The Joy of Cryptography

A comprehensive introduction to the fundamentals of provable security for advanced undergraduates.
This accessible textbook provides a comprehensive introduction to the algorithms that keep our digital lives safe-how they work, what makes them different, and why they are secure. Mike Rosulek focuses on provable security-the process of defining what it means to be secure and mathematically proving security properties-to demystify the study of cryptography. Writing with clarity and humor, Rosulek covers basic building blocks before moving to symmetric-key encryption and authentication, public-key cryptography, and advanced topics. Employing a novel pseudocode-based approach to learning provable security and security proofs, The Joy of Cryptography empowers anyone with a small amount of programming experience to reason formally about security properties.
- Uses pseudocode-based reasoning to make provable security accessible to undergraduates- Focuses on proven methods used in practice today- Offers rigorous treatment of symmetric-key and public-key encryption and authentication- Includes advanced material on encrypted messaging, post-quantum cryptography, and zero-knowledge proofs- Features ancillary resources

Mike Rosulek is Professor in the School of Electrical Engineering and Computer Science at Oregon State University and author of over 60 peer-reviewed publications on cryptography, with a special focus on interactive protocols.
