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? How are the research topics chosen, the questions defined? How, concretely, to study cybersecurity: tools, methods, theories, organization of research, research fields, data ...? How are discipline-specific theories useful for understanding and studying cybersecurity? Has cybersecurity had an impact on scientific theories?Table of ContentsIntroduction ixDaniel VENTRE, Hugo LOISEAU and Hartmut ADEN Chapter 1 The “Science” of Cybersecurity in the Human and Social Sciences: Issues and Reflections 1Hugo LOISEAU 1.1 Introduction 1 1.2 A method? 4 1.3 Data? 11 1.4 One or more definition(s)? 16 1.5 Conclusion 20 1.6 References 21 Chapter 2 Definitions, Typologies, Taxonomies and Ontologies of Cybersecurity 25Daniel VENTRE 2.1 Introduction 25 2.2 Definition 27 2.2.1 What is a definition? 27 2.2.2 Usefulness of definitions 29 2.2.3 Rules for constructing definitions 29 2.2.4 Definitions of cybersecurity 32 2.3 Typology 43 2.3.1 What is a typology? 44 2.3.2 Usefulness of typologies 44 2.3.3 Rules for the construction of typologies 45 2.3.4 Cybersecurity typologies 46 2.4 Taxonomy 48 2.4.1 What is a taxonomy? 48 2.4.2 Usefulness of taxonomy 49 2.4.3 Rules for the construction of taxonomies 49 2.4.4 Taxonomies of cybersecurity 50 2.5 Ontologies 51 2.5.1 What is ontology? 52 2.5.2 Usefulness of ontologies 53 2.5.3 Rules for construction of ontologies 53 2.5.4 Cybersecurity ontologies 54 2.6 Conclusion 56 2.7 References 57 Chapter 3 Cybersecurity and Data Protection – Research Strategies and Limitations in a Legal and Public Policy Perspective 67Hartmut ADEN 3.1 Introduction 67 3.2 Studying the complex relationship between cybersecurity and data protection: endangering privacy by combating cybercrime? 68 3.2.1 Potential tensions between cybersecurity and data protection 69 3.2.2 Potential synergies between cybersecurity and data protection 72 3.3 Methodological approaches and challenges for the study of cybersecurity – legal and public policy perspectives 74 3.3.1 Legal interpretation and comparison as methodological approaches to the study of cybersecurity 74 3.3.2 Public policy approaches to the study of cybersecurity 77 3.3.3 Transdisciplinary synergies between legal and public policy perspectives 78 3.4 Conclusion and outlook 80 3.5 References 81 Chapter 4 Researching State-sponsored Cyber-espionage 85Joseph FITSANAKIS 4.1 Defining cybersecurity and cyber-espionage 85 4.2 Taxonomies of cyber-threats 87 4.3 The structure of this chapter 88 4.4 The significance of state-sponsored cyber-espionage 90 4.5 Research themes in state-sponsored cyber-espionage 94 4.6 Theorizing state-sponsored cyber-espionage in the social sciences 98 4.7 Research methodologies into state-sponsored cyber-espionage 104 4.8 Intellectual precision and objectivity in state-sponsored cyber-espionage research 106 4.9 Detecting state actors in cyber-espionage research 110 4.10 Identifying specific state actors in cyber-espionage research 112 4.11 Conclusion: researching a transformational subject 116 4.12 References 118 Chapter 5 Moving from Uncertainty to Risk: The Case of Cyber Risk 123Michel DACOROGNA and Marie KRATZ 5.1 Introduction 123 5.2 The scientific approach to move from uncertainty to risk 124 5.3 Learning about the data: the exploratory phase 126 5.4 Data cleansing 128 5.5 Statistical exploration on the various variables of the dataset 130 5.6 Univariate modeling for the relevant variables 134 5.7 Multivariate and dynamic modeling 139 5.7.1 A fast-changing environment: time dependency 140 5.7.2 Causal relations 143 5.7.3 Models for prediction 147 5.8 Conclusion 149 5.9 Acknowledgments 151 5.10 References 151 Chapter 6 Qualitative Document Analysis for Cybersecurity and Information Warfare Research 153Brett VAN NIEKERK and Trishana RAMLUCKAN 6.1 Introduction 153 6.1.1 Previous research 154 6.2 Information warfare and cybersecurity 154 6.3 Researching information warfare and cybersecurity 156 6.4 Qualitative research methodologies for information warfare and cybersecurity 157 6.4.1 Clustering of documents 159 6.4.2 Clustering of words 159 6.4.3 Word frequencies and word clouds 159 6.4.4 Text search and word trees 159 6.4.5 Example use cases of qualitative document analysis 160 6.5 An analysis of national cybersecurity strategies 161 6.5.1 Selection process for the documents 161 6.5.2 Analysis 162 6.5.3 Discussion 167 6.6 An analysis of the alignment of South Africa’s Cybercrimes Bill to international legislation 169 6.6.1 Background to the documents 169 6.6.2 Analysis 170 6.6.3 Discussion 174 6.7 An analysis of the influence of classical military philosophy on seminal information warfare texts 176 6.8 Reflections on qualitative document analysis for information warfare and cybersecurity research 177 6.9 Conclusion 179 6.10 References 180 Chapter 7 Anti-feminist Cyber-violence as a Risk Factor: Analysis of Cybersecurity Issues for Feminist Activists in France 185Elena WALDISPUEHL 7.1 Introduction 185 7.2 Localization of an online field 187 7.2.1 Online ethnographic work and empathy 192 7.2.2 Cybersecurity issues of an online field 193 7.3 Online–offline continuum 194 7.4 Continuum between security and insecurity 199 7.5 Conclusion 204 7.6 References 205 List of Authors 211 Index 213

