Book SynopsisHow to solve security issues and problems arising in distributed systems. Security is one of the leading concerns in developing dependable distributed systems of today, since the integration of different components in a distributed manner creates new security problems and issues. Service oriented architectures, the Web, grid computing and virtualization form the backbone of today's distributed systems. A lens to security issues in distributed systems is best provided via deeper exploration of security concerns and solutions in these technologies. Distributed Systems Security provides a holistic insight into current security issues, processes, and solutions, and maps out future directions in the context of today's distributed systems. This insight is elucidated by modeling of modern day distributed systems using a four-tier logical model host layer, infrastructure layer, application layer, and service layer (bottom to top).

Book SynopsisWe are at the threshold of a new area of the internet that promises to transform the way we engage financially and take the power of data and privacy back from big corporations and give it to the individual through decentralization. This is sometimes called Web 3.0. While Web 1.0 transformed information sharing and commerce and brought us giants like Google and Amazon and Web 2.0 unlocked the social potential of the internet and created Facebook, Twitter, and Snapchat, exactly what will come of Web 3.0 remains to be seen. It is indisputable that the seed of Web 3.0 is the technological, social, and economic innovations that came together in Bitcoin and the blockchain technology it created. But where the first web iterations were relatively straightforward to understand, the inner workings of Web 3.0 remain more opaque and shrouded in mystique. Current voices on Bitcoin and the blockchain revolution fall squarely into one of two camps; either technological experts who are all also invTable of ContentsIntroduction Part 1 - Genealogy of bitcoin technology The technological developments leading to bitcoin. This part is a technological history that reviews the technological developments that Bitcoin builds on. There are a few strands that developed more or less independently that combine into Bitcoin. Once they are explained it is possible to give a deeper explanation of how Bitcoin works. This understanding will inform the remaining parts of the book. Chapter 1: Cryptography The purpose of cryptography is to keep information private by preserving confidentiality, integrity and access to it. Public private key encryption Hashing Zero knowledge proof Chapter 2: Virtual Money In this chapter we will go into the history of electronic or virtual money before bitcoin. Digicash E gold Bitgold b Money Hash cash Chapter 3: Peer-to-peer technology The internet of today is a centralized type of computing working through a number of web servers that function in a hierarchy. Properties of p2p networks Discovering a peer Secure sharing File Sharing from Napster to BitTorrent Chapter 4: Proof of work An inherent problem with the networked world is that accessing and processing information is essentially free, which makes certain types of disruptive behavior easy, which we see in denial of service attacks, spam mail and robocalling. This brings new problems that did not exist when it cost significant money to send a letter, read a paper or book or make a phone call. DDoS Spam Money transactions Chapter 5: Public record Since the time of the code of Hammurabi, the purpose of a public record has been clear: to establish indisputable truth. While this is seemingly the opposite of the privacy and confidentiality entailed by cryptography it serves the purpose of making information shared and immutable. Historical technologies of public record The purpose of public records The accounting revolution and the development of ledgers, double entry bookkeeping to triple entry bookkeeping Chapter 6: Bitcoin From the previous chapters we are now able to piece together how bitcoin and the block chain works. Virtual money - The Bitcoin Encrypting for privacy - The Wallet Public record - The Blockchain Peer to peer network - The Miners Proof of work - Transactions (cryptographic proof and the consensus algorithm) Part 2 - Still searching for Satoshi - who is the historical Satoshi Nakamoto? Much writing about Bitcoin has focused on who the historical person or persons behind Satoshi Nakamoto is. This part will apply a historical critical perspective to this question and sift through the evidence in order to create a better understanding of what we can and cannot say about the identity of Satoshi Nakamoto. Chapter 7: Who dunnit? A review