This book provides an overview of state-of-the-art implementations of quantum random number generators (QRNGs), and especially examines their relation to classical statistical randomness models and numerical techniques for computing random numbers. The reader - who ideally has a background in classical statistics, computer science, or cryptography - is introduced to the world of quantum bits step by step, and explicit relations between QRNGs and their classical counterparts are identified along the way. Random number generation is a major pillar of cryptography. Capitalizing on the randomness inherent in quantum phenomena is a rapidly evolving branch of quantum cryptography with countless applications for the future. The value of quantum randomness for cryptographic purposes is empirically demonstrated in statistical evaluations of QRNGs' performance compared to classical techniques for true and pseudorandom number generation. The book then provides an overview of technical implementations of QRNGs, before a concluding discussion of major achievements and remaining obstacles in the field rounds out the coverage, while also opening the door for future research directions.

The chapters in this volume explore how various methods from game theory can be utilized to optimize security and risk-management strategies. Emphasizing the importance of connecting theory and practice, they detail the steps involved in selecting, adapting, and analyzing game-theoretic models in security engineering and provide case studies of successful implementations in different application domains. Practitioners who are not experts in game theory and are uncertain about incorporating it into their work will benefit from this resource, as well as researchers in applied mathematics and computer science interested in current developments and future directions. The first part of the book presents the theoretical basics, covering various different game-theoretic models related to and suitable for security engineering. The second part then shows how these models are adopted, implemented, and analyzed. Surveillance systems, interconnected networks, and power grids are among the different application areas discussed. Finally, in the third part, case studies from business and industry of successful applications of game-theoretic models are presented, and the range of applications discussed is expanded to include such areas as cloud computing, Internet of Things, and water utility networks.

This book focuses on practical implementation details, telecommunication techniques, security and technology challenges and approaches to implementing quantum technology in modern telecommunication systems. The authors use their extensive practical academic and industrial experience in network technologies and provide details from international projects in quantum cryptography in which they actively participate. Using a variety of examples, analogies, illustrations, tables, and features from practical quantum network realizations, the authors provide a unique view of quantum technology from an engineering telecommunication standpoint, allowing the reader to identify the advantages and challenges of quantum technology. This book also addresses challenges posed by quantum technology such as network organization, passive and active eavesdropping, and future trends in QKD such as Software Defined Networking (SDN) with QKD and application QKD in 5G networks. It is conceived through eight chapters by treating the following thematic units separately: Fundamentals of Quantum Key Distribution, QoS architecture/mode, QoS MAC layer, QoS signaling techniques for key management and session negotiation purpose and QoS routing protocols that minimize the consumption of key material through the equitable utilization of network resources when finding an optimal path. Through numerous information on practical solutions, simulation examples, illustrations, and analysis, readers can easily distinguish the specificity of quantum technology and understand the challenges and methods of practical implementation of quantum cryptography in common telecommunications standards. Researchers working in quantum technology and applied networking security as well as advanced-level students studying computer science and electrical engineering will benefit from this book. Professionals working within these related fields will also benefit from this book.

This book presents a compendium of selected game- and decision-theoretic models to achieve and assess the security of critical infrastructures. Given contemporary reports on security incidents of various kinds, we can see a paradigm shift to attacks of an increasingly heterogeneous nature, combining different techniques into what we know as an advanced persistent threat. Security precautions must match these diverse threat patterns in an equally diverse manner; in response, this book provides a wealth of techniques for protection and mitigation. Much traditional security research has a narrow focus on specific attack scenarios or applications, and strives to make an attack "practically impossible." A more recent approach to security views it as a scenario in which the cost of an attack exceeds the potential reward. This does not rule out the possibility of an attack but minimizes its likelihood to the least possible risk. The book follows this economic definition of security, offering a management scientific view that seeks a balance between security investments and their resulting benefits. It focuses on optimization of resources in light of threats such as terrorism and advanced persistent threats. Drawing on the authors' experience and inspired by real case studies, the book provides a systematic approach to critical infrastructure security and resilience. Presenting a mixture of theoretical work and practical success stories, the book is chiefly intended for students and practitioners seeking an introduction to game- and decision-theoretic techniques for security. The required mathematical concepts are self-contained, rigorously introduced, and illustrated by case studies. The book also provides software tools that help guide readers in the practical use of the scientific models and computational frameworks.

Robotics is becoming more and more ubiquitous, but the pressure to bring systems to market occasionally goes at the cost of neglecting security mechanisms during the development, deployment or while in production. As a result, contemporary robotic systems are vulnerable to diverse attack patterns, and a posteriori hardening is at least challenging, if not impossible at all. This book aims to stipulate the inclusion of security in robotics from the earliest design phases onward and with a special focus on the cost-benefit tradeoff that can otherwise be an inhibitor for the fast development of affordable systems. We advocate quantitative methods of security management and design, covering vulnerability scoring systems tailored to robotic systems, and accounting for the highly distributed nature of robots as an interplay of potentially very many components. A powerful quantitative approach to model-based security is offered by game theory, providing a rich spectrum of techniques to optimize security against various kinds of attacks. Such a multi-perspective view on security is necessary to address the heterogeneity and complexity of robotic systems. This book is intended as an accessible starter for the theoretician and practitioner working in the field.

