Foundations of Cryptography by Oded Goldreich

Oded Goldreich’s Foundations of Cryptography is a two-volume masterpiece widely regarded as one of the most rigorous and authoritative texts on modern cryptography. Rather than presenting cryptography as a collection of tricks, the book establishes it as a mathematical discipline grounded in formal definitions, proofs, and security models. It is not a “how-to” manual but a conceptual framework that defines what cryptography can achieve, what assumptions are necessary, and how secure systems can be designed with provable guarantees.
