This book was released on 2023-11-16 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive review and reassessment of the classical sources describing the cryptographic Spartan device known as the scytale. Challenging the view promoted by modern historians of cryptography which look at the scytale as a simple and impractical 'stick', Diepenbroek argues for the scytale's deserved status as a vehicle for secret communication in the ancient world. By way of comparison, Diepenbroek demonstrates that the cryptographic principles employed in the Spartan scytale show an encryption and coding system that is no less complex than some 20th-century transposition ciphers. The result is that, contrary to the accepted point of view, scytale encryption is as complex and secure as other known ancient ciphers. Drawing on salient comparisons with a selection of modern transposition ciphers (and their historical predecessors), the reader is provided with a detailed overview and analysis of the surviving classical sources that similarly reveal the potential of the scytale as an actual cryptographic and steganographic tool in ancient Sparta in order to illustrate the relative sophistication of the Spartan scytale as a practical device for secret communication. This helps to establish the conceptual basis that the scytale would, in theory, have offered its ancient users a secure method for secret communication over long distances.

Book Synopsis Quantum Computing and the Financial System: Spooky Action at a Distance? by : International Monetary Fund
Download or read book Quantum Computing and the Financial System: Spooky Action at a Distance? written by International Monetary Fund and published by International Monetary Fund. This book was released on 2021-03-12 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: The era of quantum computing is about to begin, with profound implications for the global economy and the financial system. Rapid development of quantum computing brings both benefits and risks. Quantum computers can revolutionize industries and fields that require significant computing power, including modeling financial markets, designing new effective medicines and vaccines, and empowering artificial intelligence, as well as creating a new and secure way of communication (quantum Internet). But they would also crack many of the current encryption algorithms and threaten financial stability by compromising the security of mobile banking, e-commerce, fintech, digital currencies, and Internet information exchange. While the work on quantum-safe encryption is still in progress, financial institutions should take steps now to prepare for the cryptographic transition, by assessing future and retroactive risks from quantum computers, taking an inventory of their cryptographic algorithms (especially public keys), and building cryptographic agility to improve the overall cybersecurity resilience.

Book Synopsis Lawmaking and Adjudication in Archaic Greece by : Zinon Papakonstantinou
Download or read book Lawmaking and Adjudication in Archaic Greece written by Zinon Papakonstantinou and published by A&C Black. This book was released on 2014-06-20 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Lawmaking and Adjudication in Archaic Greece" re-evaluates central aspects of the genesis and application of laws in the communities of archaic Greece, including the structure and function of legislative bodies, the composition of the courts, the administration of justice and the use and abuse of legal norms and procedures by litigants in the courts and everyday settings. Combining a detailed analysis of epigraphical and literary evidence and the application of a model of interpretation borrowed from cultural analyses of law, this book argues that far from being monolithic creations of archaic polities that unilaterally informed social life, archaic legal systems can be more appropriately viewed as ideologically polyvalent and socially complex.It includes legal norms and the administration of justice articulated associations with divine and secular authority but also incorporated, mainly in their reception and application by average citizens, discourses of utility and resistance that actively contributed in the composition of social relations.
Book Synopsis A Methodology for the Cryptanalysis of Classical Ciphers with Search Metaheuristics by : George Lasry
Download or read book A Methodology for the Cryptanalysis of Classical Ciphers with Search Metaheuristics written by George Lasry and published by kassel university press GmbH. This book was released on 2018 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cryptography, the art and science of creating secret codes, and cryptanalysis, the art and science of breaking secret codes, underwent a similar and parallel course during history. Both fields evolved from manual encryption methods and manual codebreaking techniques, to cipher machines and codebreaking machines in the first half of the 20th century, and finally to computerbased encryption and cryptanalysis from the second half of the 20th century. However, despite the advent of modern computing technology, some of the more challenging classical cipher systems and machines have not yet been successfully cryptanalyzed. For others, cryptanalytic methods exist, but only for special and advantageous cases, such as when large amounts of ciphertext are available. Starting from the 1990s, local search metaheuristics such as hill climbing, genetic algorithms, and simulated annealing have been employed, and in some cases, successfully, for the cryptanalysis of several classical ciphers. In most cases, however, results were mixed, and the application of such methods rather limited in their scope and performance. In this work, a robust framework and methodology for the cryptanalysis of classical ciphers using local search metaheuristics, mainly hill climbing and simulated annealing, is described. In an extensive set of case studies conducted as part of this research, this new methodology has been validated and demonstrated as highly effective for the cryptanalysis of several challenging cipher systems and machines, which could not be effectively cryptanalyzed before, and with drastic improvements compared to previously published methods. This work also led to the decipherment of original encrypted messages from WWI, and to the solution, for the first time, of several public cryptographic challenges.
Book Synopsis Ancient Greek Cosmogony by : Andrew Gregory
Download or read book Ancient Greek Cosmogony written by Andrew Gregory and published by A&C Black. This book was released on 2008-01-03 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ancient Greek Cosmogony is the first detailed, comprehensive account of ancient Greek theories of the origins of the world. It covers the period from 800 BC to 600 AD, beginning with myths concerning the creation of the world; the cosmogonies of all the major Greek and Roman thinkers; and the debate between Greek philosophical cosmogony and early Christian views. It argues that Greeks formulated many of the perennial problems of philosophical cosmogony and produced philosophically and scientifically interesting answers. The atomists argued that our world was one among many worlds, and came about by chance. Plato argued that it is unique, and the product of design. Empedocles and the Stoics, in quite different ways, argued that there was an unending cycle whereby the world is generated, destroyed and generated again. Aristotle on the other hand argued that there was no such thing as cosmogony, and the world has always existed. Reactions to, and developments of, these ideas are traced through Hellenistic philosophy and the debates in early Christianity on whether God created the world from nothing or from some pre-existing chaos. The book examines issues of the origins of life and the elements for the ancient Greeks, and how the cosmos will come to an end. It argues that there were several interesting debates between Greek philosophers on the fundamental principles of cosmogony, and that these debates were influential on the development of Greek philosophy and science.

