Network Security

Network Security: Private Communication in a Public World, 3rd Edition, is a textbook that examines foundational cryptography and network security protocols. The volume explores the principles, design rationales, and mechanisms that protect communications across networks.

The text covers secret key and public key algorithms alongside real-time communication protocols such as SSL/TLS and IPsec. It also investigates how quantum computers threaten traditional public key systems and introduces quantum-safe alternatives.

Suitable for advanced undergraduate and graduate study, the book also serves programmers, system administrators, and professionals who evaluate security systems. Learning is supported through homework problems and an updated glossary.
