Product Description

In this age of viruses and hackers, of electronic eavesdropping and electronic fraud, security is paramount. This solid, up-to-date tutorial is a comprehensive treatment of cryptography and network security is ideal for self-study. Explores the basic issues to be addressed by a network security capability through a tutorial and survey of cryptography and network security technology. Examines the practice of network security via practical applications that have been implemented and are in use today. Provides a simplified AES (Advanced Encryption Standard) that enables readers to grasp the essentials of AES more easily. Features block cipher modes of operation, including the CMAC mode for authentication and the CCM mode for authenticated encryption. Includes an expanded, updated treatment of intruders and malicious software. A useful reference for system engineers, programmers, system managers, network managers, product marketing personnel, and system support specialists.

Objectives

It is the purpose of this book to provide a practical survey of both the principles and practice of cryptography and network security. In the first two parts of the book, the basic issues to be addressed by a network security capability are explored by providing a tutorial and survey of cryptography and network security technology. The latter part of the book deals with the practice of network security: practical applications that have been implemented and are in use to provide network security.

The subject, and therefore this book, draws on a variety of disciplines. In particular, it is impossible to appreciate the significance of some of the techniques discussed in this book without a basic understanding of number theory and some results from probability theory. Nevertheless, an attempt has been made to make the book self-contained. The book presents not only the basic mathematical results that are needed but provides the reader with an intuitive understanding of those results. Such background material is introduced as needed. This approach helps to motivate the material that is introduced, and the author considers this preferable to simply presenting all of the mathematical material in a lump at the beginning of the book.

Intended Audience

The book is intended for both an academic and a professional audience. As a textbook, it is intended as a one-semester undergraduate course in cryptography and network security for computer science, computer engineering, and electrical engineering majors. It covers the material in IAS2 Security Mechanisms, a core area in the Information Technology body of knowledge; NET4 Security, another core area in the Information Technology body of knowledge; and IT311, Cryptography, an advanced course; these subject areas are part of the Draft ACM/IEEE Computer Society Computing Curricula 2005.

Plan of the Book
The book is organized in four parts:

Part One. Conventional Encryption: A detailed examination of conventional encryption algorithms and design principles, including a discussion of the use of conventional encryption for confidentiality.

Part Two. Public-Key Encryption and Hash Functions: A detailed examination of public-key encryption algorithms and design principles. This part also examines the use of message authentication codes and hash functions, as well as digital signatures and public-key certificates.

Part Three. Network Security Practice: Covers important network security tools and applications, including Kerberos, X.509v3 certificates, PGP, S/MIME, IP Security, SSL/TLS, and SET.

Part Four. System Security: Looks at system-level security issues, including the threat of and countermeasures for intruders and viruses, and the use of firewalls and trusted systems.

In addition, the book includes an extensive glossary, a list of frequently used acronyms, and a bibliography. Each chapter includes homework problems, review questions, a list of key words, suggestions for further reading, and recommended Web sites.

A more detailed, chapter-by-chapter summary of each part appears at the beginning of that part.

What's New in the Fourth Edition
In the three years since the third edition of this book was published, the field has seen continued innovations and improvements. In this new edition, I try to capture these changes while maintaining a broad and comprehensive coverage of the entire field. To begin this process of revision, the third edition was extensively reviewed by a number of professors who teach the subject. In addition, a number of professionals working in the field reviewed individual chapters. The result is that, in many places, the narrative has been clarified and tightened, and illustrations have been improved. Also, a large number of new "field-tested" problems have been added.

Beyond these refinements to improve pedagogy and user friendliness, there have been major substantive changes throughout the book. Highlights include the following:

Simplified AES: This is an educational, simplified version of AES (Advanced Encryption Standard), which enables students to grasp the essentials of AES more easily.

Whirlpool: This is an important new secure hash algorithm based on the use of a symmetric block cipher.

CMAC: This is a new block cipher mode of operation. CMAC (cipher-based message authentication code) provides message authentication based on the use of a symmetric block cipher.

Public-key infrastructure (PKI): This important topic is treated in this new edition.

Distributed denial of service (DDoS) attacks: DDoS attacks have assumed increasing significance in recent years.

Common Criteria for Information Technology Security Evaluation: The Common Criteria have become the international framework for expressing security requirements and evaluating products and implementations.

Online appendices: Six appendices available at this book's Web site supplement the material in the text.

In addition, much of the other material in the book has been updated and revised.