of previous identifications of the person behind Satoshi. This has previously taken the shape of investigative journalism in the style of true crime reporting Joshua Davis, The New Yorker 2011 Adam Penenberg, Fast Company 2011 Alec Liu, Vice 2013 John Markoff, New York Times 2013 Andy Greenberg, Forbes 2014 Leah McGrath Goodman, Newsweek 2014 Skye Grey, blog 2014 Dominic Frisby, Bitcoin the future of money 2014 Nathaniel Popper, New York Time 2015 Andy Greenberg, Gwern Branwen, Wired 2015 Sam Biddle, Gizmodo 2015 Izabella Kasminska, Financial Times 2016 Evan Ratliff, Wired 2019 Other sources - twitter, youtube, tv Chapter 8: Ad fontes-What do the sources say? By focusing on the sources we are able to extract a number of key characteristics to look for: Historical analysis - establishes a couple of key points for historical analysis The bitcoin whitepaper - the most crucial piece of evidence The forums - the p2p forum and later the bitcoin forum are sources where Satoshi discussed with peers about bitcoin The code - the code in itself may also contain clues The blockchain - the record of transactions also provides an insight into the origin of bitcoin Summary - what can the sources tell us? Chapter 9: Motives What were the motives behind the creation of bitcoin Ideology - what can be said about the ideology of the author based on extant sources? Why the synonym? - what could be the reason for the initial and continued secrecy surrounding the inventor? Summary - why did the inventor invent bitcoin and in this particular way? Chapter 10: The social network of early bitcoin Who were the people involved in the beginning of Bitcoin p2p forum communication Bitcoin forum communication Blockchain transactions Summary - what can we learn from looking at the bitcoin initial network Chapter 11: The usual suspects? Rather than pointing definitively to one or another suspect we will try to integrate the knowledge we have gained with the list of known suspects. An evaluation framework - developing an evaluation framework against which to measure the likelihood of any candidate being Satoshi Nakamoto Prime suspects - the suspects that have gained most attention · Hal Finney · Nick Szabo · Dorian Sakamoto · Craig Wright and David Kleiman · Paul Leroux Secondary suspects - suspects that have gained some attention · Vili Lehdonum and Michael Clear · Neal King, Vladimir Oksman, Charles Bry · Hal Finney, Nick Szabo and Adam Back · Shinichi Mochizuki · Ross Ulbricht · Adam Back · Gavin Andresen · Jed McCaleb · Elon Musk · Len Sassaman · Someone else A new primary suspect - as in the movie The Usual Suspects, careful analysis points towards a surprising suspect who is not in the primary field of suspects. Part 3 - Bitcoin in context How is bitcoin viewed in the wider context of human civilization? Bitcoin does not exist in a technological bubble addressing only technological issues. It is firmly situated in a web of themes that are and have been central to human civilization. This may account for its notoriety but needs to be put in context. Chapter 12: Money Since prehistoric times humans have engaged in exchange. This falls in a continuum from barter, through intermediaries as cowry shells, gold and silver coins to purely symbolic means of exchange. The history of money Medium of exchange Unit of account Standard of deferred payment Store of value Types of money · Commodity · Representative money · Fiat · Digital money · Deposits The politics of money Money as a bridge between domains of value Chapter 13: Ownership Proving that you own something has been a central feature of human societies for millenia and disputes have fueled more than its share of violence and conflict. Owners · Private · Public · Corporate · Communal Property · Tangible · Intangible Establishing and policing ownership · National · Transnational Chapter 14: Social organization Human societies have always been characterized by some sort of social organization. The different options have been debated since classical antiquity. This chapter will take a look at the space of social organization and narrow it down to the particular types associated with bitcoin and blockchain. An ancient discussion: Monarchy, Oligarchy and Democracy - and anarchy Centralization vs decentralization Types of social organization in human groups Open source Cypher punks Chapter 15: Religion A rarely debated issue are the religious aspects surrounding Bitcoin and the blockchain movement. But these aspects are nothing new when it comes to human cultures. Understanding this helps explain a lot of the seemingly strange behavior of bitcoin believers without claiming that Bitcoin is an actual religion. The prophet - Satoshi