"[Foundations of Cryptography: Basic Tools] presents complexity research which gives the mathematical underpinnings for cryptography; this includes one-way functions, pseudorandom generators, and zero-knowledge proofs...if a reader wants to learn about foundational work, Goldreich's books are the place to go."
Bulletin of the American Mathematical Society
"Foundations of Cryptography contains what is currently the best published treatment of the formal aspects of modern cryptography and serves as "required reading" for anyone interested in the field... Throughout, definitions are complete and detailed; proofs are rigorous and given in full... Th book remains a "must-read' for all graduate students and researchers interested in this area, and is well-suited for an advanced course. Kudos to the author for publishing the first book which truly covers modern cryptography, and for doing an excellent job of it!"

Cryptography is concerned with the conceptualization, definition and construction of computing systems that address security concerns. The design of cryptographic systems must be based on firm foundations. This book focuses on the basic mathematical tools needed for for cryptographic design: computational difficulty (one-way functions), pseudorandomness and zero-knowledge proofs. The emphasis is on the clarification of fundamental concepts, and on demonstrating the feasibility of solving several central cryptographic problems. The book is suitable for use in a graduate course on cryptography and as a reference book for experts. The author assumes basic familiarity with the design and analysis of algorithms; some knowledge of complexity theory and probability is also useful.
