This book was released on 2023-11-16 with total page 222 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 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.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Through its coverage of 19 epidemics associated with a broad range of wars, and blending medical knowledge, demographics, geographic, and medical information with historical and military insights, this book reveals the complex relationship between epidemics and wars throughout history. How did small pox have a tremendous effect on two distinct periods of war—one in which the disease devastated entire native armies and leadership, and the other in which technological advancements and the application of medical knowledge concerning the disease preserved an army and as a result changed the course of events? Epidemics and War: The Impact of Disease on Major Conflicts in History examines fascinating historical questions like this and dozens more, exploring a plethora of communicable diseases—viral, fungal, and/or bacterial in nature—that spread and impacted wars or were spread by some aspect of mass human conflict. Written by historians, medical doctors, and people with military backgrounds, the book presents a variety of viewpoints and research approaches. Each chapter examines an epidemic in relation to a period of war, demonstrating how the two impacted each other and affected the populations involved directly and indirectly. Starting with three still unknown/unidentified epidemics (ranging from Classical Athens to the Battle of Bosworth in England), the book's chapters explore a plethora of diseases that spread through wars or significantly impacted wars. The book also examines how long-ended wars can play a role in the spread of epidemics a generation later, as seen in the 21st-century mumps epidemic in Bosnia, 15 to 20 years after the Bosnian conflicts of the 1990s.

Book excerpt: Shell shock achieved a very high political profile in the years 1919-1922. Publications ranging from John Bull to the Morning Post insisted that shell-shocked men should be treated with respect, and the Minister for Health announced that the government was committed to protecting shell-shocked men from the stigma of lunacy. Yet at the same time, many mentally-wounded veterans were struggling with a pension system which was failing to give them security. It is this conflict between the political rhetoric and the lived experience of many wounded veterans that explains why the government was unable to dispel the negative wartime assessment of official shell-shock treatment. There was also a real conflict between the government's wish to forget shell shock whilst memorialising the war and remembering the war dead. As a result of these contradictions, shell shock was not forgotten, on the contrary, the shell-shocked soldier quickly grew to symbolise the confusions and inconsistencies of the Great War.

Biographical and organizational profiles combined with succinct overviews of each country provide a strong research foundation for students. The book offers detailed descriptions of the minority groups that have suffered violence from both the countries and the societies around them, sometimes generating refugee flows that engage neighboring states in security issues. It also discusses the role of women in the region during these turbulent times. Primary source documents and a chronology highlight political struggles to reach durable agreements and develop institutions to meet basic human needs in the modern Middle East.

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 during the rise of the 'poleis'. The revenge of epic heroes such as Odysseus and Menalaus influences later thinking about revenge and suggests that avengers prosper. Nevertheless, this does not mean that all forms of revenge were seen as equally acceptable in Athens. Differences in response are expected depending on the crime and the criminal. Through a close examination of the texts, Fiona McHardy here reveals a more complex picture of how the Athenian people viewed revenge.
