Toward A Quantum Safe Communication Infrastructure

The accelerating pace at which quantum computing is developing makes it almost inevitable that some of the major cryptographic algorithms and protocols we rely on daily, for everything from internet shopping to running our critical infrastructure, may be compromised in the coming years. This book presents 11 papers from the NATO Advanced Research Workshop (ARW) on Quantum and Post-Quantum Cryptography, hosted in Malta in November 2021. The workshop set out to understand and reconcile two seemingly divergent points of view on post-quantum cryptography and secure communication: would it be better to deploy post-quantum cryptographic (PQC) algorithms or quantum key distribution (QKD)? The workshop brought these two communities together to work towards a future in which the two technologies are seen as complementary solutions to secure communication systems at both a hardware (QKD) and software (PQC) level, rather than being in competition with each other. Subjects include the education of an adequate workforce and the challenges of adjusting university curricula for the quantum age; whether PQC and QKD are both required to enable a quantum-safe future and the case for hybrid approaches; and technical aspects of implementing quantum-secure communication systems. The efforts of two NATO nations to address the possible emergence of cryptanalytically-relevant quantum computers are explored, as are two cryptographic applications which go beyond the basic goal of securing two-party communication in a post-quantum world. The book includes economic and broader societal perspectives as well as the strictly technical, and adds a helpful, new contribution to this conversation.

The world is waiting for the first quantum computers, which are expected to revolutionize computing. Their unprecedented power may also enable them to crack the digital encryption system upon which the modern information and communication infrastructure depends. By breaking that encryption, quantum computing could jeopardize secure communications, financial transactions, and the support system for the global economy. The authors of this report explore those risks by assessing, first, how quickly quantum computers are likely to be developed; second, how quickly encryption that can withstand attacks by quantum computers, or postquantum cryptography (PQC), is likely to be standardized; and third, how quickly and widely PQC will be adopted. The analysis concludes that the threat to the security of the modern communications infrastructure is urgent but manageable, and the authors offer recommendations to the U.S. government for responding. There is already a race among nations and corporations attempting to develop quantum computers (primarily in the United States, China, and the European Union), and many expected commercial applications are unrelated to cryptography. Quantum computers capable of undermining current cryptography are likely at least a decade off, but they are already introducing risks, and these risks will grow over time. To assess these timelines and associated risk, the authors undertook a mixed-methods approach consisting of a literature review, a review of expert opinion, and a broad consumer survey to assess the likely events, risks, and uncertainties and recommend appropriate policies and risk-mitigation actions.

Features are modifications to the control of telecommunications services. A feature interaction occurs when the behaviour of another, which can lead to unexpected or undesired behaviour, which affects the quality of service. The goal of this volume is to generate a combination of techniques through protocol engineering, software testing, formal techniques and AI and applications to telecommunications services.

Photonic Quantum Technologies Brings together top-level research results to enable the development of practical quantum devices In Photonic Quantum Technologies: Science and Applications, the editor Mohamed Benyoucef and a team of distinguished scientists from different disciplines deliver an authoritative, one-stop overview of up-to-date research on various quantum systems. This unique book reviews the state-of-the-art research in photonic quantum technologies and bridges the fundamentals of the field with applications to provide readers from academia and industry, in one-location resource, with cutting-edge knowledge they need to have to understand and develop practical quantum systems for application in e.g., secure quantum communication, quantum metrology, and quantum computing. The book also addresses fundamental and engineering challenges en route to workable quantum devices and ways to circumvent or overcome them. Readers will also find: A thorough introduction to the fundamentals of quantum technologies, including discussions of the second quantum revolution (by Nobel Laureate Alain Aspect), solid-state quantum optics, and non-classical light and quantum entanglement Comprehensive explorations of emerging quantum technologies and their practical applications, including quantum repeaters, satellite-based quantum communication, quantum networks, silicon quantum photonics, integrated quantum systems, and future vision Practical discussions of quantum technologies with artificial atoms, color centers, 2D materials, molecules, atoms, ions, and optical clocks Perfect for molecular and solid-state physicists, Photonic Quantum Technologies: Science and Applications will also benefit industrial and academic researchers in photonics and quantum optics, graduate students in the field; engineers, chemists, and computer and material scientists.

Using the quantum properties of single photons to exchange binary keys between two partners for subsequent encryption of secret data is an absolutely novel te- nology. Only a few years ago quantum cryptography – or better Quantum Key Distribution – was the domain of basic research laboratories at universities. But during the last few years things changed. Quantum Key Distribution or QKD left the laboratories and was picked up by more practical-oriented teams that worked hard to develop a practically applicable technology out of the astonishing results of basic research. One major milestone toward a QKD technology was a large research and dev- opment project funded by the European Commission that aimed at combining qu- tum physics with complementary technologies that are necessary to create a tech- cal solution: electronics, software, and network components were added within the project SECOQC (Development of a Global Network for Secure Communication based on Quantum Cryptography) that teamed up all expertise on European level to get a technology for future cryptography.

The book presents a collection of scientific research in the field of agriculture cyber-physical systems (ACPSs). The methods and tools for agricultural systems design, estimation and monitoring are proposed in this book. The book presents technical developments in the robotics and IoT sector, new solutions with drones, sensors and smart agriculture machines, solutions to digitize the farmer's life by delivering holistic management platforms and monitoring systems, as well as studies devoted to the field mapping. Research on creating a digital twin of the supply chain to predict the near-future state of the supply chain are also presented in this book. The book contains proceedings of the conference "Fundamental and Applied Scientific Research in the Development of Agriculture in the Far East" (AFE-2022, Tashkent, Uzbekistan). The book allows optimizing agricultural production, maximizes their yield and minimizes losses with efficient use of resources and decreases skilled labor.
