Modern Cryptography: Theory and Practice (Hewlett-Packard Professional Books) (Hardcover)

Modern Cryptography is an indispensable resource for every advanced student of cryptography who intends to implement strong security in real-world applications. Leading HP security expert Wenbo Mao explains why conventional crypto schemes, protocols, and systems are profoundly vulnerable, introducing both fundamental theory and real-world attacks. Next, he shows how to implement crypto systems that are truly “fit for application,” and formally demonstrate their fitness. He begins by reviewing the foundations of cryptography: probability, information theory, computational complexity, number theory, algebraic techniques, and more. He presents the “ideal” principles of authentication, comparing them with real-world implementation. Mao assesses the strength of IPSec, IKE, SSH, SSL, TLS, Kerberos, and other standards, and offers practical guidance on designing stronger crypto schemes and using formal methods to prove their security and efficiency. Finally, he presents an in-depth introduction to zero-knowledge protocols: their characteristics, development, arguments, and proofs. Mao relies on practical examples throughout, and provides all the mathematical background students will need.

"This book would be a good addition to any cryptographer's bookshelf. The book is self-contained; it presents all the background material to understand an algorithm and all the development to prove its security. I'm not aware of another book that's as complete as this one."

--Christian Paquin, Cryptographic/Security Developer, Silanis Technology Inc. "The book is both complete, and extraordinarily technically accurate. It would certainly be a useful addition to any cryptographer's or crypto-engineer's library."

--Marcus Leech, Advisor, Security Architecture and Planning, Nortel Networks Build more secure crypto systems--and prove their trustworthiness Modern Cryptography is the indispensable resource for every technical professional who needs to implement strong security in real-world applications.

Leading HP security expert Wenbo Mao explains why "textbook" crypto schemes, protocols, and systems are profoundly vulnerable by revealing real-world-scenario attacks. Next, he shows how to realize cryptographic systems and protocols that are truly "fit for application"--and formally demonstrates their fitness. Mao presents practical examples throughout and provides all the mathematical background you'll need.

Coverage includes:

• Crypto foundations: probability, information theory, computational complexity, number theory, algebraic techniques, and more
• Authentication: basic techniques and principles vs. misconceptions and consequential attacks
• Evaluating real-world protocol standards including IPSec, IKE, SSH, TLS (SSL), and Kerberos
• Designing stronger counterparts to vulnerable "textbook" crypto schemes

Mao introduces formal and reductionist methodologies to prove the "fit-for-application" security of practical encryption, signature, signcryption, and authentication schemes. He gives detailed explanations for zero-knowledge protocols: definition, zero-knowledge properties, equatability vs. simulatability, argument vs. proof, round-efficiency, and non-interactive versions.
