<p>The study of cryptography is motivated by and driven forward by security requirements. This volume presents the fundamental definitions, precise assumptions, and rigorous security proofs of cryptographic primitives and related protocols. It also describes how they originated from security requirements and how they are applied. Providing vivid demonstrations of how modern cryptographic techniques can be used to solve security problems, the book's applications cover wired and wireless communication networks, satellite communication networks, multicast/broadcast and TV networks, and newly emerging networks. It also describes some open problems that challenge the new directions of modern cryptography. </p>