Nakamoto Sacred scriptures- The Bitcoin whitepaper and the forum posts Believers and heathens Cargo cults Millenarianism Part 4 - Blockchain and the future Where can blockchain technology be applied? Where, if anywhere, might we see cryptocurrencies and the blockchain in the future and how might it affect our lives? A case could be made that we are only in the beginning phases of the blockchain now, sometimes called Web3, where the worst of the teething problems are gone and the wild west ethos is receding. Where not to use blockchain - First let us consider a number of areas where blockchain is currently suggested that might not be particularly relevant. Parameters to be tweaked - Bitcoin was the first version of blockchain technology and certain choices were made. But subsequent and future blockchains need not make the same choices. We need to understand how this can be done in order to ascertain the future utility of the blockchain. Transaction speed Energy consumption Degree of centralization Public availability Mining rewards Banking - even though Bitcoin at its outset was antithetical to the banking industry there are particularly good use cases here. Payment - bitcoin may not in itself have been very successful as a payments solution so far but there is no reason why another cryptocurrency will not be. Current payment systems are slow and expensive compared to what the blockchain can offer. International payments Remittance Peer to peer payments Micropayments Certification - building on the ability to serve as a public record there are good reasons that a blockchain can serve as a public record for information about ownership NFTs Real estate Media Contracts - the ability to establish indisputable truth makes it possible to build contracts that automatically execute according to some logic. This can be used for escrow services and delivery of other services as well as insurance. Regulatory compliance - the immutability of the blockchain makes it good for a great number of use cases where fraud has previously been an issue Forensics - the public nature of the blockchain makes it a valuable tool for law enforcement, especially international law enforcement, which has already proven its worth in a number of high profile cases. Supply chain - the blockchain is well suited for keeping track of things movement across time and place. Health - keeping track of health trackers and personal health records could be done on a blockchain Government - in government there are also areas where blockchain may be useful Special purpose tokens Voting Identity Glossary Key concepts described

Book SynopsisThe aim of cryptography is to design primitives and protocols that withstand adversarial behavior. Information theoretic cryptography, how-so-ever desirable, is extremely restrictive and most non-trivial cryptographic tasks are known to be information theoretically impossible. In order to realize sophisticated cryptographic primitives, we forgo information theoretic security and assume limitations on what can be efficiently computed. In other words we attempt to build secure systems conditioned on some computational intractability assumption such as factoring, discrete log, decisional Diffie-Hellman, learning with errors, and many more.In this work, based on the 2013 ACM Doctoral Dissertation Award-winning thesis, we put forth new plausible lattice-based constructions with properties that approximate the sought after multilinear maps. The multilinear analog of the decision Diffie-Hellman problem appears to be hard in our construction, and this allows for their use in cryptography. These constructions open doors to providing solutions to a number of important open problems.Table of Contents Introduction Survey of Applications Multilinear Maps and Graded Encoding Systems Preliminaries I: Lattices Preliminaries II: Algebraic Number Theory Background The New Encoding Schemes Security of Our Constructions Preliminaries III: Computation in a Number Field Survey of Lattice Cryptanalysis One-Round Key Exchange Generalizing Graded Encoding Systems Bibliography Author's Biography

