Network Security: Private Communication in a Public World (Hardcover)

The classic guide to cryptography and network security - now fully updated!

"Alice and Bob are back!"

Widely regarded as the most comprehensive yet comprehensible guide to network security and cryptography, the previous editions of Network Security received critical acclaim for lucid and witty explanations of the inner workings of cryptography and network security protocols. In this edition, the authors have significantly updated and revised the previous content, and added new topics that have become important.

This book explains sophisticated concepts in a friendly and intuitive manner. For protocol standards, it explains the various constraints and committee decisions that led to the current designs. For cryptographic algorithms, it explains the intuition behind the designs, as well as the types of attacks the algorithms are designed to avoid. It explains implementation techniques that can cause vulnerabilities even if the cryptography itself is sound. Homework problems deepen your understanding of concepts and technologies, and an updated glossary demystifies the field's jargon. Network Security, Third Edition will appeal to a wide range of professionals, from those who design and evaluate security systems to system administrators and programmers who want a better understanding of this important field. It can also be used as a textbook at the graduate or advanced undergraduate level.

Coverage includes

• Network security protocol and cryptography basics
• Design considerations and techniques for secret key and hash algorithms (AES, DES, SHA-1, SHA-2, SHA-3)
• First-generation public key algorithms (RSA, Diffie-Hellman, ECC)
• How quantum computers work, and why they threaten the first-generation public key algorithms
• Multi-factor authentication of people
• Real-time communication (SSL/TLS, SSH, IPsec)
• New applications (electronic money, blockchains)
• New cryptographic techniques (homomorphic encryption, secure multiparty computation)

經典的密碼學和網路安全指南 - 現已全面更新！

「愛麗絲和鮑伯回來了！」

被廣泛認為是最全面且易於理解的網路安全和密碼學指南，先前版本的《網路安全》因對密碼學和網路安全協議內部運作的清晰且詼諧解釋而受到好評。在這個版本中，作者們大幅更新和修訂了先前的內容，並新增了一些重要的主題。

本書以友善且直觀的方式解釋複雜的概念。對於協議標準，它解釋了導致目前設計的各種限制和委員會決策。對於密碼算法，它解釋了設計背後的直覺，以及算法旨在避免的攻擊類型。它解釋了即使密碼學本身是安全的，實現技術也可能造成漏洞。作業問題加深了對概念和技術的理解，更新的詞彙表揭開了這個領域的術語。《網路安全》第三版將吸引各種專業人士，從設計和評估安全系統的人員到希望更好地了解這一重要領域的系統管理員和程式設計師。它也可以作為研究生或高級本科水平的教科書使用。

內容包括：

- 網路安全協議和密碼學基礎
- 秘密金鑰和雜湊算法的設計考慮和技術（AES、DES、SHA-1、SHA-2、SHA-3）
- 第一代公鑰算法（RSA、Diffie-Hellman、ECC）
- 量子計算機的運作方式，以及為何威脅第一代公鑰算法
- 人的多因素認證
- 即時通訊（SSL/TLS、SSH、IPsec）
- 新應用（電子貨幣、區塊鏈）
- 新的密碼學技術（同態加密、安全多方計算）