Book SynopsisCyber-physical systems are the natural extension of the so-called “Internet of Things”. They are “systems of collaborating computational elements controlling physical entities”. Cyber Physical Systems of Systems (CPSoS) are considered “The Next Computing Revolution” after Mainframe computing (60’s-70’s), Desktop computing & Internet (80’s-90’s) and Ubiquitous computing (00’s); because all aspects of daily life are rapidly evolving towards humans interacting amongst themselves as well as their environment via computational devices (often mobile), and because in most cases systems will employ their computational capabilities to interact amongst themselves. CPSoS enable the physical world to merge with the cyber one. Using sensors, the embedded systems monitor and collect data from physical processes, such as the steering of a vehicle, energy consumption or human health functions. The systems are networked making the data globally available. CPSoS make it possible for software applications to directly interact with events in the physical world, for example to measure and react to changes in blood pressure or peaks in energy consumption. Embedded hardware and software systems crucially expand the functionality and competitiveness of vehicles, aircraft, medical equipment, production plants and household appliances. Connecting these systems to a virtual environment of globally networked services and information systems opens completely new areas of innovation and novel business platforms. Future CPSoS will have many sophisticated, interconnected parts that must instantaneously exchange, parse, and act on detailed data in a highly coordinated manner. Continued advances in science and engineering will be necessary to enable advances in design and development of these complex systems. Multi- scale, multi-layer, multi-domain, and multi-system integrated infrastructures will require new foundations in system science and engineering. Scientists and engineers with an understanding of otherwise physical systems will need to work in tandem with computer and information scientists to achieve effective, workable designs. In this tutorial, basic and advanced issues on the design of the future heterogeneous CPSoS are presented including relevant Blockchain technologies, reconfigurable systems, advanced sensor interfaces and human-centered design processes. Certain advanced tools for the design and implementation of the cyber parts of the CPSoS (i.e. FPGA design tools from Xilinx) are also covered.Table of Contents0. Introduction; 1. Meta-Arduino-ing Microcontroller-Based Cyber Physical System Design; 2. Adaptivity and self-awareness of CPSs and CPSoSs; 3. The use of Blockchain in supply chain management; 4.

Book SynopsisThis open access book covers the most cutting-edge and hot research topics and fields of post-quantum cryptography. The main purpose of this book is to focus on the computational complexity theory of lattice ciphers, especially the reduction principle of Ajtai, in order to fill the gap that post-quantum ciphers focus on the implementation of encryption and decryption algorithms, but the theoretical proof is insufficient. In Chapter 3, Chapter 4 and Chapter 6, author introduces the theory and technology of LWE distribution, LWE cipher and homomorphic encryption in detail. When using random analysis tools, there is a problem of "ambiguity" in both definition and algorithm. The greatest feature of this book is to use probability distribution to carry out rigorous mathematical definition and mathematical demonstration for various unclear or imprecise expressions, so as to make it a rigorous theoretical system for classroom teaching and dissemination. Chapters 5 and 7 further expand and improve the theory of cyclic lattice, ideal lattice and generalized NTRU cryptography.This book is used as a professional book for graduate students majoring in mathematics and cryptography, as well as a reference book for scientific and technological personnel engaged in cryptography research.Table of ContentsChapter 1. Gauss lattice theory.- Chapter 2. Reduction principle of Ajtai.- Chapter 3. Learning with errors.- Chapter 4. LWE cryptosystem.- Chapter 5. Cyclic lattice and Ideal lattice.- Chapter 6.

Book SynopsisThis book presents the benefits of the synergetic effect of the combination of coding and cryptography. It introduces new directions for the interoperability between the components of a communication system. Coding and cryptography are standard components in today’s distributed systems. The integration of cryptography into coding aspects is very interesting, as the usage of cryptography will be common use, even in industrial applications. The book is based on new developments of coding and cryptography, which use real numbers to express reliability values of bits instead of binary values 0 and 1. The presented methods are novel and designed for noisy communication, which doesn´t allow the successful use of cryptography. The rate of successful verifications is improved essentially not only for standard or “hard” verification, but even more after the introduction of “soft” verification. A security analysis shows the impact on the security. Information security and cryptography follow the late developments of communication theory by changing from “hard” to “soft”, which results in much better results.

Book SynopsisIn 1974, the British government admitted that its WWII secret intelligence organization had read Germany's ciphers on a massive scale. The intelligence from these decrypts influenced the Atlantic, the Eastern Front and Normandy. Why did the Germans never realize the Allies had so thoroughly penetrated their communications? As German intelligence experts conducted numerous internal investigations that all certified their ciphers' security, the Allies continued to break more ciphers and plugged their own communication leaks. How were the Allies able to so thoroughly exploit Germany's secret messages? How did they keep their tremendous success a secret? What flaws in Germany's organization allowed this counterintelligence failure and how can today's organizations learn to avoid similar disasters? This book, the first comparative study of WWII SIGINT (Signals Intelligence), analyzes the characteristics that allowed the Allies SIGINT success and that fostered the German blindness to Enigma'Trade Review'This book is a major addition to the existing literature on code breaking during the Second World War, and may well create a stir among historians of cryptology, especially in Europe.'
