"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 which see the scytale as a simple 'stick'. Diepenbroek argues for its 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"--

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.

As the metaverse rapidly evolves into a virtual realm where digital interactions mirror and sometimes surpass physical reality, ensuring robust security paradigms becomes critical. The complex and interconnected nature of the metaverse begs better exploration into user privacy, cyber threat prevention, and virtual asset integrity. Establishing reliable security frameworks in the metaverse involves identity management, data protection, decentralized governance models, and the mitigation of virtual and augmented reality vulnerabilities. By developing and implementing robust security paradigms, those who use the metaverse can foster trust, promote innovation, and facilitate the safe and sustainable growth of the metaverse ecosystem. Metaverse Security Paradigms addresses the multifaceted security challenges within the metaverse and virtual worlds, while exploring privacy techniques and ethical implications. It delves into the technological, legal, and ethical dimensions of security in virtual environments. This book covers topics such as privacy systems, risk management, and artificial intelligence, and is a useful resource for IT professionals, business owners, computer engineers, security workers, researchers, scientists, and academicians.

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.

Cryptology: Classical and Modern, Second Edition proficiently introduces readers to the fascinating field of cryptology. The book covers classical methods including substitution, transposition, Playfair, ADFGVX, Alberti, Vigene re, and Hill ciphers. It also includes coverage of the Enigma machine, Turing bombe, and Navajo code. Additionally, the book presents modern methods like RSA, ElGamal, and stream ciphers, as well as the Diffie-Hellman key exchange and Advanced Encryption Standard. When possible, the book details methods for breaking both classical and modern methods. The new edition expands upon the material from the first edition which was oriented for students in non-technical fields. At the same time, the second edition supplements this material with new content that serves students in more technical fields as well. Thus, the second edition can be fully utilized by both technical and non-technical students at all levels of study. The authors include a wealth of material for a one-semester cryptology course, and research exercises that can be used for supplemental projects. Hints and answers to selected exercises are found at the end of the book.

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.

"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.

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.