Book SynopsisBy the year 2000, a balance was sought between security requirements and a respect for privacy, as well as for individual and collective freedoms. As we progress further into the 21st century, however, security is taking precedence within an increasingly controlled society.This shift is due to advances in innovative technologies and the investments made by commercial companies to drive constant technological progress. Despite the implementation of the General Data Protection Regulation (GDPR) within the EU in 2018 or 2020’s California Consumer Privacy Act (CCPA), regulatory bodies do not have the ability to fully manage the consequences presented by emerging technologies. Security and Its Challenges in the 21st Century provides students and researchers with an international legal and geopolitical analysis; it is also intended for those interested in societal development, artificial intelligence, smart cities and quantum cryptology.Table of ContentsIntroduction ix Chapter 1 Security: Actors and Rights 1 1.1 Numerous actors 1 1.1.1 Nation-states 1 1.1.2 Multinationals 3 1.1.3 The GAFAM 9 1.2 Rights and security 10 1.2.1 The law of armed conflict 10 1.2.2 Environmental law 16 Chapter 2 Interceptions 25 2.1 International interceptions 25 2.1.1 Interceptions in the 20th century 25 2.1.2 Interceptions in the 21st century 27 2.2 Interceptions in France 37 2.2.1 The 1991 law 38 2.2.2 The law of March 9, 2004 41 2.2.3 The 2015 Intelligence Act 42 2.2.4 Reform of the code of criminal procedure 52 Chapter 3 Geolocation and Video Protection 59 3.1 International standards for both geolocation and video protection/video surveillance 59 3.1.1 Comparative legal issues in the era of geolocalization 59 3.1.2 Belgian legislation on geolocation 61 3.1.3 Video surveillance/video protection 63 3.2 France 67 3.2.1 The legislative and regulatory framework 67 3.2.2 The case law just before the LOPPSI 2 and the Jean-Marc Philippe establishments 69 3.2.3 The entry into force of the LOPPSI 2 74 3.2.4 Jurisprudence after LOPPSI 2 74 3.2.5 Video protection and terrorism 88 Chapter 4 Biometrics or “the Second Circle” 89 4.1 Biometrics and international law 90 4.1.1 The United States: a historical outline 90 4.1.2 Standardization 93 4.1.3 The European Union and biometrics 94 4.2 France 98 4.2.1 Visa control 98 4.2.2 Passports 99 4.2.3 The TES database 101 4.2.4 Setting up Alicem 117 4.3 Facial recognition at the heart of globalization 119 Chapter 5 Personal Data in the United States and Europe 121 5.1 The United States and the protection of personal data in the European Union: Directive 95/46 122 5.1.1 Sensitive data 122 5.1.2 The right of access 123 5.1.3 Security 123 5.1.4 The directive of December 15, 1997, followed by the directive of July 12, 2002 and supplemented by the directive of November 25, 2009 124 5.1.5 Geolocalization 125 5.1.6 Cookies 125 5.2 The GDPR 126 5.2.1 Consent 127 5.2.2 Metadata and the “Privacy” bill 134 5.3 Cloud computing 138 5.3.1 Definition 138 5.3.2 The Safe Harbor Principles agreement 139 5.3.3 Privacy Shields 140 5.3.4 Two models 140 Chapter 6 Cybersecurity and Privacy 145 6.1 Cybersecurity itself 146 6.1.1 Cybersecurity in the United States 146 6.1.2 Cybersecurity in China 147 6.1.3 Cybersecurity in Japan 147 6.1.4 Cybersecurity and the European Union 148 6.1.5 Cybersecurity in the United Kingdom 149 6.1.6 Cybersecurity in France 149 6.1.7 The dangers of cyber-attacks 151 6.1.8 Two interesting cases 154 6.2 Cybersecurity and cryptology 158 6.2.1 Cryptology: the science of secrecy 158 6.2.2 Risks 161 6.3 PNR data 164 6.3.1 Element of definition 164 6.3.2 PNR data and nation-states 166 6.4 Smart cities 179 6.4.1 The development of standardization and certification 181 6.4.2 Strategies and CSIRTs 182 Chapter 7 Security Instruments in Texts Relating to Terrorism 185 7.1 Security instruments 185 7.1.1 The millimeter-wave scanner 185 7.1.2 The body camera 196 7.1.3 UAVs: a dual use – military and civilian 202 7.2 Standards in relation to terrorism 208 7.2.1 The law of 2014 209 7.2.2 The law strengthening internal security and the fight against terrorism 219 Chapter 8 Security and Democracy 225 8.1 Fake news 226 8.1.1 The definition 227 8.1.2 Obligations 227 8.2 Hate speech 237 8.2.1 The report 237 8.2.2 The proposed new mechanism 239 Conclusion 245 References 249 Index 251

Book SynopsisArchiving has become an increasingly complex process. The challenge is no longer how to store the data but how to store it intelligently, in order to exploit it over time, while maintaining its integrity and authenticity. Digital technologies bring about major transformations, not only in terms of the types of documents that are transferred to and stored in archives, in the behaviors and practices of the humanities and social sciences (digital humanities), but also in terms of the volume of data and the technological capacity for managing and preserving archives (Big Data). Archives in The Digital Age focuses on the impact of these various digital transformations on archives, and examines how the right to memory and the information of future generations is confronted with the right to be forgotten; a digital prerogative that guarantees individuals their private lives and freedoms.Table of ContentsPreface ix Introduction xi Chapter 1.

