About

Features

Use of Sage to illustrate cryptographic algorithms.

The Sage computer algebra system is used to provide numerous examples of cryptographic algorithms and is also used as the basis for numerous hands-on assignments. This is an unmatched means for students to learn this subject. See Appendices B and C.

Comprehensive up-to-date survey of cryptographic algorithms.   

The student gains an understanding of all of important cryptographic algorithms and is able to assess their relative strengths and weaknesses. See Parts One, Two, and Three.

Complete coverage of authentication and digital signatures.         

Enables the student to compare and evaluate competing approaches, and thus understand each better. See Chapters 12 and 13 cover these topics.

Unified, comprehensive treatment of mutual trust topics.  

Key management and user authentication are fundamental to the successful use of cryptographic services. This treatment gives the student a systematic and comprehensive understanding of the issues involved. See Part Four.

Excellent collection of homework problems.           

Approximately 300 problems reinforce material in the text and also introduce new concepts and techniques. Problems are included at the end of each chapter.

Solid yet easy-to-follow mathematical background.           

It is impossible to assess the relative strengths of various approaches without some understanding of number theory and probability. The book requires no prior math background and gives the student a clear understanding of the math required. Chapters 4 and 8 cover number theory and finite fields including numerous worked-out examples to make this abstract subject clear.

Comprehensive, up-to-date coverage of IP Security.         

IPSec is one of the most complex and one of the most important of the new network security standards. This book gives a clear and detailed technical treatment. Chapter 19 is devoted to IPSec.

Comprehensive, up-to-date coverage of wireless network Security.        

The student gains an understanding of the importance of this topic. Chapter 17 is devoted to this topic.

Coverage of both PGP and S/MIME for electronic mail security.   

These are the two most important approaches to email security. The book gives the student an understanding of both schemes at a detailed technical level. Chapter 18 is devoted to PGP and S/MIME.

Unequalled support for projects.      

For many instructors, an important component of a course is a project or set of projects by which the student gets hands-on experience to reinforce concepts from the text. The book provides unparalleled support for including a projects component with the course. The Instructor's Manual includes guidance on how to assign and structure the projects and includes a set of suggested projects that covers a broad range of topics from the text. The following types of projects are supported in the Instructor's Manual:

  • Hacking Assignments: A series of hacking problems for the student to experiment with.
  • Block Cipher Projects: These give the student greater understanding of AES, DES, and modes of operation.
  • Programming Projects: The instructor's manual includes a series of small programming projects that cover a broad range of topics, and that can be implemented in any suitable language on any platform.
  • Research Projects: A series of research assignments that instruct the student to research a particular topic on the Internet and write a report.
  • Practical Security Assessments: A set of exercises to examine current infrastructure and practices of an existing organization.
  • Reading/Report Assignments: A list of papers in the literature that can be assigned for the student to read and then write a short report.
  • Writing Assignments: Designed to engage the student in a deep understanding of the topic and to reinforce their knowledge of hard facts and problem solving techniques.

Unequalled support for instructors and students

  • The book includes 300 homework problems with a range of difficulty plus numerous review questions; the Instructor's Solutions Manual contains solutions to all problems and questions.
  • A Computerized Test Generator is provided.
  • The book makes liberal use of figures and tables to clarify concepts.
  • List of key words, recommended reading list, and recommended Web sites at the end of each chapter.
  • Glossary.
  • List of acronyms on back endpaper.
  • Up-to-date bibliography at end of book.
  • An Internet mailing list has been set up so that instructors using this book can exchange information, suggestions, and questions with each other and the author. Sign-up information for the mailing list is provided at the Web site.
  • See the Features and Supplements sections for more information.

Comprehensive and unified discussion of intruders and viruses.   

The threats of intruders (hackers) and viruses are distinct, but there are also similarities. By treating the two in the same chapter and in a unified way, the student gains greater understanding of both topics. See Chapter 15.

Expanded Homework problems.

The number of problems has been expanded from 239 in the fourth edition to 301 in the fifth edition. In addition, there is a new set of problems plus solutions available to students online.

William Stallings' Cryptography and Network Security: Principles and Practice, 5e is a practical survey of cryptography and network security with unmatched support for instructors and students.

In this age of universal electronic connectivity, viruses and hackers, electronic eavesdropping, and electronic fraud, security is paramount. This text provides a practical survey of both the principles and practice of cryptography and network security. First, the basic issues to be addressed by a network security capability are explored through a tutorial and survey of cryptography and network security technology. Then, the practice of network security is explored via practical applications that have been implemented and are in use today. An unparalleled support package for instructors and students ensures a successful teaching and learning experience.

The new edition has been updated to include coverage of the latest topics including expanded coverage of block cipher modes of operation, including authenticated encryption; revised and expanded coverage of AES; expanded coverage of pseudorandom number generation; new coverage of federated identity, HTTPS, Secure Shell (SSH) and wireless network security; completely rewritten and updated coverage of IPsec; and a new chapter on legal and ethical issues.
