Abstract

Quantum communication offers unique features that have no classical analog, in particular, it enables provably secure quantum key distribution (QKD). Despite the benefits of quantum communication are well understood within the scientific community, the practical implementations sometimes meet with scepticism or even resistance. In a recent publication [1], NSA claims that QKD is inferior to "quantum-resistant" cryptography and does not recommend it for use. Here we show that such a sceptical approach to evaluation of quantum security is not well justified. We hope that our arguments will be helpful to clarify the issue.

A correct security evaluation of quantum key distribution

Osamu Hirota

There is no doubt that quantum key distribution is an excellent result as a science. However, this paper presents a view on quantum key distribution (QKD) wherein QKD may have a difficulty to provide a sufficient security and good communication performance in real world networks. In fact, a one-time pad forwarded by QKD model with $\barε=10^{-6}$ may be easily decrypted by key estimation. Despite that researchers know several criticisms on the theoretical incompleteness on the security evaluation, Portmann and Rennner, and others still avert from the discussion on criticism, and experimental groups tend to make exaggerated claims about their own work by making it seems that QKD is applicable to commercial communication systems. All such claims are based on a misunderstanding of the meaning of criteria of information theoretic security in cryptography. A severe situation has arisen as a result, one that will impair a healthy development of quantum information science (QIS). Thus, the author hopes that this paper will help to stimulate discussions on developing a more detailed theory.

Quantum cryptography assessing the security and practicality of quantum key distribution in modern communication networks

Abha Kiran Rajpoot, Dharmesh Dhabliya, V. N. Trupti +3 more

The increasing number of cyber threats and the approaching development of quantum computing demand a critical review of existing cryptographic approaches. The goal of this work is to evaluate the security and practicality of utilizing Quantum Key Distribution for secure communications. QKD utilizes the laws of quantum mechanics to provide a secure and unbreakable method for exchanging information. Protocols like BB84 are resistant to threatening attacks from both classical and quantum adversaries. The methodology utilizes simulated models and quantum communication toolkits to study critical characteristics such as key generation speed, QBER, latency and scalability. Performance of QKD is compared to that of classical schemes such as RSA-2048, ECC-256 and AES-256. Results reveal that although QKD provides unparalleled theoretical security, its deployment has notable obstacles such as intricate infrastructure, restrictions on distance and elevated latency. Our study reveals that optimizing the interplay between security and practicality in QKD deployment can yield a highly effective safeguard for next-generation communication networks.

The debate over QKD: A rebuttal to the NSA's objections

Renato Renner, Ramona Wolf

A recent publication by the NSA assessing the usability of quantum cryptography has generated significant attention, concluding that this technology is not recommended for use. Here, we reply to this criticism and argue that some of the points raised are unjustified, whereas others are problematic now but can be expected to be resolved in the foreseeable future.

Quantum Key Distribution for Sustainable and Secure Communication: Opportunities and Challenges

Shashank Thakur

This research paper offers an in-depth analysis of the potential benefits of quantum key distribution (QKD) to provide secure communication channels. The limitations of classical cryptography are explored in detail, highlighting the need for alternative approaches to mitigate against the growing sophistication of cyber threats. The advantages of QKD, including its absolute security and ability to detect eavesdropping, are also extensively discussed, along with successful case studies of QKD deployments and critical lessons learned from these initiatives. Despite its potential advantages, the paper also acknowledges the challenges and limitations of practically implementing QKD in its scalability, cost, interoperability, susceptibility to quantum attacks, and the importance of investment in research and development to accelerate progress in this field. Additionally, the paper examines successful implementations of QKD in real-life scenarios. The potential applications of QKD in various sectors, such as government and military, healthcare, and finance, are highlighted. The regulatory and legal challenges surrounding using QKD protocol encryption, including the need for licensing and approval, are also briefly discussed. In conclusion, the paper discusses future opportunities and challenges for quantum cryptography and QKD in achieving sustainable and secure communication and the prospects of practical implementation of QKD. To address the challenges and promote QKD deployment in sustainable communication networks, this paper recommends increasing funding for continuing QKD research and development; international collaboration between academia and industry; stakeholder engagement to ensure QKD's safe, secure, and ethical deployment; and the incentivization of QKD deployment in critical infrastructure. Additionally, governments should prioritize QKD research and education programs to create a skilled workforce in developing and deploying QKD technology. Overall, the findings of this research demonstrate the need for more research, development, and policy recommendations to enable the practical deployment of QKD in sustainable communication networks and ensure their security and resilience.

Towards efficient and secure quantum-classical communication networks

Pei Zeng, Debayan Bandyopadhyay, José A. Méndez Méndez +7 more

The rapid advancement of quantum technologies calls for the design and deployment of quantum-safe cryptographic protocols and communication networks. There are two primary approaches to achieving quantum-resistant security: quantum key distribution (QKD) and post-quantum cryptography (PQC). While each offers unique advantages, both have drawbacks in practical implementation. In this work, we introduce the pros and cons of these protocols and explore how they can be combined to achieve a higher level of security and/or improved performance in key distribution. We hope our discussion inspires further research into the design of hybrid cryptographic protocols for quantum-classical communication networks.

An Introduction to Practical Quantum Key Distribution

Omar Amer, Vaibhav Garg, Walter O. Krawec

Quantum technology, and especially quantum computing, is advancing rapidly. Our every-day secure communication infrastructure relies heavily on public key cryptography; unfortunately, many public key schemes are in fact insecure against quantum algorithms. Furthermore, adversaries who, today, capture information encrypted using classical key distribution systems, can wait and, as soon as quantum computers of sufficient power become available, they may decipher all previously captured information. While some new “post-quantum” public key systems are assumed to be secure against quantum computers, this is only an assumption and, even if the assumption remains valid, still results in systems that are less efficient for end-users than the more commonly used public key systems employed today. While the advent of quantum technology may seem detrimental to security, in fact, one may harness the power of quantum through quantum key distribution (QKD) for stronger security guarantees. Such QKD protocols allow two (or more) parties to establish a shared secret key, secure against an all-powerful adversary. Perhaps surprising is that QKD technology is already here both experimentally and commercially. This tutorial serves as an introduction to basic QKD along with QKD technology from a practical perspective. Quantum communication is a highly interdisciplinary field of research and one of the goals of this article is to introduce a larger set of researchers and practitioners to its study in the hopes of furthering its progress and eventual wide-scale adoption.
