Applied Cryptography for Cyber Security and Defense: Information Encryption and Cyphering applies the principles of cryptographic systems to real-world scenarios, explaining how cryptography can protect businesses' information and ensure privacy for their networks and databases. It delves into the specific security requirements within various emerging application areas and discusses procedures for engineering cryptography into system design and implementation.

Exploring techniques and tools and best practices used in the real world. KEY FEATURES ● Explore private and public key-based solutions and their applications in the real world. ● Learn about security protocols implemented at various TCP/IP stack layers. ● Insight on types of ciphers, their modes, and implementation issues. DESCRIPTION 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. WHAT YOU WILL LEARN ● Describe and show real-world connections of cryptography and applications of cryptography and secure hash functions. ● How one can deploy User Authentication, Digital Signatures, and AES Encryption process. ● How the real-world protocols operate in practice and their theoretical implications. ● Describe different types of ciphers, exploit their modes for solving problems, and finding their implementation issues in system security. ● Explore transport layer security, IP security, and wireless security. WHO THIS BOOK IS FOR This book is for security professionals, network engineers, IT managers, students, and teachers who are interested in learning Cryptography and Network Security.

Starting with the historical evolution of computer and communications networks and their security, the book then arrives at the main definitions of cryptography and network security. Next, the basics of information theory, how to measure information, the information associated with a certain source are also discussed. Source codes are presented, along with the concepts of information transmission, joint information, conditional entropy, mutual information and channel capacity. Computer networks are discussed, including the main protocols and network architectures, and the important TCP/IP protocol. Network security, a topic intrinsically connected to computer networks and the Internet, is presented, along with information about basic hacker attacks, alternatives to prevent attacks, data protection and secure protocols. The information theoretical aspects of cryptography are described including the hash function. An appendix includes a review of probability theory. Illustrations and graphics will help the reader understand the theory.
