Learn to build cryptographic protocols that work in the real world

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
