With ever more of our commercial and personal lives occurring electronically, network security is vital. When networks don’t have secure foundations, malware steals from us, invades our privacy, and threatens our safety. This guide uncovers the technology behind network security: its strengths, weaknesses, past, and future. It answers fundamental questions like: How do you identify yourself and prevent others from impersonating you? How do you communicate with others? How do you maintain your privacy? How do you buy and sell things? As a tutorial, it explains sophisticated concepts in a friendly and intuitive manner. As a reference, it covers concepts and techniques rigorously and in depth.
The authors cover a wide spectrum of topics essential for securing web-based transactions, including public and secret key cryptography, hashes/message digests, signatures, authentication, blockchains, electronic money, secret sharing, and multiparty computation. They also address exciting emerging issues such as quantum computing, post-quantum algorithms, homomorphic encryption, and secure multiparty computation.
Wherever math beyond high school algebra is needed, Network Security, 3rd Edition covers what students and other readers need to know, making it a self-contained solution suitable for undergraduate students, graduate students, and working engineers alike. To support learning and mastery, it also includes extensive homework problems, fully updated to reflect current concepts and technologies.
Charlie Kaufman is currently Security Architect for Dell Storage Systems. Previously, he was the Security Architect for Microsoft Azure and before that for Lotus Notes. He has contributed to a number of IETF standards efforts including IPsec, S/MIME, and DNSsec and served as a member of the Internet Architecture Board. He served on the National Academy of Sciences expert panel that wrote the book Trust In Cyberspace.
Radia Perlman is currently a Fellow at Dell Technologies. She is known for her contributions to bridging (spanning tree algorithm), routing (link state routing), and security (distributed systems robust despite malicious participants). She’s the author of Interconnections: Bridges, Routers, Switches, and Internetworking Protocols. She’s been elected to the National Academy of Engineering, the Inventors Hall of Fame, the Internet Hall of Fame, and awarded lifetime achievement awards from Usenix and ACM’s SIGCOMM. She has a PhD in computer science from MIT.
Ray Perlner is a Mathematician in the Cryptographic Technology Group of the National Institute of Standards and Technology. He has over a dozen research papers focusing primarily on postquantum cryptography. He has degrees in both physics and math from MIT.
