Foreword - 2

The book Cryptography and Network Security integrates insights about modern cryptography techniques and their underlying mathematical foundations. This is evident from the rich literature on mathematical illustrations and applications of the various layers of network, as detailed in the book. Anyone interested in security protocol development in the sensitive application domain would find Cryptography and Network Security unique in its methodology and would be enlightened by its contents. Discussions on classical encryption techniques, advanced encryption standard, public key cryptography, elliptic curve cryptography, digital signature algorithms and authentication applications, network security, IP security and application layer security are the major highlights of the book. The book is a repository of wonderful examples and programming exercises in Java based on the learning experience of the authors themselves and the influence of their students and peers on them.

This book ends with a complete glossary and references related to security and authentication. The security exemplars described in the book are inspirational and reveal that gifted individuals can make a difference in the security world. Cryptography and Network Security provides a roadmap to channel and learn authentication schemes and security standards and is indeed a treasure for gifted young students, faculty and the research scholars. Teachers will find this volume a gold mine of effective classroom strategies that could be used to develop the selected domain. The authors have done a commendable job of making complex concepts accessible to any kind of reader.
