Cryptography and Network Security: Principles and Practice

Cryptography and Network Security Principles and Practice pdf

Stallings’ Cryptography and Network Security,  introduces the reader 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. In the first part 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.
