A quantum key distribution (QKD) network is proposed to allow QKD protocols to be the infrastructure of the Internet for distributing unconditional security keys instead of existing public-key cryptography based on computationally complex mathematical problems. Numerous countries and research institutes have invested enormous resources to execute correlation studies on QKD networks. Thus, in this study, we surveyed existing QKD network studies and practical field experiments to summarize the research results (e.g., type and architecture of QKD networks, key generating rate, maximum communication distance, and routing protocol). Furthermore, we highlight the three challenges and future research issues in the security of QKD networks and then provide some feasible resolution strategies for these challenges.

The aim of this chapter is to emphasize the multidisciplinary nature of the research in the field of Quantum Key Distribution Networks (QKDNs). Such networks consist of a number of nodes that can perform security protocols protected by some basic laws of physics. The operation of QKDNs mainly requires the integration of Quantum Key Distribution (QKD) protocols with the already-existing network security infrastructures. The authors report on the current state-of-the-art in the field and give some recommendations for future research. As computer simulation can be very useful in dealing with advanced technology subjects like QKDNs, they outline a simple and efficient modeling and simulation approach for various QKDN configurations. Then, the issue of unconditionally secure authentication of the public channel in QKD is considered. This issue is of crucial importance from both theoretical and practical sides. In this context, the proposed hybrid authentication strategy is reviewed and an authenticated version of the Bennett-Brassard-84 (BB84) QKD protocol based on this strategy is described. Next, a novel extension of the SSL protocol for QKDN settings, which the authors call Quantum SSL (QSSL), is explained. Finally, the chapter is concluded.

Quantum key distribution (QKD) is the objects of close attention and rapid progress due to the fact that once first quantum computers are available – classical cryptography systems will become partially or completely insecure. The potential threat to today’s information security cannot be neglected, and efficient quantum computing algorithms already exist. Quantum cryptography brings a completely new level of security and is based on quantum physics principles, comparing with the classical systems that rely on hard mathematical problems. The aim of the article is to overview QKD and the most conspicuous and prominent QKD protocols, their workflow and security basement. The article covers 17 QKD protocols and each introduces novel ideas for further QKD system improvement.
