It is the purpose of this book to provide a practical Survey of both the princoples and practice of cryptography and network security. In the first two parts of the book, the basic issues to be addressed by a network security are explored by providing 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.
The subject, and therefore this book. Draws on a variety of disciplines. In particular, it is impossible to appreciate the signifucance of some of the techniques discussed in this book with out a basic uderstanding of number theory and some resuls from probability theory. Nevertheless, an attempt has been made to make the book self-contained. The book present not only the basic mathematical results that are needed but provides the reader with an intuitive undertanding of those results. Such backgruond material is introduced as needed. This appoach helps to motivate the material that is introduced. And the author considers this preferable to simply presenting all of the mathematical material in a lump at the beginning of the book.
