A “must-read” (Vincent Rijmen) nuts-and-bolts explanation of cryptography from a leading expert in information security. Despite its reputation as a language only of spies and hackers, cryptography plays a critical role in our everyday lives. Though often invisible, it underpins the security of our mobile phone calls, credit card payments, web searches, internet messaging, and cryptocurrencies—in short, everything we do online. Increasingly, it also runs in the background of our smart refrigerators, thermostats, electronic car keys, and even the cars themselves. As our daily devices get smarter, cyberspace—home to all the networks that connect them—grows. Broadly defined as a set of tools for establishing security in this expanding cyberspace, cryptography enables us to protect and share our information. Understanding the basics of cryptography is the key to recognizing the significance of the security technologies we encounter every day, which will then help us respond to them. What are the implications of connecting to an unprotected Wi-Fi network? Is it really so important to have different passwords for different accounts? Is it safe to submit sensitive personal information to a given app, or to convert money to bitcoin? In clear, concise writing, information security expert Keith Martin answers all these questions and more, revealing the many crucial ways we all depend on cryptographic technology. He demystifies its controversial applications and the nuances behind alarming headlines about data breaches at banks, credit bureaus, and online retailers. We learn, for example, how encryption can hamper criminal investigations and obstruct national security efforts, and how increasingly frequent ransomware attacks put personal information at risk. Yet we also learn why responding to these threats by restricting the use of cryptography can itself be problematic. Essential reading for anyone with a password, Cryptography offers a profound perspective on personal security, online and off.

Cryptography is a vital technology that underpins the security of information in computer networks. This book presents a comprehensive introduction to the role that cryptography plays in supporting digital security for everyday technologies such as the internet, mobile phones, Wi-Fi networks, payment cards and cryptocurrencies. This book is intended to be introductory, self-contained and widely accessible. It is suitable for a first read on cryptography. Almost no prior knowledge of mathematics is required since the book deliberately avoids the details of the mathematical techniques underpinning cryptographic mechanisms. Instead, it concerns what a normal user or practitioner of cyber security needs to know about cryptography in order to understand the design and use of everyday cryptographic applications. This includes the implementation of cryptography and key management. By focusing on the fundamental principles of modern cryptography rather than the technical details of the latest technology, the main part of the book is relatively timeless. The application of these principles illustrated by considering a number of contemporary uses of cryptography. These include emerging themes, such as post-quantum cryptography and the increased demand for cryptographic tools supporting privacy. The book also considers the wider societal impact of use of cryptography, including ransomware and the challenge of balancing the conflicting needs of society and national security when using cryptography. A reader of this book will not only be able to understand the everyday use of cryptography, but also be able to interpret future developments in this fascinating and crucially important area of technology.

Cryptography is a part of everyday life for almost all of us, though we may not realise we're using it. We are a far cry from the historical prediction that cryptography would only be used by militaries and governments. With vast quantities of sensitive information transferred online by individuals, companies, organizations, and nation states, cryptography is increasingly important to everyone, and most of us, often without realising, use it daily. Cryptography: A Very Short Introduction demystifies the art of cryptography by tracing its historical use, explaining how it works, and providing examples of its practical use. These include online shopping, chip and PIN bank cards, and communicating via mobile phone. While many of these uses have been mainstream for some time now, the development and deployment of cryptography has changed enormously in the last twenty years. In this second edition, Sean Murphy and Rachel Player highlight the important advances in both academic cryptography research and its everyday use. Using non-technical language and without assuming advanced mathematical knowledge, they introduce symmetric and public-key cryptography and provide a detailed discussion of the design of cryptographic algorithms that are secure against quantum computers and the development of cryptographic algorithms with advanced functionalities. They also consider the new applications of cryptography such as blockchain, secure messaging apps, and electronic voting. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Cryptography’s essential role in the functioning of the city, viewed against the backdrop of modern digital life. Cryptography is not new to the city; in fact, it is essential to its functioning. For as long as cities have existed, communications have circulated, often in full sight, but with their messages hidden. In Cryptographic City, Richard Coyne explains how cryptography runs deep within the structure of the city. He shows the extent to which cities are built on secrets, their foundations now reinforced by digital encryption and cryptocurrency platforms. He also uses cryptography as a lens through which to inspect smart cities and what they deliver. Coyne sets his investigation into the cryptographic city against the backdrop of the technologies, claims, and challenges of the smart city. Cryptography provides the means by which communications within and between citizens and devices are kept secure. Coyne shows how all of the smart city innovations—from smart toasters to public transportation networks—are enabled by secure financial transactions, data flows, media streaming, and communications made possible by encryption. Without encryption, he says, communications between people and digital devices would be exposed for anyone to see, hack, and misdirect. He explains the relevant technicalities of cryptography and describes the practical difference it makes to frame cities as cryptographic. Interwoven throughout the book are autobiographical anecdotes, insights from Coyne’s teaching practice, and historical reports, making it accessible to the general reader.
