With billions of computers in existence, cyberspace, 'the virtual world created when they are connected,' is said to be the new medium of power. Computer hackers operating from anywhere can enter cyberspace and take control of other people's computers, stealing their information, corrupting their workings, and shutting them down. Modern societies and militaries, both pervaded by computers, are supposedly at risk. As Conquest in Cyberspace explains, however, information systems and information itself are too easily conflated, and persistent mastery over the former is difficult to achieve. The author also investigates how far 'friendly conquest' in cyberspace extends, such as the power to persuade users to adopt new points of view. He discusses the role of public policy in managing cyberspace conquests and shows how the Internet is becoming more ubiquitous and complex, such as in the use of artificial intelligence.
'Cyber security' is a recent addition to the global security agenda, concerned with protecting states and citizens from the misuse of computer networks for war, terrorism, economic espionage and criminal gain. Many argue that the ubiquity of computer networks calls for robust and pervasive countermeasures, not least governments concerned at their potential effects on national and economic security. Drawing on critical literature in international relations, security studies, political theory and social theory, this is the first book that describes how these visions of future cyber security are sustained in the communities that articulate them. Specifically, it shows that conceptions of time and temporality are foundational to the politics of cyber security. It explores how cyber security communities understand the past, present and future, thereby shaping cyber security as a political practice. Integrating a wide range of conceptual and empirical resources, this innovative book provides insight for scholars, practitioners and policymakers.
The multidisciplinary field of quantum computing strives to exploit some of the uncanny aspects of quantum mechanics to expand our computational horizons. Quantum Computing for Computer Scientists takes readers on a tour of this fascinating area of cutting-edge research. Written in an accessible yet rigorous fashion, this book employs ideas and techniques familiar to every student of computer science. The reader is not expected to have any advanced mathematics or physics background. After presenting the necessary prerequisites, the material is organized to look at different aspects of quantum computing from the specific standpoint of computer science. There are chapters on computer architecture, algorithms, programming languages, theoretical computer science, cryptography, information theory, and hardware. The text has step-by-step examples, more than two hundred exercises with solutions, and programming drills that bring the ideas of quantum computing alive for today's computer science students and researchers.