Book SynopsisThe study of cyberspace is relatively new within the field of social sciences, yet interest in the subject is significant. Conflicts, Crimes and Regulations in Cyberspace contributes to the scientific debate being brought to the fore by addressing international and methodological issues, through the use of case studies.This book presents cyberspace as a socio-technical system on an international level. It focuses on state and non-state actors, as well as the study of strategic concepts and norms. Unlike global studies, the socio-technical approach and “meso” scale facilitate the analysis of cyberspace in international relations. This is an area of both collaboration and conflict for which specific modes of regulation have appeared.Table of ContentsIntroduction Xi Sébastien-Yves Laurent Chapter 1 The United States, States And The False Claims Of The End Of The Global Internet 1 Sébastien-Yves Laurent 1.1 Introduction 1 1.2 The Creation Of The Internet And The Development Of Cyberspace By The United States 2 1.2.1 The First International Telecommunications Systems Developed By All States 3 1.2.2 The Creation And Development Of The Internet By The United States 3 1.2.3 International Management Controlled By The United States 4 1.2.4 A Sociotechnical System Bearing A Composite American Ideology 10 1.2.5 The False Recomposition Of The Global Sociotechnical System: The Global Summits On The Information Society 11 1.3 Cyberspace Transformed By The Arrival In Force Of States 13 1.3.1 State Intentions In “National Strategies”: A Global Approach 14 1.3.2 Russian–American Structural Disagreements On Information Security And Cybersecurity 16 1.3.3 Discussions On Cybersecurity: The Symbolic International Restoration Of The Coercive State 18 1.4 Praxis Of State Coercion In Cyberspace 20 1.4.1 Intelligence And Surveillance Activities In The Digital Environment 21 1.4.2 Non-Military Cyber Operations 24 1.4.3 Interstate Digital Conflicts, Secrecy And Coercive Diplomacy 26 1.5 The Fragmentation Of The Global Internet And The Digital Sovereignty Of States 29 1.5.1 Linguistic Balkanization: Digital Babel 29 1.5.2 Political Fragmentation: Alternative Internets 31 1.6 The Strong Constraint Of Interstate Cooperation For All States 33 1.6.1 Interstate Agreements On An Embryo Of International Law 33 1.6.2 State Dependence On International Cooperation For Cybersecurity 34 1.7 Conclusion 35 1.8 References 36 Chapter 2 Cybersecurity In America: The US National Security Apparatus And Cyber Conflict Management 43 Frédérick Gagnon and Alexis Rapin 2.1 Introduction 43 2.2 Societal And Institutional Dynamics 45 2.3 Organizational And Bureaucratic Dynamics 49 2.4 Individual Dynamics 53 2.5 Conclusion 57 2.6 References 58 Chapter 3 Separation Of Offensive And Defensive Functions: The Originality Of The French Cyberdefense Model Called Into Question?

Book SynopsisSmart homes use Internet-connected devices, artificial intelligence, protocols and numerous technologies to enable people to remotely monitor their home, as well as manage various systems within it via the Internet using a smartphone or a computer. A smart home is programmed to act autonomously to improve comfort levels, save energy and potentially ensure safety; the result is a better way of life. Innovative solutions continue to be developed by researchers and engineers and thus smart home technologies are constantly evolving. By the same token, cybercrime is also becoming more prevalent. Indeed, a smart home system is made up of connected devices that cybercriminals can infiltrate to access private information, commit cyber vandalism or infect devices using botnets. This book addresses cyber attacks such as sniffing, port scanning, address spoofing, session hijacking, ransomware and denial of service. It presents, analyzes and discusses the various aspects of cybersecurity as well as solutions proposed by the research community to counter the risks. Cybersecurity in Smart Homes is intended for people who wish to understand the architectures, protocols and different technologies used in smart homes.Table of ContentsChapter 1 Home Automation

Book SynopsisPublic key cryptography was introduced by Diffie and Hellman in 1976, and it was soon followed by concrete instantiations of public-key encryption and signatures; these led to an entirely new field of research with formal definitions and security models. Since then, impressive tools have been developed with seemingly magical properties, including those that exploit the rich structure of pairings on elliptic curves. Asymmetric Cryptography starts by presenting encryption and signatures, the basic primitives in public-key cryptography. It goes on to explain the notion of provable security, which formally defines what "secure" means in terms of a cryptographic scheme. A selection of famous families of protocols are then described, including zero-knowledge proofs, multi-party computation and key exchange. After a general introduction to pairing-based cryptography, this book presents advanced cryptographic schemes for confidentiality and authentication with additional properties such as anonymous signatures and multi-recipient encryption schemes. Finally, it details the more recent topic of verifiable computation.Table of ContentsForeword xi David POINTCHEVAL Chapter 1 Public-Key Encryption and Security Notions 1 Nuttapong ATTRAPADUNG and Takahiro MATSUDA 1.1.

