quantum cryptography as a groundbreaking approach to securing data beyond classical means.By harnessing the principles of quantum mechanics, quantum cryptography promises unparalleled levels of security, making it virtually impossible for adversaries to intercept or manipulate data without detection.The article delves into the fundamentals of quantum cryptography, its applications, challenges, and future prospects.
