This book focuses on the design of secure and efficient signature and signcryption schemes for vehicular ad-hoc networks (VANETs). We use methods such as public key cryptography (PKI), identity-based cryptography (IDC), and certificateless cryptography (CLC) to design bilinear pairing and elliptic curve cryptography-based signature and signcryption schemes and prove their security in the random oracle model. The signature schemes ensure the authenticity of source and integrity of a safety message. While signcryption schemes ensure authentication and confidentiality of the safety message in a single logical step. To provide readers to study the schemes that securely and efficiently process a message and multiple messages in vehicle to vehicle and vehicle to infrastructure communications is the main benefit of this book. In addition, it can benefit researchers, engineers, and graduate students in the fields of security and privacy of VANETs, Internet of vehicles securty, wireless body area networks security, etc.

In this introductory textbook the author explains the key topics in cryptography. He takes a modern approach, where defining what is meant by "secure" is as important as creating something that achieves that goal, and security definitions are central to the discussion throughout. The author balances a largely non-rigorous style - many proofs are sketched only - with appropriate formality and depth. For example, he uses the terminology of groups and finite fields so that the reader can understand both the latest academic research and "real-world" documents such as application programming interface descriptions and cryptographic standards. The text employs colour to distinguish between public and private information, and all chapters include summaries and suggestions for further reading. This is a suitable textbook for advanced undergraduate and graduate students in computer science, mathematics and engineering, and for self-study by professionals in information security. While the appendix summarizes most of the basic algebra and notation required, it is assumed that the reader has a basic knowledge of discrete mathematics, probability, and elementary calculus.

Move beyond the checklist and fully protect yourself from third-party cybersecurity risk Over the last decade, there have been hundreds of big-name organizations in every sector that have experienced a public breach due to a vendor. While the media tends to focus on high-profile breaches like those that hit Target in 2013 and Equifax in 2017, 2020 has ushered in a huge wave of cybersecurity attacks, a near 800% increase in cyberattack activity as millions of workers shifted to working remotely in the wake of a global pandemic. The 2020 SolarWinds supply-chain attack illustrates that lasting impact of this dramatic increase in cyberattacks. Using a technique known as Advanced Persistent Threat (APT), a sophisticated hacker leveraged APT to steal information from multiple organizations from Microsoft to the Department of Homeland Security not by attacking targets directly, but by attacking a trusted partner or vendor. In addition to exposing third-party risk vulnerabilities for other hackers to exploit, the damage from this one attack alone will continue for years, and there are no signs that cyber breaches are slowing. Cybersecurity and Third-Party Risk delivers proven, active, and predictive risk reduction strategies and tactics designed to keep you and your organization safe. Cybersecurity and IT expert and author Gregory Rasner shows you how to transform third-party risk from an exercise in checklist completion to a proactive and effective process of risk mitigation. Understand the basics of third-party risk management Conduct due diligence on third parties connected to your network Keep your data and sensitive information current and reliable Incorporate third-party data requirements for offshoring, fourth-party hosting, and data security arrangements into your vendor contracts Learn valuable lessons from devasting breaches suffered by other companies like Home Depot, GM, and Equifax The time to talk cybersecurity with your data partners is now. Cybersecurity and Third-Party Risk is a must-read resource for business leaders and security professionals looking for a practical roadmap to avoiding the massive reputational and financial losses that come with third-party security breaches.

This book explores the genesis of ransomware and how the parallel emergence of encryption technologies has elevated ransomware to become the most prodigious cyber threat that enterprises are confronting. It also investigates the driving forces behind what has been dubbed the 'ransomware revolution' after a series of major attacks beginning in 2013, and how the advent of cryptocurrencies provided the catalyst for the development and increased profitability of ransomware, sparking a phenomenal rise in the number and complexity of ransomware attacks. This book analyzes why the speed of technology adoption has been a fundamental factor in the continued success of financially motivated cybercrime, and how the ease of public access to advanced encryption techniques has allowed malicious actors to continue to operate with increased anonymity across the internet. This anonymity has enabled increased collaboration between attackers, which has aided the development of new ransomware attacks, and led to an increasing level of technical complexity in ransomware attacks. This book highlights that the continuous expansion and early adoption of emerging technologies may be beyond the capacity of conventional risk managers and risk management frameworks. Researchers and advanced level students studying or working in computer science, business or criminology will find this book useful as a reference or secondary text. Professionals working in cybersecurity, cryptography, information technology, financial crime (and other related topics) will also welcome this book as a reference.

