Cryptography is vital to keeping information safe, in an era when the formula to do so becomes more and more challenging. Written by a team of world-renowned cryptography experts, this essential guide is the definitive introduction to all major areas of cryptography: message security, key negotiation, and key management. You'll learn how to think like a cryptographer. You'll discover techniques for building cryptography into products from the start and you'll examine the many technical changes in the field.

After a basic overview of cryptography and what it means today, this indispensable resource covers such topics as block ciphers, block modes, hash functions, encryption modes, message authentication codes, implementation issues, negotiation protocols, and more. Helpful examples and hands-on exercises enhance your understanding of the multi-faceted field of cryptography.

Cryptography Engineering gets you up to speed in the ever-evolving field of cryptography.

Knowing how a camera works does not make you a great photographer. Knowing what cryptographic designs are and how existing cryptographic protocols work does not give you proficiency in using cryptography. You must learn to think like a cryptographer.

That is what this book will teach you. Dive deeply into specific, concrete cryptographic protocols and learn why certain decisions were made. Recognize the challenges and how to overcome them. With this book, which is suitable for both classroom and self-study, you will learn to use cryptography effectively in real-world systems.

Understand what goes into designing cryptographic protocols

Develop an understanding of the interface between cryptography and the surrounding system, including people, economics, hardware, software, ethics, policy, and other aspects of the real world

Look beyond the security protocol to see weaknesses in the surrounding system

Thwart the adversary by understanding how adversaries think

Learn how to build cryptography into new products