Studienarbeit aus dem Jahr 2013 im Fachbereich Politik - Sonstige Themen, Note: 1,3, Friedrich-Alexander-Universitat Erlangen-Nurnberg (Politikwissenschaften), Veranstaltung: Das politische System Indiens, Sprache: Deutsch, Abstract: Indien, insbesondere die religiose Kultur des Subkontinents, gilt im Westen als eine tolerante, multikulturelle und friedliche Gesellschaft. Der Erfolg der straff organisierten hindunationalistischen Partei BJP wurde Ende der achtziger und neunziger Jahre von der ganzen Welt umso mehr mit Besorgnis aufgenommen. Sie propagierten, gepragt von der Hindutva-Ideologie, die Hindu Rashta, eine durch Hindus kulturell dominierte Gesellschaft. Befurchtungen vor Destabilisierung, theokratischer Diktatur und einem nuklearen Krieg mit Pakistan wurden laut. Durch die Zerstorung der Babri-Moschee, die zahlreiche Menschenleben forderte, und die Ermordung Mahatma Gandhis durch einen Hindunationalisten hatte die internationale Gemeinschaft schon mehrmals ein sehr gewalttatiges Bild auf die politisch extremen Hindus bekommen. Es wurden eine weitere Eskalation und Intensivierung des Konflikts vermutet. Die indische Demokratie war augenscheinlich ins Wanken geraten. Zwei Jahrzehnte spater befindet sich die Bewegung in der Opposition und daruber hinaus in einer Sinnkrise. Die hindunationalistische Vielparteienkoalition der National Democratic Alliance hat sich in den Wahlen 2004 nicht mehr durchsetzen konnen. Diese Arbeit beschaftigt sich mit dem Erfolg der Nationalisten und den Hintergrunden des baldigen Abstiegs der zuvor aufstrebenden Bewegung, nach nur einer Legislaturperiode. Indien als Land, welches von kulturellen und ethnischen Konflikten durchzogen ist und in dem breite Bevolkerungsschichten in Armut leben, bietet eigentlich einen idealen Nahrboden fur radikales Gedankengut. Im Zuge der Modernisierung und Globalisierung tun sich immer grossere Spalten auf und die Gesellschaft ist einem radikalen Wandel unterworfen. Hindus und Muslime konkurrieren u

Facharbeit (Schule) aus dem Jahr 2011 im Fachbereich Gemeinschaftskunde / Sozialkunde, Note: 15, Gustav-von-Schlor-Schule Staatliche Fachoberschule und Berufsoberschule, Weiden, Sprache: Deutsch, Abstract: "Ihr seid jetzt also auch mit den Facebook-Kids zusammen" so begann der sogenannte Bruder Fuhrer Gadaffi ein folgeschweres Gesprach mit vier oppositionellen Juristen aus Bengasi. Dies zeigt von der Arroganz des Revolutionsfuhrers und Ignoranz der Lage in seinem eigenen Land. Denn direkt nach diesem Gesprach vereinbarten die vier Rechtsgelehrten "den 17. Februar zum Tag des Zorns auszurufen," der unter anderem ein Ausloser fur die darauf folgenden Ausschreitungen in Libyen war und ein Einschreiten der westlichen Welt nach sich zog. Mit dem Beginn des sogenannten Arabischen Fruhlings, den Revolutionen im Nahen Osten am Anfang 2011, anderte sich die Machtstruktur in der arabischen Welt grundlegend. Besonders in Libyen kam es dabei zu gewaltsamen Auseinandersetzungen zwischen der Bevolkerung und der Regierung, bei denen sich Gaddafis Militarapparat mit seiner gesamten Macht gegen die drohende Veranderung stemmte. Um die Bevolkerung zu schutzen, musste die UN handeln. Sie verhangte Sanktionen, Reiseverbote und ermoglichte die Einrichtung einer Flugverbotszone uber dem Nachbarland Agyptens. Die Vereinten Nationen sind eine weltweite Organisation, die der internationalen Friedenssicherung dient. Winston Churchill sagte einmal: "Die UNO wurde nicht gegrundet, um uns den Himmel zu bringen, sondern um uns vor der Holle zu bewahren." Dies trifft oft sehr genau auf die Missionen der Vereinten Nationen und besonders den Einsatz im Norden Afrikas zu. Aufgrund dieser aktuellen und schwerwiegenden Geschehnisse habe ich mich naher mit der UNO, ihrer Struktur, den Handlungsmoglichkeiten bei internationalen Konflikten und insbesondere ihrem Eingreifen in der Libyen-Krise beschaftigt. Des Weiteren habe ich mich mit grundlegenden Problemen der Vereinten Nationen und Kontroversen in ih
