  • Presents a comprehensive introduction to the role that cryptography plays in the modern world
  • Introductory, self-contained and widely accessible
  • Focuses on the issues that are of concern to users and practitioners, rather than theorists
  • Can be used as the basis of an educational course through the provision of structured learning outcomes, further reading and activities for each chapter
  • Also considers wider societal issues that arise concerning the use of cryptography
  • Almost no prior knowledge of mathematics is required

New to this Edition:

  • New chapter on controlling use of cryptography following revelations by former NSA contractor Edward Snowden
  • New chapter on cryptographic protection of personal devices such as mobile phones, including cryptography behind WhatsApp and Apple's iOS operating system
  • New case studies concerning Tor and Bitcoin
  • Updated case studies to feature new developments including TLS 1.3, LTE and Apple Pay
  • Extended core material to include techniques gaining popularity such as SHA3, authenticated encryption modes, key derivation functions, and key wrapping

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.

Keith Martin, Professor of Information Security, Royal Holloway, University of London
Prof. Keith Martin is a Professor of Information Security at Royal Holloway, University of London. He first studied cryptography at Royal Holloway in the late 1980s. After research positions at the University of Adelaide, Australia and the University of Leuven, Belgium, he rejoined Royal Holloway in 2000. He was Director of Royal Holloway's renowned Information Security Group between 2010 and 2015. As well as being an active member of the cryptographic research community, he has considerable experience in teaching cryptography to non-mathematical students, including to Royal Holloway's pioneering MSc Information Security, industrial courses, and young audiences.

"Review from previous edition Overall, this book is a good nontechnical introduction to cryptography. The author covers essential topics, presents the ideas clearly, and provides problems for further explorations and a good bibliography of other sources" - MAA Review

"It is a very leisurely reading, well-structured and very detailed. It does not assume any mathematical knowledge, making it suitable for being used as a manual for a course on introduction to cryptography" - Vicente Muñoz, the European Mathematical Society

"On a page per page basis it actually represents great value, and should achieve a long shelf life as both textbook and good reference source In terms of a score; for students a 9.5, practitioners 8.5 and general interest readers 8.5, giving an overall average of 9/10. Overall, an excellent book" - Mike Rees MBCS CITP, The British Computer Society

"Everyday Cryptography: Fundamental Principles and Applications is an excellent reference" - Jawa Eyes