Book SynopsisThis thought-provoking book challenges the way we think about the regulation of cryptoassets based on cryptographic consensus technology. Bringing a timely new perspective, Syren Johnstone critiques the application of a financial regulation narrative to cryptoassets, questions the assumptions on which it is based, and considers its impact on industry development.Providing new insights into the dynamics of oversight regulation, Johnstone argues that the financial narrative stifles the 'New Prospect' for the formation of novel commercial relationships and institutional arrangements. The book asks whether regulations developed in the 20th century remain appropriate to apply to a technology emerging in the 21st, suggesting it is time to think about how to regulate for ecosystem development. Johnstone concludes with proposals for reform, positing a new framework that facilitates industry aspirations while remaining sustainable and compatible with regulatory objectives.Rethinking the Regulation of Cryptoassets will be an invaluable read for policy makers, regulators and technologists looking for a deeper understanding of the issues surrounding cryptoasset regulation and possible alternative approaches. It will also be of interest to scholars and students researching the intersection of law, technology, regulation and finance.Trade Review‘Prof. Johnstone’s book on the regulation of cryptoassets forces us to think twice about the way we try to regulate the digital economy. He challenges the habit of the regulators to push new disruptive ideas and instruments into old frames and concepts, and invites them to move out of their comfort zone. Rethinking the Regulation of Cryptoassets is a complete account of the challenges we face in developing a crypto-economy and proposes a coherent and sustainable regulatory framework that ensures both market efficiency and technological relevance.’ -- Eva Kaili, Chair of the STOA Committee, Rapporteur of the Blockchain Resolution of the European Parliament, Brussels‘Cryptographic consensus technology presents extraordinary market opportunities but also raises a host of vexing regulatory challenges. Rethinking the Regulation of Cryptoassets maps this complex terrain and charts a way forward, offering a novel approach to the regulatory enterprise to protect against abuses while fostering innovation. Johnstone brings considerable legal, financial, and technological sophistication to the task, and his analysis is at once rigorous and accessible. This book will become essential reading on the future of cryptoassets.’ -- Christopher Bruner, University of Georgia School of Law, US‘The crypto industry moves fast and requires regulatory frameworks that can cater to that pace. Prof. Johnstone brings forward a number of ideas that are worth reflecting on as crypto assets are definitely here to stay.’ -- Henri Arslanian, Global Crypto Leader and Partner, PwC‘Johnstone provides a refreshing way to think about the regulatory limits of applying the standard financial narrative to a technology that is globally programmable but locally valuable. His DBA (Determined-By-Architecture) framework may help align regulation with the borderless possibilities of mathematics.’ -- Pindar Wong, Chairman, VeriFi (Hong Kong) LtdTable of ContentsContents: About the author Foreword Preface Why cryptoasset regulation needs rethinking: an introduction PART I THE INITIAL JOURNEY Acquiring the tradition 2 Cypher fundamentals 3 Responses from the centre PART II THE PRIMARY ISSUES 4 Applying securities laws to cryptoassets 5 Regulatory building blocks and other concerns 6 Complexities in a developing technology PART III THE SECONDARY MARKET 7 An emerging market 8 Cryptoexchange models 9 The concept of an exchange 10 Regulatory concerns PART IV INFLUENCES AND CONSIDERATIONS 11 The ordering of progress 12 Ecosystem development 13 Incrementalism and paradigms PART V FUTURE DIRECTIONS 14 Responding to change 15 Proposals for policy development 16 The origin of cryptocommunity Suggested readings Postscript Index

Book SynopsisIn The Political Economy and Feasibility of Bitcoin and Cryptocurrencies Spencer J. Pack brings his authority as a scholar and advisor to this study of bitcoin and cryptocurrencies from the perspective of the history of economic thought. Major theorists analyzed in depth include Aristotle, Smith, Law, Marx, Keynes, Rothbard and Hayek, and the book draws extensively upon the ideas of Schumpeter, Galbraith and Sraffa.The book argues for reconceptualization of the basic microeconomic categories into rental, sale and financial asset prices along with a reconsideration of Keynes’ general theory to his special theory and Rothbard’s relationship to Rousseau. The author posits that intense theoretical and practical struggles will continue over who should control the quantity of money, the cause of the capitalist economy’s instability, and who or what is more dangerous: concentrated centers of private wealth and private enterprises or the contemporary state. He concludes that in terms of the quality of money, the cryptocurrency community is probably correct, with new forms of money potentially being better than sovereign fiat currency.The book’s relevance will appeal to members of the history of economic thought community, economic theorists, and political science and political theory scholars as well as to policy makers and members of the cryptocurrency community.Trade Review‘At a time when the history of economic thought is unfortunately neglected, it is refreshing to see this book in which Spencer Pack deals brilliantly with a critical contemporaneous and practical issue from the perspective of the history of economic thought. The analysis fills a big gap in the literature on bitcoin and cryptocurrencies.’ -- Imad Moosa, RMIT, AustraliaTable of ContentsContents: Preface PART I ESSENTIAL FOUNDATIONS: BEFORE THE FRENCH REVOLUTION 1.

