Abstract

Quantum Key Distribution (QKD) is developed to improve the security network in key exchange field. There is several success network equipment in implement QKD. However, the key distribution is limited to use in point-to-point scope. In this paper, a network in quantum cryptography network is simulated based on actual Thailand broadband services that will extend the ability of number of users in present quantum cryptography network from point-to-point to multi-user network and sustain the security of the network. The developed system is implemented based on the existing quantum cryptography by managing the pairs joining of QKD system and real data of last-mile infrastructure and services of rural and remote broadband development in Thailand. The result of simulation is proven the feasibility to implement the proposed concept in real implementation.

In conventional security mechanism, security services based on symmetric key cryptography assume keys to be distributed prior to secure communications. The core function of exchanging and sharing a secret key between two endpoints are the secure key management methodology which is one of the most critical elements need to be more concerned when integrating cryptographic functions into the system. In case the key management mechanisms is weak can lead to the vulnerability holes or a potentially fatal outsider attacks as the harmful effects to the system. Since, there is still no standardized architecture or protocol that can provide cross application symmetric key management services. Therefore, this paper approaches a secure key management model and its custom protocols to build Thailand quantum trusted network with offers simultaneous quantum key distribution to multiple user overtime. Consequently, the proposed technique has also overcome the limitation of quantum point-to-point key sharing. Based on the discussion of key management security requirement, deal with generic key management concepts and designing the new custom protocols to close the possibility loopholes, to offers reliability and convenience of use, as well as to introduce a secure and efficient key management technique for quantum cryptography network in Thailand where any communication services can take place.

Secure communication makes the widespread use of telecommunication networks and services possible. With the constant progress of computing and mathematics, new cryptographic methods are being diligently developed. Quantum Key Distribution (QKD) is a promising technology that provides an Information-Theoretically Secure (ITS) solution to the secret-key agreement problem between two remote parties. QKD networks based on trusted relay nodes are built to provide service to a larger number of parties at arbitrary distances. They function as an add-on technology to traditional networks, generating, managing, distributing, and supplying ITS cryptographic keys. Since key resources are limited, integrating QKD network services into critical infrastructures necessitates effective key management. As a result, this article provides a comprehensive review of key management approaches for trusted-relay QKD networks. They are analyzed to facilitate the identification of potential strategies and accelerate the future development of QKD networks.

Using Quantum Key Distribution for Securing Real-Time Applications

Miralem Mehić

Quantum Key Distribution (QKD), based on the laws of physics rather than the computational \ncomplexity of mathematical problems, provides a secure way of establishing symmetrical binary \nkeys between two geographically distant users. The keys are secure from eavesdropping during \ntransmission and QKD ensures that any third party’s knowledge of the key is reduced to a \nminimum. In recent years, a noticeable progress in the development of quantum equipment has \nbeen reflected through a number of successful demonstrations of QKD technology. While they \nshow the great achievements of QKD, many practical difficulties still need to be resolved, such as \nto provide better service differentiation. These networks are characterized as being multihop in \nnature where the consumption key rate is often higher than the charging key rate, which means that \nthe links are available for a limited period of time only. Such features impose several challenges \non the effective modeling and evaluation of reliability as well as finding appropriate Quality \nof Service (QoS) solution. This thesis focuses on research in the field of QKD for securing \nreal-time communication by supporting QoS in QKD networks including a novel QoS model \nand novel distributed reactive routing protocol to achieve high-level scalability and minimize the \nconsumption of key material used for securing routing data. \nAs research in QKD networks grows larger and more complex, the need for highly accurate and \nscalable simulation technologies becomes important to assess the practical feasibility and foresee \ndifficulties in the practical implementation of theoretical achievements. Due to the specificity of \nQKD link which requires optical/quantum and Internet connection between the network nodes, it \nis very costly to deploy a complete testbed containing multiple network hosts and links to validate \nand verify a certain network algorithm or protocol. The network simulators in these circumstances \nsave a lot of money and time in accomplishing such task. A simulation environment offers the \ncreation of complex network topologies, a high degree of control and repeatable experiments, \nwhich in turn allows researchers to conduct exactly the same experiments and confirm their results. \nThis thesis describes the design and implementation of QKD network simulation module which \nwas developed in the network simulator of version 3 (NS-3). The module supports simulation \nof QKD network in overlay mode or in a single TCP/IP mode. Therefore, it can be used for \nsimulation of other network technologies regardless of QKD. \nImplemented simulation model was used for verification of proposed QoS solution. A number \nof simulations were performed. The obtained data have confirmed the primary thesis of this study, \nthat it is possible to use real-time applications in QKD networks.

Large-scale quantum key distribution network simulator

Emir Dervisevic, Miroslav Vozn̆ák, Miralem Mehić

The wide range of supported services in modern telecommunication networks has increased the demand for highly secure means of communication. Common security frameworks based on the computational security model are expected to become insecure due to significant advances in quantum computing. Quantum key distribution (QKD), a new secret key agreement primitive, enables long-anticipated practical information-theoretical security (ITS). Over the past two decades, academic and industrial communities have devoted their time and resources to developing QKD-based networks that can distribute and serve ITS keys to remote parties. However, because the availability of QKD network testbeds to the larger research community is limited and the deployment of such systems is costly and difficult, progress in this area is noticeably slow. To address this problem and spur future development and education, we provide a valuable, unique tool for simulating a QKD network. The tool is essential to testing novel network management methodologies applied to large-scale QKD networks. The simulator model contained in the tool was validated by simulating a network with six nodes and three pairs of users. The results indicate that the designed functional elements operate correctly.
