Cryptography and Network Security: Principles and Practice, Global Edition, 8th edition

For courses in Cryptography, Computer Security, and Network Security.

Keep pace with the fast-moving field of cryptography and network security

Stallings’ Cryptography and Network Security: Principles and Practice introduces students to the compelling and evolving field of cryptography and network security. In an age of viruses and hackers, electronic eavesdropping, and electronic fraud on a global scale, security is paramount. The purpose of this book is to provide a practical survey of both the principles and practice of cryptography and network security. The first part of the book explores the basic issues to be addressed by a network security capability and provides a tutorial and survey of cryptography and network security technology. The latter part of the book deals with the practice of network security, covering practical applications that have been implemented and are in use to provide network security.

The 8^th Edition captures innovations and improvements in cryptography and network security, while maintaining broad and comprehensive coverage of the entire field. In many places, the narrative has been clarified and tightened, and illustrations have been improved based on extensive reviews by professors who teach the subject and by professionals working in the field.

Hallmark Features

• NEW: Chapter 1 includes a new section describing trust and trustworthiness—two key concepts in computer and network security.
• NEW and EXPANDED: Coverage of Cloud security; IoT network security; and treatment of stream ciphers to keep pace with their growing importance.
• NEW: Two new sections cover:
  • Rapidly emerging topic of lightweight cryptography in response to the Internet of Things and other small embedded systems that require new approaches to cryptography to accommodate the low power requirements, minimum memory, and limited processing power of IoT devices.
  • Post-quantum cryptography in anticipation of the potential threat posed by quantum computers based on considerable research and development of cryptographic algorithms that are resistant to the threat.

• Fundamental security design principles in Chapter 1 include a section discussing the security design principles listed as fundamental by the National Centers of Academic Excellence in Information Assurance/Cyber Defense. This is jointly sponsored by the U.S. National Security Agency and the U.S. Department of Homeland Security.
• A unified, comprehensive treatment of mutual trust topics explores key management and user authentication, which are fundamental to the successful use of cryptographic services. This treatment gives the student a systematic and comprehensive understanding of the issues involved.
• A solid yet easy-to-follow mathematical background provides an intuitive understanding of the basic mathematical results given in the book. Coverage of number theory and finite fields, including numerous worked-out examples, make the abstract subject matter clear.

• Sage cryptographic algorithms provide numerous examples and are used as the basis for hands-on assignments, offering unmatched means for students to learn this subject.
• Comprehensive, up-to-date surveys of cryptographic algorithms provide an understanding of the important cryptographic algorithms and allow students to assess their relative strengths and weaknesses.
• Complete coverage of authentication and digital signatures enables students to compare and evaluate competing approaches to understand each approach better.
• Coverage of both PGP and S/MIME for electronic mail security explores the two most important approaches to email security, giving the student an understanding of both schemes at a detailed technical level.
