Datakryptering

This book constitutes the refereed proceedings of the 8th International Conference on Security Standardisation Research, SSR 2023, held in Lyon, France, on April 22-23, 2023.The papers broadly cover cryptographic techniques, network security, identity management, security processes, standardization procedures, and more in the area of existing and newly developed security standards..

In May 1917, William and Elizebeth Friedman were asked by the U.S. Army to begin training officers in cryptanalysis and to decrypt intercepted German diplomatic and military communications. In June 1917, Herbert Yardley convinced the new head of the Army¿s Military Intelligence Division to create a code and cipher section for the Army with himself as its head. These two seminal events were the beginning of modern American cryptology, the growth of which culminated 35 years later with the creation of the National Security Agency. Each running their own cryptologic agencies in the 1920s, the Friedman-Yardley relationship was shattered after Yardley published a tell-all book about his time in military intelligence. Yet in the end, the work they all started in 1917 led directly to the modern American intelligence community. As they got older, they became increasingly irrelevant in the burgeoning American cryptologic fraternity. Topics and features:* Examines the lives of three remarkable and pioneering cryptologists* Offers fascinating insights into spies, codes and ciphers, rumrunners, poker, and military history* Sheds new light on interesting parts of the cryptologists¿ careers¿especially Elizebeth Friedman, whose work during World War II has just begun to be explored* Recounts several good stories, i.e., What if the Friedmans had gone to work for Herbert Yardley in his new Cipher Bureau in 1919? What if Yardley had moved back to Washington to work for William Friedman a decade later? This enjoyable book has wide appeal for: general readers interested in the evolution of American cryptology, American historians (particularly of World War I, the inter-war period, and World War II signals intelligence), and historians of¿and general readers interested in¿American military intelligence. It also can be used as an auxiliary text or recommended reading in introductory or survey courses in history or on the related topics.

This book contributes to blockchain applications in food supply chain management from both theoretical and practical perspectives. By using the case study research method, it empirically investigates why and how food companies implement blockchain technology. Moreover, it proposes a conceptual framework based on the case findings and extant literature.The book provides empirical evidence to verify academic findings such as critical success factors and barriers. Furthermore, it identifies the implementation process to answer the ¿how¿ question. Uniquely, it applies the innovation process model and the practice-based view (PBV) to studies on food supply chains and blockchain. Thus, building on the original model and theory, it enriches the theory on blockchain implementation, making it a valuable asset for all researchers and practitioners interested in blockchain adoption and food supply chain management.

Felix Müller-Eising untersucht die Nutzung der Blockchain-Technologie für das Grundbuch, das Handelsregister und das Aktienregister. Zuerst wird eine Einführung in die allgemeine Funktionsweise einer Blockchain gegeben, wobei Token, kryptografische Schlüssel, Smart Contracts und Konsensmechanismen wie Proof-of-Work und Proof-of-Stake erläutert werden. Danach werden dezentrale und zentrale Einsatzmöglichkeiten einer Blockchain für die Register untersucht. Er kommt zu dem Ergebnis, dass sowohl das Grundbuch als auch das Handelsregister durch eine Blockchain keinen deutlichen Mehrwert erhalten würden. Dagegen habe die Tokenisierung von Aktien in einem blockchainbasierten Aktienregister einige Vorteile, die den Einsatz einer Blockchain rechtfertigen würden.

With the rapid penetration of technology in varied application domains, the existing cities are getting connected more seamlessly. Cities becomes smart by inducing ICT in the classical city infrastructure for its management. According to McKenzie Report, about 68% of the world population will migrate towards urban settlements in near future. This migration is largely because of the improved Quality of Life (QoL) and livelihood in urban settlements. In the light of urbanization, climate change, democratic flaws, and rising urban welfare expenditures, smart cities have emerged as an important approach for society¿s future development. Smart cities have achieved enhanced QoL by giving smart information to people regarding healthcare, transportation, smart parking, smart traffic structure, smart home, smart agronomy, community security etc. Typically, in smart cities data is sensed by the sensor devices and provided to end users for further use. The sensitive data is transferredwith the help of internet creating higher chances for the adversaries to breach the data. Considering the privacy and security as the area of prime focus, this book covers the most prominent security vulnerabilities associated with varied application areas like healthcare, manufacturing, transportation, education and agriculture etc. Furthermore, the massive amount of data being generated through ubiquitous sensors placed across the smart cities needs to be handled in an effective, efficient, secured and privacy preserved manner. Since a typical smart city ecosystem is data driven, it is imperative to manage this data in an optimal manner. Enabling technologies like Internet of Things (IoT), Natural Language Processing (NLP), Blockchain Technology, Deep Learning, Machine Learning, Computer vision, Big Data Analytics, Next Generation Networks and Software Defined Networks (SDN) provide exemplary benefits if they are integrated in the classical city ecosystem in an effective manner. The application of Artificial Intelligence (AI) is expanding across many domains in the smart city, such as infrastructure, transportation, environmental protection, power and energy, privacy and security, governance, data management, healthcare, and more. AI has the potential to improve human health, prosperity, and happiness by reducing our reliance on manual labor and accelerating our progress in the sciences and technologies. NLP is an extensive domain of AI and is used in collaboration with machine learning and deep learning algorithms for clinical informatics and data processing. In modern smart cities, blockchain provides a complete framework that controls the city operations and ensures that they are managed as effectively as possible. Besides having an impact on our daily lives, it also facilitates many areas of city management.

This book focuses on conducting a comprehensive analysis of blockchain scalability serving large-scale application scenarios, from the ¿what, why, how¿ three perspectives, layer by layer. Gathering the latest state-of-the-art research advances in the area of key issues and technologies for blockchain scalability, it also presents some special and exciting insights on the existing and future blockchain scalability.Despite blockchain¿s merits of decentralization, immutability, non-repudiation, and traceability, the current blockchain has faced a serious scalability bottleneck. The scalability bottleneck problem is mainly manifested in two aspects: low-performance efficiency and difficulty in functional extension. First, the security and reliability of the blockchain system come from the fact that most nodes of the whole network participate in a distributed consensus to maintain the ledger. The high-cost consensus mechanism makes limited performance of blockchain, and there isa big gap between the actual large-scale application system. In addition, in order to ensure the security of a single blockchain system, data between different blockchain systems are relatively isolated, making it difficult for assets and data to interact.This book explores the scalability of blockchain in depth, proposes meaningful approaches to the problems mentioned above, and builds an original theoretical system of blockchain scalability. It describes the root of blockchain scalability problems, mainstream blockchain performance, the classification of existing scalability problem solutions, and some exciting sharding-based approaches. It also includes open issues and future directions to scale blockchain for complex practical application scenarios. As such, this book will be a valuable resource for students, researchers, engineers, and policymakers working in various areas related to blockchain scalability, which is also of great significance for understanding and solving the bottleneck of blockchain scalability and realizing the practical large-scale commercial application of blockchain.
