Abstract

There are multiple encryption techniques at present time but they cannot provide sufficient security. Thus security is still a challenging issue of communications. By the Since now –a-days security is the primary concern for any organization. This paper suggest a new approach of quantum computation. In this approach fingerprint and quantum mechanical affect creates new and highly secure network.

A Secure Method of Communication in Conventional Cryptography using Quantum Key Distribution

Chunduru Anilkumar, Bhavani Gorle, Kinthali Sowmya

Security knowledge is one of the foremost challenges in the present day. When the topic is about Information security, the concept of cryptography comes into the picture. Every day, people and organizations use cryptography to maintain the confidentiality of their communications and data as well as to preserve their privacy. Today, one of the most successful methods used by businesses to protect their storage systems, whether at rest or in transit, is cryptography. Yet, cryptography is an effective technique to secure the data, the modern technology can break the cryptographic techniques. But some data encryption algorithms are several times stronger than today's conventional cryptography and can be constructed using quantum computing. They are "Quantum Cryptographic Algorithms ". Quantum cryptography uses the rules of quantum physics instead of classical encryption, which is based on mathematics, to protect and transmit data in a way that cannot be intercepted. Quantum key distribution is the greatest illustration of quantum cryptography and offers a safe solution to the key exchange issue. The proposed work deals with quantum cryptography and mainly focuses on how the quantum cryptographic algorithm is more secure than traditional cryptography.

Cryptography is an art and science of secure communication. Here the sender and receiver are guaranteed the security through encryption of their data, with the help of a common key. Both the parties should agree on this key prior to communication. The cryptographic systems which perform these tasks are designed to keep the key secret while assuming that the algorithm used for encryption and decryption is public. Thus key exchange is a very sensitive issue. In modern cryptographic algorithms this security is based on the mathematical complexity of the algorithm. But quantum computation is expected to revolutionize computing paradigm in near future. This presents a challenge amongst the researchers to develop new cryptographic techniques that can survive the quantum computing era. This paper reviews the radical use of quantum mechanics for cryptography.

The emergence of quantum computing poses significant risks to conventional network security, prompting researchers to focus on developments in quantum cryptography, particularly Quantum Key Distribution (QKD).According to research, it has been found that traditional security methods, like RSA encryption, could potentially be at risk from quantum algorithms.On the other hand, quantum cryptography is a field of study that leverages the principles of quantum mechanics to improve the security of communication.One of the techniques used in quantum cryptography is Quantum Key Distribution (QKD), which makes use of the unique properties of quantum particles such as photons to securely distribute encryption keys and detect any potential eavesdropping attempts, thanks to the uncertainty principle.Nevertheless, the integration of QKD into current network infrastructures poses significant challenges due to the required technological advancements.This study offers a comprehensive analysis of the fundamental principles underlying quantum cryptography, the obstacles that arise during its implementation, and its potential prospects for protecting against the risks posed by advancements in quantum computing.Furthermore, this study delves into the potential consequences of these technological advancements across different industries and emphasizes the need to create algorithms that can withstand quantum attacks to guarantee strong data security in the age of digitalization.

Quantum cryptography: An emerging technology in network security

Mehrdad S. Sharbaf

The uses of computer communications networks technologies have increased the incidents of computer abuse. Because of these incidents, most organizations facing pressure to protect their assets. Most digital networks generally rely on modern cryptosystems to secure the confidentiality and integrity of traffic carried across the network. The current modern cryptosystems based on mathematical model introduce potential security holes related to technological progress of computing power, the key refresh rate and key expansion ratio, the most crucial parameters in the security of any cryptographic techniques. For that reason efforts have been made to establish new foundation for cryptography science in the computer communications networks. One of these efforts has led to the development of quantum cryptography technology, whose security relies on the laws of quantum mechanics [1,2,3,20, 24]. This research paper concentrates on quantum cryptography, and how this technology contributes to the network security. The scope of this research paper is to cover the weaknesses, and the security pitfalls in modern cryptography, fundamental concepts of quantum cryptography, the real - world application implementation of this technology, finally the future direction in which the quantum cryptography is headed forwards.