Cyber-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.

This book describes the efficient implementation of public-key cryptography (PKC) to address the security challenges of massive amounts of information generated by the vast network of connected devices, ranging from tiny Radio Frequency Identification (RFID) tags to powerful desktop computers. It investigates implementation aspects of post quantum PKC and homomorphic encryption schemes whose security is based on the hardness of the ring-learning with error (LWE) problem. The work includes designing an FPGA-based accelerator to speed up computation on encrypted data in the cloud computer. It also proposes a more practical scheme that uses a special module called recryption box to assist homomorphic function evaluation, roughly 20 times faster than the implementation without this module.

This book focuses on development of blockchain-based new-generation financial infrastructures, in which a systematic, complete theoretical framework is proposed to explore blockchain-based securities trading platform, central securities depository (CSD), securities settlement system (SSS), central counterparty (CCP), payment system (PS) and trade repository (TR). The blockchain-based new FMI has attracted much attention in the securities industry. At present, the cross-border depository receipt (DR) business faces a dilemma between efficiency and security. In this book, the author proposes a blockchain-based new DR solution, manifesting the potential for using blockchain technology in the FMI field. In addition, using Hashed Timelock Contract (HTLC) as the underlying technology in the DR scenario, specific process and operations are proposed for delivery versus payment (DvP), delivery versus delivery (DvD) or payment versus payment (PvP) and other exchange-of-value methods. This book further studies how to carry out opening positions, end-of-day settlement of margin, forced liquidation and settlement at maturity, for exchange-traded derivatives, such as futures and options, under the blockchain-based technological framework. Blockchain technology not only naturally fits into the decentralized or non-centralized characteristic of the OTC market but also can effectively address the pain points and difficulties of the OTC market. This book provides an in-depth analysis of existing specific issues in China's bond market, regional equity markets and asset management market, among other OTC markets, and proposes relevant blockchain-based solutions. Blockchain technology does not change the public policy objectives for FMI. The blockchain-based new FMIs are still subject to compliance, safety and efficiency requirements. This book provides a comprehensive assessment of the applicability of the Principles for Financial Market Infrastructures (PFMI) to them, in particular, analyzes their legal basis, off-chain governance and system security.

This book covers the relationship of recent technologies (such as Blockchain, IoT, and 5G) with the cloud computing as well as fog computing, and mobile edge computing. The relationship will not be limited to only architecture proposal, trends, and technical advancements. However, the book also explores the possibility of predictive analytics in cloud computing with respect to Blockchain, IoT, and 5G. The recent advancements in the internet-supported distributed computing i.e. cloud computing, has made it possible to process the bulk amount of data in a parallel and distributed. This has made it a lucrative technology to process the data generated from technologies such as Blockchain, IoT, and 5G. However, there are several issues a Cloud Service Provider (CSP) encounters, such as Blockchain security in cloud, IoT elasticity and scalability management in cloud, Service Level Agreement (SLA) compliances for 5G, Resource management, Load balancing, and Fault-tolerance. This edited book will discuss the aforementioned issues in connection with Blockchain, IoT, and 5G. Moreover, the book discusses how the cloud computing is not sufficient and one needs to use fog computing, and edge computing to efficiently process the data generated from IoT, and 5G. Moreover, the book shows how smart city, smart healthcare system, and smart communities are few of the most relevant IoT applications where fog computing plays a significant role. The book discusses the limitation of fog computing and the need for the edge computing to further reduce the network latency to process streaming data from IoT devices. The book also explores power of predictive analytics of Blockchain, IoT, and 5G data in cloud computing with its sister technologies. Since, the amount of resources increases day-by day, artificial intelligence (AI) tools are becoming more popular due to their capability which can be used in solving wide variety of issues, such as minimize the energy consumption of physical servers, optimize the service cost, improve the quality of experience, increase the service availability, efficiently handle the huge data flow, manages the large number of IoT devices, etc.
