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.
