Foundations of Cryptography: Volume 1, Basic Tools at Dominant Systems Book Store

"[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 proofsif a reader wants to learn about foundational work, Goldreich's books are the place to go."
Bulletin of the American Mathematical Society

"well-written"
Zentralblatt MATH

"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!"

We all know what it means for an algorithm to compute a function, but what does it mean for an encryption scheme to be secure? Traditionally, cryptographic schemes were suggested and attacked based on ad-hoc criterias, for lack of a proper theoretical setting. The last two decades have seen enormous progress in this respect. New notions were devised to harness the computational difficulty of problems in a constructive way to achieve security (in various senses) against all adversaries. This enabled the definition of a host of well-defined cryptographic "objects" and investigation of their existence and relations. The planned 3-volume series aims to provide a thorough presentation of the theory, written by a dominant figure in the field. This first volume introduces the basic notions: one-way functions, pseudorandom generators, various zero-knowledge proof systems and related concepts. Curiously, common cryptographic objects such as encryption schemes and signature schemes are only briefly discussed in an appendix -- the author has chosen to postpone these to the Volume 2 in the interest of in-depth discussion of the simpler objects. Hence this volume does not stand well on its own, and until Volume 2 is published the impatient reader may be disappointed. Fortunately, drafts of Volume 2 are available on-line: www.wisdom.weizmann.ac.il/~oded/foc-vol2.html The presentation style is a tour de force of didactic sensitivity. The subject material is often problematic, because the mental gymnastics required are not quite like any other field. The author is fully aware of this, and provides ample intuitive discussion and motivation to help the reader through the more technical parts (without compromising rigorousness). A clear effort is made to present, or at least mention and reference, all interesting results pertaining to the discussion. This makes the book invaluable as a reference, though it could have been overwhelming had not the author taken care to separate these excursions from the main discussion. The exercises are usually well-considered and rewarding, and unlike some textbooks you won't find important results disguised as an optional exercise. Those interested primarily in practical applications of cryptography may well find this book too abstract and irrelevant; the relation between this book and Schneier's "Applied Cryptography" is roughly like that between organic chemistry and cooking. However, for those taking academic interest in the field or trying to devise novel cryptographic schemes, this book is an effective way to get a solid grasp on the theory, and a delightful way to understand this exciting branch of computer science.
