Cryptography is concerned with the construction of schemes thatshould maintain a desired functionality, even under maliciousattempts aimed at making them deviate from it.The design of cryptographic systems has to be based on firm foundations;whereas ad-hoc approaches and heuristics are a very dangerous way to go.This work is aimed at presenting firm foundations for cryptography.The foundations of cryptography are the paradigms, approachesand techniques used to conceptualize, define and provide solutionsto natural ``security concerns''.The emphasis of the work is on the clarification of fundamental conceptsand on demonstrating the feasibility of solving several centralcryptographic problems.The current book is the second volume of this work, and it focuseson the main applications of Cryptography:encryption schemes, signature schemes and secure protocols.The first volume focused on the main tools of Modern Cryptography:computational difficulty (one-way functions), pseudorandomness and zero-knowledge proofs.ISBN 0-521-83084-2 Published in US in May 2004.

Foundations of Cryptography surveys the main paradigms, approaches and techniques used to conceptualize, define and provide solutions to natural cryptographic problems. The author starts by presenting some of the central tools; that is, computational difficulty (in the form of one-way functions), pseudorandomness, and zero-knowledge proofs. Based on these tools, the emphasis is shifted to the treatment of basic applications such as encryption and signature schemes as well as the design of general secure cryptographic protocols. The author has created a unique overview that includes well over 100 references. The accent is on the clarification of fundamental concepts and on demonstrating the feasibility of solving several central cryptographic problems. Foundations of Cryptography is an invaluable resource for all students, researchers and practitioners interested in the foundations that underpin modern cryptography.
