Cryptography and network security : principles and practice Stallings, William

Pearson brings to you the revised edition of Cryptography and Network Security by Stallings. 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. In the first part of the book, the basic issues to be addressed by 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.Features1. Throughout the book, refinements and revisions improve pedagogy and user-friendliness, in addition to substantive changes.2. Comprehensive, up-to-date surveys of cryptographic algorithms provide an understanding of the important algorithms and allow students to assess their relative strengths and weaknesses.3. New sections on fundamental security design principles, attack surfaces and attack trees.4. Chapter on Email Security has been completely rewritten to provide a comprehensive and up to-date discussion of the topic.5. Discussion on user authentication model, cloud security and Transport Layer Security has been thoroughly reorganized and expanded in the new edition to reflect recent developments.
