Cryptography and Network Security: Principles and Practice, 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 introduces students to the compelling and evolving field of cryptography and network security. The purpose of this book is to provide a practical survey of both the principles and practice of cryptography and network security.

The 8th 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 instructors in the field.

Hallmark features of this title

• Fundamental security design principles in Chapter 1 include a section discussing those 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.
• A solid yet easy-to-follow mathematical background provides a foundation to assess the relative strengths of various approaches without needing a prior understanding of number theory and probability, while giving students a clear understanding of the math required.

New and updated features of this title

Keeping pace with innovations in the field

• NEW: Chapter 1 includes a new section describing trust and trustworthiness: two key concepts in computer and network security.
• NEW: Coverage of Cloud security, IoT network security and treatment of stream ciphers helps students 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.
