Abstract

Cryptography is used for the secure communication in which two parties are involved. The most popular cryptographic issue is the transmission of confidential messages. The privacy is maintained using the cryptographic protocol. The security of quantum cryptography relies more on physics including quantum mechanics and statistics rather than on solving mathematical problems. A well-known application of quantum cryptography is quantum key distribution (QKD) that is used to establish communication by generating cryptographic keys. Moreover, it is based on the Heisenberg uncertainty principle that ensures the security and prevents from eavesdropping. Basically, quantum cryptography with faint laser pulses, polarization coding, phase coding, and frequency coding have been discussed.

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. This paper focuses on the principle of quantum cryptography and how this technology contributes in security of network.

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: Secure Communication Beyond Classical Limits

Rohit Goyal

Quantum cryptography promises secure communication protocols that surpass the limitations of classical cryptography. By leveraging the principles of quantum mechanics, particularly the phenomenon of quantum entanglement and the uncertainty principle, quantum cryptography protocols offer provable security guarantees against eavesdropping attacks. In this paper, we provide an overview of quantum cryptography, discussing its theoretical foundations, key protocols such as quantum key distribution (QKD), and experimental implementations. We highlight the advantages of quantum cryptography over classical cryptographic techniques and explore its potential applications in secure communication networks, financial transactions, and data privacy. Furthermore, we discuss ongoing research efforts and challenges in the practical deployment of quantum cryptography systems, including the development of robust quantum hardware and the integration of quantum cryptographic protocols into existing communication infrastructures. Overall, quantum cryptography holds great promise for enabling secure communication channels that are resilient to quantum attacks, paving the way for a new era of ultra-secure information exchange.
