'This book is provided with plenty of exercises and is excellent for an undergraduate course in Cryptography.' Zentralblatt MATH
'Cryptography plays a crucial role in many aspects of today's world ... Understanding the principles on which it is based is an important topic that requires a knowledge of both computational complexity and a range of topics in pure mathematics. This book provides that knowledge, combining an informal style with rigourous proofs of the key results to give an accessible introduction.' L'enseignement mathematique
'This is a nice introductory textbook that covers the most important areas of cryptography in an easily accessible manner, provides numerous examples and easy exercises, and I really enjoyed reading it.' ACM SIGACT News
'The book is beautifully structured and elegantly written in a compact yet accessible style. It is based on a course taught by the authors and has numerous problems, many provided with hints and or solutions. For these reasons, it is ideally suited for an advanced undergraduate or post graduate course.' The Times Higher Education Supplement
...useful to mathematicians wishing to learn more complexity theory...Very readable...a very well-written book. The Mathematical Association of America
The book is well organized and very clearly written, with an abundance of well-thought-out exercises. Mathematical Reviews
This is a nice introductory textbook that covers the most important areas of cryptography in an easily accessible manner, provides numerous examples and easy exercises, and I really enjoyed reading it.... a recommendable source for an introductory course on cryptography...

Their exposition is very clear, and they give a large number of examples throughout this discussion that made the book very readable even to those of us whose interests tend far more towards the theoretical than the algorithmic... A very well-written book that fills its niche quite well, and will make a welcome addition to any collection. Darren Glass, Gettysburg College for MAA Reviews