This book was released on 2004-12-28 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crime and punishment, criminal law and its administration, are areas of ancient history that have been explored less than many other aspects of ancient civilizations. Throughout history women have been affected by crime both as victims and as offenders. Yet, in the ancient world customary laws were created by men, formal laws were written by men, and both were interpreted and enforced by men.
Book Synopsis Revenge in Athenian Culture by : Fiona McHardy
Download or read book Revenge in Athenian Culture written by Fiona McHardy and published by A&C Black. This book was released on 2008-02-01 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Revenge was an all important part of the ancient Athenian mentality, intruding on all forms of life - even where we might not expect to find it today. Revenge was of prime importance as a means of survival for the people of early Greece and remained in force as a ‘cultural emotion’ during the rise of the poleis, even when the socio-political situation allowed people to live together more peaceably. A key reason for this was the concept of revenge as ‘justice’, which survived strongly in Athens even after the rise of the law-courts. Only the radical thoughts of Plato suggested that revenge was immoral and did not constitute justice. Nevertheless, this does not mean that all forms of revenge were seen as equally acceptable in Athens. Through a close examination of the texts, a more complex picture of how the Athenian people viewed revenge emerges.
Book Synopsis A Short History of Ancient Greece by : PJ Rhodes
Download or read book A Short History of Ancient Greece written by PJ Rhodes and published by Bloomsbury Publishing. This book was released on 2014-09-25 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical Greece and its legacy have long inspired a powerful and passionate fascination. The civilization that bequeathed to later ages drama and democracy, Homer and heroism, myth and Mycenae and the Delphic Oracle and the Olympic Games has, perhaps more than any other, helped shape the intellectual contours of the modern world. P J Rhodes is among the most distinguished historians of antiquity. In this elegant, zesty new survey he explores the archaic (8th–early 5th centuries BCE), classical (5th and 4th centuries BCE) and Hellenistic (late 4th–mid-2nd centuries BCE) periods up to the beginning of Roman hegemony. His scope is that of the peoples who originated on the Greek mainland and Aegean islands who later migrated to the shores of the Mediterranean and Black Seas, and then (following the conquests of Alexander) to the Near East and beyond. Exploring topics such as the epic struggle with Persia; the bitter rivalry of Athens and Sparta; slaves and ethnicity; religion and philosophy; and literature and the visual arts, this authoritative book will attract students and non-specialists in equal measure.

Download or read book Xenophon written by Fiona Hobden and published by Bloomsbury Publishing. This book was released on 2020-11-12 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a concise introduction to Xenophon, the Athenian historian, political thinker, moral philosopher and literary innovator who was also a pupil of Socrates, a military general on campaign in Persia, and an exile in residence in the Peloponnese during the late fifth and fourth centuries BC. Alive during one of the most turbulent periods in Greek history, Xenophon wrote extensively about the past and present. In doing so he not only invented several new genres, but also developed pointed political analyses and probing moral critiques. It is the purpose of this book to explore Xenophon's life, writing and ideas, and reception through thematic studies that draw upon the full range of his work. Starting with his approach to the past and to Socrates, it demonstrates how the depiction of events and people from previous times and places are inflected with contemporary concerns about political instability and the challenges of leadership, as well as by a 'Socratic' perspective on politics and morality. The following in-depth examination of Xenophon's theories concerning political organization and the bases for a good life highlight the interconnectivity of his ideas about how to live together and how to live well. Although Xenophon addresses conceptual issues, his writings provide a practical response to real-life problems. Finally, an evaluation of his significance as an inspiration to later writers in their creative interrogations of human affairs brings the investigations to a close. This book thus illuminates Xenophon's importance within the vibrant intellectual culture of ancient Greece as an active participant in and evaluator of his world, as well as his impact over time.
