    A broad introduction to cryptography—what it is, how it really works, what its future holds, and why every informed citizen should understand its basics.We all keep secrets—from our gym locker codes to our email passwords to our online interactions. And we choose to share those secrets only with those whom we trust. So, too, do organizations, businesses, governments, and armies. In this fascinating book Cryptography, Panos Louridas provides a broad and accessible introduction to cryptography, the art and science of keeping and revealing secrets. Louridas explains just how cryptography works to keep our communications confidential, tracing it back all the way to its ancient roots. Then he follows its long and winding path to where we are today and reads the signs that point to where it may go tomorrow.A few years back, interest in cryptography was restricted to specialists. Today, as we all live our lives attuned to our digital footprint and the privacy issues it entails, it becomes more and more essential to have a basic understanding of cryptography and its applications to everyday life. Starting with classical cryptography, Cryptography takes the reader all the way up to the twenty-first century cryptographic applications that underpin our lives in the digital realm. Along the way, Louridas also explains concepts such as symmetric cryptography, asymmetric cryptography, cryptographic protocols and applications, and finally, quantum and post-Quantum cryptography as well as the links between cryptography and computer security.

    This book takes readers through the sensational history of blockchains and their potential to revolutionize database systems of the future. In order to demystify blockchains, the book capitalizes on decades of research and field testing of existing database and distributed systems and applies these familiar concepts to the novel blockchain system. It then utilizes this framework to explore the essential block platform underpinning blockchains, which is often misunderstood as a specific attribute of cryptocurrencies rather than the core of the decentralized system independent of application. The book explores the nature of these decentralized systems, which have no single owner and build robustness through a multitude of stakeholder contributions. In this way, blockchains can build trust into existing systems and thus present attractive solutions for various domains across both academia and industry. Despite this, high-impact and real-world applications of blockchain have yet to be realized outside of cryptocurrencies like Bitcoin. The book establishes how this new data system, if properly applied, can disrupt the sector in much the same way databases did so many years ago. The book explores the fundamental technical limitations that may be preventing blockchain from realizing this potential and how to overcome or mitigate them. Readers who are completely new to blockchains will find this book to be a comprehensive survey of the state of the art in blockchain technology. Readers with some experience of blockchains, for example through developing cryptocurrencies, will likely find the book's database perspective enlightening. Finally, researchers already working with blockchain will learn to identify existing gaps in the design space and explore potential solutions for creating the next generation of blockchain systems.

    This wide-ranging book introduces information as a key concept not only in physics, from quantum mechanics to thermodynamics, but also in the neighboring sciences and in the humanities. The central part analyzes dynamical processes as manifestations of information flows between microscopic and macroscopic scales and between systems and their environment. Quantum mechanics is interpreted as a reconstruction of mechanics based on fundamental limitations of information processing on the smallest scales. These become particularly manifest in quantum chaos and in quantum computing. Covering subjects such as causality, prediction, undecidability, chaos, and quantum randomness, the book also provides an information-theoretical view of predictability. More than 180 illustrations visualize the concepts and arguments. The book takes inspiration from the author's graduate-level topical lecture but is also well suited for undergraduate studies and is a valuable resource for researchers and professionals.

    Fifty years after the first experiments in computational art, international interest in the history of this subject remains strong and at the same time almost uncovered. This book began with the exhibition Algorithmic Signs, which was conceived, researched and curated by Francesca Franco in Venice in 2017. The origins of the exhibition included a series of meetings that gathered together the most celebrated international pioneers in the world of digital arts and the rare opportunity to interview them in their studios.Francesca Franco explores the history of computer art and its contribution to the broader field of contemporary art from the 1960s to the present. It is illustrated by the creative work of five of the most influential pioneers of computer art - Ernest Edmonds, Manfred Mohr, Vera Molnár, Frieder Nake, and Roman Verostko and includes the full visual documentation of the exhibition.The Algorithmic Dimension - Five Artists in Conversation offersmore than a theoretical perspective; it offers readers the rare opportunity to hear the histories and developments of the fascinating art, created through the algorithm, in an accessible and stimulating narrative. The personal achievements of each artist are followed, including their original inspirations, and how they develop in parallel with technological advances. It also brings together for the first time the artists' common ideas and differences, and tales about how their paths have crossed over the years.

    This book studies the intersection between cryptography and AI, highlighting the significant cross-impact and potential between the two technologies. The authors first study the individual ecosystems of cryptography and AI to show the omnipresence of each technology in the ecosystem of the other one. Next, they show how these technologies have come together in collaborative or adversarial ways. In the next section, the authors highlight the coevolution being formed between cryptography and AI. Throughout the book, the authors use evidence from state-of-the-art research to look ahead at the future of the crypto-AI dichotomy. The authors explain how they anticipate that quantum computing will join the dichotomy in near future, augmenting it to a trichotomy. They verify this through two case studies highlighting another scenario wherein crypto, AI and quantum converge. The authors study current trends in chaotic image encryption as well as information-theoretic cryptography and show how these trends lean towards quantum-inspired artificial intelligence (QiAI). After concluding the discussions, the authors suggest future research for interested researchers.

    Die Kryptographie, wie sie in diesem Jahrhundert betrieben wird, ist stark mathematisch geprägt. Aber sie hat auch ihre Wurzeln in dem, was rechnerisch machbar ist.In diesem einzigartigen Lehrbuch werden die Theoreme der Mathematik gegen die Machbarkeit von Berechnungen abgewogen. Kryptografie ist etwas, das man tatsächlich "macht", kein mathematisches Spiel, über das man Theoreme beweist. Es gibt tiefgründige Mathematik; es gibt einige Theoreme, die bewiesen werden müssen; und es besteht die Notwendigkeit, die brillante Arbeit derjenigen anzuerkennen, die sich auf die Theorie konzentrieren. Auf der Ebene eines Grundstudiums sollte der Schwerpunkt jedoch zunächst darauf liegen, die Algorithmen zu kennen und zu verstehen und zu wissen, wie sie zu implementieren sind, und sich auch bewusst zu machen, dass die Algorithmen sorgfältig implementiert werden müssen, um die "einfachen" Wege zum Brechen der Kryptografie zu vermeiden. Dieser Text deckt die algorithmischen Grundlagen ab und wird durch Kernmathematik und Arithmetik ergänzt.
