Back Cover

We are surrounded by cryptography, from the ATM, where we withdraw cash, mobile phones, and the Internet, to workplace security systems that protect business secrets, and the civil and military codes that protect the skies above us.

In this fascinating introduction to how cryptography actually works, Fred Piper and Sean Murphy highlight its all-pervasive impact on modern society. Tracing the major historical developments in cryptography to many present-day examples, which readers can sample themselves, such as creating digital signatures, this Very Short Introduction demystifies the art of cryptography, highlighting the considerable social and political, as well as practical, importance of data protection and authentication in the modern world.

Acknowledgements

This book has evolved over a number of years with many people making valuable comments and suggestions. We thank them all. We are particularly grateful to Gerry Cole, Ross Patel, and Peter Wild for reading the final draft, and to Adrian Culley and Kalatzis Nikolas for saving us from embarrassment by correcting some of our exercises. Most of all we appreciate the contribution of Pauline Stoner who managed to convert apparent random scribble into a presentable format. Her patience was frequently tested and the book would not have been completed without her.