Book SynopsisThe end of the 20th century witnessed an information revolution that introduced a host of new economic efficiencies. This economic change was underpinned by rapidly growing networks of infrastructure that have become increasingly complex. In this new era of global security we are now forced to ask whether our private efficiencies have led to public vulnerabilities, and if so, how do we make ourselves secure without hampering the economy. In order to answer these questions, Sean Gorman provides a framework for how vulnerabilities are identified and cost-effectively mitigated, as well as how resiliency and continuity of infrastructures can be increased. Networks, Security and Complexity goes on to address specific concerns such as determining criticality and interdependency, the most effective means of allocating scarce resources for defense, and whether diversity is a viable strategy. The author provides the economic, policy, and physics background to the issues of infrastructure security, along with tools for taking first steps in tackling these security dilemmas. He includes case studies of infrastructure failures and vulnerabilities, an analysis of threats to US infrastructure, and a review of the economics and geography of agglomeration and efficiency. This critical and controversial book will garner much attention and spark an important dialogue. Policymakers, security professionals, infrastructure operators, academics, and readers following homeland security issues will find this volume of great interest.Trade Review'The world is growing more interconnected every day, spun with fiber optic cable, electric power lines, transportation and water networks. Gorman provides a detailed analysis of the pattern of telecommunications networks and their interrelationships with other infrastructure. The work is truly interdisciplinary in scope, and provides planners, policy makers, security analysts, and infrastructure managers and educators in all of these fields with an invaluable resource in terms of a rich database, a methodology, and process for assembling, analyzing and portraying information on key infrastructure assets. This work emphasizes space and place in understanding interconnectivity of physical infrastructure, integrating policy and geography as well as providing an important complement to engineering approaches to interconnected infrastructure. He presents the readers with a broad set of questions and how they can be addressed about threats, risk and vulnerability and policy options for their reduction. This is a rare book of its kind, and joins a growing literature on how complexity is a key factor in understanding and setting policies for the services upon which our society depends.' -- Rae Zimmerman, New York University, US'The concepts of Critical Infrastructure Protection are radically redefining the relationship between the public and private sectors in terms of both our national and economic security. Networks, Security and Complexity is a worthy contribution in defining and advancing many of these concepts. The author is among the vanguard of rising young scholars who will assist this nation in thinking through the significant security challenges faced in the age of information and asymmetric threat.' -- John A. McCarthy, George Mason University School of Law, US'This volume on complex networks opens surprising perspectives for the interested reader, either a scientist or a policymaker. It describes and analyzes in a convincing way the significance of critical infrastructures, be it internet or transport connections. Due insight into the existence and emergence of such infrastructures is a prerequisite for an effective security policy. This study presents a model-based, operational framework for identifying critical domains in dynamic networks. The various concepts are illustrated by means of empirical case examples.' -- Peter Nijkamp, VU University Amsterdam, The NetherlandsTable of ContentsContents: 1. Setting the Stage 2.

Book SynopsisCybersecurity could be defined as, beginning of the concept of trust and belief in cyber transactions. The era of computing began in the 20th century, with an enormous investment on computational research. Software programing languages were the foundational blocks of history of computing. Progressive research then led to networking, bringing about the formation of connectivity. Along with these creations, there was an accompanying factor of compromise on data privacy and hacking of data. This factor was the introduction to cyber security.This book is primarily created for the objective of knowledge sharing and knowledge-enabling on the conceptual ideologies of the cybersecurity. This book is aimed at students, early-career researchers, and also advanced researchers and professionals. The case studies described in the book create renewed knowledge on the innovations built on the applied theories of cybersecurity. These case studies focus on the financial markets and space technologies.
