Cryptography and Network Security teaches you everything about cryptography and how to make its best use for both, network and internet security. To begin with, you will learn to explore security goals, the architecture, its complete mechanisms, and the standard operational model.

You will learn some of the most commonly used terminologies in cryptography such as substitution, and transposition. While you learn the key concepts, you will also explore the difference between symmetric and asymmetric ciphers, block and stream ciphers, and monoalphabetic and polyalphabetic ciphers. This book also focuses on digital signatures and digital signing methods, AES encryption processing, public key algorithms, and how to encrypt and generate MACs. You will also learn about the most important real-world protocol called Kerberos and see how public key certificates are deployed to solve public key-related problems. Real-world protocols such as PGP, SMIME, TLS, and IPsec Rand 802.11i are also covered in detail.

Cryptography and Network Security has been a subject in computer and IT engineering syllabus since decades. Over the period of time the reliance of the users over web and other electronic media has increased to such an extent that this has becomes one of the most popular subjects in computer science and engineering discipline. Cryptography is not the only part of security processing, there are quite a few other aspects, including how one can make sure our documents remain safe, how the sender of a content is authorized and authenticated, how the Internet protocols enable secure operations of the data traveling across and so on. The book covers them as well.

The idea of presenting complex content by using an inductive approach is the key feature of this book. Many real world examples are presented to illustrate the theoretical ideas. The stress on ‘why’ aspect of content is also dully addressed which makes this text quite unique. In short, the book combines real-world practical examples with important theoretical ideas along with proper reasoning.
