Cryptography is concerned with the conceptualization, definition and construction of computing systems that address security concerns. This book presents a rigorous and systematic treatment of the foundational issues: defining cryptographic tasks and solving new cryptographic problems using existing tools. It focuses on the basic mathematical tools: computational difficulty (one-way functions), pseudorandomness and zero-knowledge proofs. Rather than describing ad-hoc approaches, this book emphasizes the clarification of fundamental concepts and the demonstration of the feasibility of solving cryptographic problems. It is suitable for use in a graduate course on cryptography and as a reference book for experts....

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...
