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 providing information security for everyday technologies such as the Internet, mobile phones, Wi-Fi networks, payment cards, Tor, and Bitcoin. This book is intended to be introductory, self-contained, and widely accessible. It is suitable as a first read on cryptography. Almost no prior knowledge of mathematics is required since the book deliberately avoids the details of the mathematics techniques underpinning cryptographic mechanisms. Instead our focus will be on what a normal user or practitioner of information security needs to know about cryptography in order to understand the design and use of everyday cryptographic applications. By focusing on the fundamental principles of modern cryptography rather than the technical details of current cryptographic technology, the main part this book is relatively timeless, and illustrates the application of these principles by considering a number of contemporary applications of cryptography. Following the revelations of former NSA contractor Edward Snowden, the book considers the wider societal impact of use of cryptography and strategies for addressing this. 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.
Does religious confession privilege exist at common law? Most evidence law texts answer ‘no’. This analysis shows that most of the cases relied upon for the ‘no religious confession privilege conclusion’ are not authority for that conclusion. The origin of the privilege in the canon law in the first millennium AD is traced and its reception into common law is documented. Proof that religious confession privilege continues unbroken at common law through to the present day is of obvious importance in jurisdictions where there is no relevant statute. A correct understanding of the common law extant before statutes were passed will influence whether those statutes are broadly or narrowly interpreted. The book also brings the reader up to date on the state of religious confession privilege in the United States, Canada, England, Wales, Scotland, Ireland, Australia, New Zealand and South Africa.
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.
