Cryptographic protection of information using quantum cryptography

Abstract

In the modern world, one of the most reliable ways to keep all types of communications or information transmitted over computer networks secret is the use of quantum cryptography. The idea of ​​using quantum cryptography to protect information by exploiting the nature of microscopic objects—quantum light (photons), whose behavior is subject only to the laws of physics—has become the most relevant and reliable application. Despite the fact that commercially available quantum cryptography devices are already available, scientific advances in this field are still underway.

Quantum Cryptography: A Brief Review of the Recent Developments and Future Perspectives

Azeem Iqbal, Muhammad Junaid Aslam, Sahar Hafiza Nayab

Quantum Cryptography is a novel approach to make the information and network world more secure. Unlike classical cryptography, quantum cryptography ensures the security of communication because it is based on the laws of Quantum Mechanics; a branch of physics that deals with the fundamental behavior of matter and their energies to the levels of subatomic particles. These particles and their intrinsic properties such as photon polarization and entanglement allow us to develop an unbreakable system of cryptographic information. Conventionally, the security has been primarily concerned with the secured distribution of secret key carried over an insecure channel. However, in Quantum Cryptographic systems the transmission of secret key is done using aforementioned laws of nature through a secured quantum channel highly susceptible to intrusion detection. Consequently, the Quantum Key Distribution (QKD), in conjunction with protocols such as BB84 protocol has emerged as an ultimate modern secured communication system. This article concentrates on briefly reviewing quantum cryptography, some recent developments and reports of its vulnerabilities.

Quantum Cryptography: Realizing next generation information security

Payal P. Kilor

Quantum cryptography is a technology that ensures ultimate security. Compared to current cryptography that could be defeated by by the development of an ultra high-speed computer, quantum cryptography ensures secure communication because it is based on the fundamental physical laws. 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 a new method for secret communications offering the ultimate security assurance of the inviolability of a Law of Nature. The quantum cryptography relies relies on two important elements of quantum mechanics-the Heisenberg Uncertainty principle and the principle of photon polarization. This research paper concentrates on the principle of quantum cryptography, and how this technology contributes to the network security. This paper outlines the real world application implementation of this technology and the future direction in which quantum cryptography accelerates.

The security of quantum cryptography

Justin C. Miller

A common desire in today's world is that of security. Whether it is keeping your e-mail private or stopping the government from hacking into your computer, the idea behind cryptography is to communicate between two parties in different locations, and to secure this information from outsiders. During the last half century there have been numerous advances in encryption schemes and also in the machines that process such information. Modern encryption algorithms have become increasingly more complex with advances in computers and technology, and encryption algorithms such as RSA and DES have been presented as algorithms that have remained secure for decades. These recent advances in encryption schemes will be examined in the first part of this paper. On the other hand, because the security of classical ciphers relies on the secrecy of a key, advances in research and computing may begin to compromise the security of these cryptosystems, as quantum computers would be capable of mathematical calculations that could break many modern encryption algorithms. Unlike classical cryptosystems, quantum cryptography obeys the laws of quantum physics, resulting in a much stronger, provable security. Many great advances have come in recent decades, and the latter part of this paper deals with these advances as well as the phenomena of quantum physics, the evolution of quantum computing, and the study of quantum cryptography.

Quantum Cryptography: Mathematical Foundations and Practical Applications for Secure Communication Protocols

Shilpa Vikas Shinde

Quantum cryptography is a new and exciting area that uses quantum physics to protect communication lines from being spied on or intercepted. Fundamental ideas in this field, like the uncertainty principle and the fact of quantum entanglement, are used to achieve levels of security that have never been seen before. Our in-depth study, "Quantum Cryptography: Mathematical Foundations and Practical Applications for Secure Communication Protocols," looks at both the math behind quantum cryptographic protocols and how they are used in the real world. Our study goes into great detail about the theories behind quantum cryptography. It explains ideas like quantum key distribution (QKD), quantum teleportation, and quantum secure direct communication (QSDC). One of the main ideas behind quantum cryptography is the idea of qubits, which are like regular bits but in quantum mechanics. They can be in more than one state at the same time because of superposition. Quantum cryptographic methods use this property to make sure communication is safe by putting data in quantum states and taking advantage of the fact that quantum measures are inherently unpredictable. The study we're doing looks at how to use quantum cryptography in typical everyday situations. We look at the problems that come up when you try to build infrastructure for quantum transmission, such as noise, decoherence, and scale. We make a plan for making strong and trustworthy quantum cryptographic systems by giving details about how experiments are set up and how technology is improving. Our study looks into how quantum cryptography could be used for things other than just keeping communications safe. We look into what it means for new technologies like quantum networks, quantum computing, and safe multi-party processing. We hope that by explaining the bigger effects of quantum cryptography, we can encourage more study and new ideas in this ground-breaking area.

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.
