Foundations of Cryptography

Cryptography: Foundations and Applications is a resource for students, professionals, and academics in the field of cryptography. It presents a rigorous and systematic treatment of foundational issues: defining cryptographic tasks and solving new cryptographic problems using existing tools. This book focuses on the basic mathematical tools: computational difficulty (one-way functions), pseudorandomness, and zero-knowledge proofs. Rather than describing ad-hoc approaches, the authors emphasize the clarification of fundamental concepts and the demonstration of the feasibility of solving cryptographic problems.
