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 term ''spyware'' is not well defined. Generally it is used to refer to any software that is downloaded onto a person''s computer without their knowledge. Spyware may collect information about a computer user''s activities and transmit that information to someone else. It may change computer settings, or cause ''pop-up'' advertisements to appear (in that context, it is called ''adware''). Spyware may redirect a Web browser to a site different from what the user intended to visit, or change the user''s home page. A type of spyware called ''keylogging'' software records individual keystrokes, even if the author modifies or deletes what was written, or if the characters do not appear on the monitor. Thus, passwords, credit card numbers, and other personally identifiable information may be captured and relayed to unauthorised recipients. Some of these software programs have legitimate applications the computer user wants. They obtain the moniker ''spyware'' when they are installed surreptitiously, or perform additional functions of which the user is unaware. Users typically do not realise that spyware is on their computer. They may have unknowingly downloaded it from the Internet by clicking within a website, or it might have been included in an attachment to an electronic mail message (e-mail) or embedded in other software. According to a survey and tests conducted by America Online and the National Cyber Security Alliance, 80% of computers in the test group were infected by spyware or adware, and 89% of the users of those computers were unaware of it. The Federal Trade Commission (FTC) issued a consumer alert on spyware in October 2004. It provided a list of warning signs that might indicate that a computer is infected with spyware, and advice on what to do if it is. This new book helps shed light on this insidious nightmare created by members of the human race to wreck havoc on the remainder.

To be successful, you need to know how toput theory into action, understand why "best practices" are the best, and know when to go rogue and break the unbreakable rules.Trade Review“An incredible book to learn the craft of software development through a new perspective: One thatis not fuelled by religion or blind following of best practices, but one that actively challenges best practices and thus requires you to think about their prosand cons.!” Sebastian Felling “This is like having a mentor in a book who is sharing all their mistakes and notes on what they've learned in a nice little package.“ Joseph Perenia “A fun, broad, anddeep conversation with an experienced programmer about coding, packed withpractical advice.” Adail Retamal “I wish I couldread this book several years ago, thus, I could have saved a lot of time.” XuYang “Contains the pragmatism an experienced software developer has gained over the years of being at the trenches (or streets as he prefers to call it).” Orlando MéndezMorales “Great book for thenew and used, self-taught, formally educated, and otherwise curious programmers doing dirt -aka street coders.” Robert Wilk

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 SynopsisAre you working on a codebase where cost overruns, death marches, and heroic fights with legacy code monsters are the norm? Battle these adversaries with novel ways to identify and prioritize technical debt, based on behavioral data from how developers work with code. And that's just for starters. Because good code involves social design, as well as technical design, you can find surprising dependencies between people and code to resolve coordination bottlenecks among teams. Best of all, the techniques build on behavioral data that you already have: your version-control system. Join the fight for better code! Use statistics and data science to uncover both problematic code and the behavioral patterns of the developers who build your software. This combination gives you insights you can't get from the code alone. Use these insights to prioritize refactoring needs, measure their effect, find implicit dependencies between different modules, and automatically create knowledge maps of your system based on actual code contributions. In a radical, much-needed change from common practice, guide organizational decisions with objective data by measuring how well your development teams align with the software architecture. Discover a comprehensive set of practical analysis techniques based on version-control data, where each point is illustrated with a case study from a real-world codebase. Because the techniques are language neutral, you can apply them to your own code no matter what programming language you use. Guide organizational decisions with objective data by measuring how well your development teams align with the software architecture. Apply research findings from social psychology to software development, ensuring you get the tools you need to coach your organization towards better code. If you're an experienced programmer, software architect, or technical manager, you'll get a new perspective that will change how you work with code. What You Need: You don't have to install anything to follow along in the book. TThe case studies in the book use well-known open source projects hosted on GitHub. You'll use CodeScene, a free software analysis tool for open source projects, for the case studies. We also discuss alternative tooling options where they exist.

Book SynopsisThe humanities and social sciences are interested in the cybersecurity object since its emergence in the security debates, at the beginning of the 2000s. This scientific production is thus still relatively young, but diversified, mobilizing at the same time political science, international relations, sociology , law, information science, security studies, surveillance studies, strategic studies, polemology. There is, however, no actual cybersecurity studies. After two decades of scientific production on this subject, we thought it essential to take stock of the research methods that could be mobilized, imagined and invented by the researchers. The research methodology on the subject "cybersecurity" has, paradoxically, been the subject of relatively few publications to date. This dimension is essential. It is the initial phase by which any researcher, seasoned or young doctoral student, must pass, to define his subject of study, delimit the contours, ask the research questions, and choose the methods of treatment. It is this methodological dimension that our book proposes to treat. The questions the authors were asked to answer were: how can cybersecurity be defined? What disciplines in the humanities and social sciences are studying, and how, cybersecurity? What is the place of pluralism or interdisciplinarity?

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.
