Cryptography has proven to be one of the most contentious areas in modern society. For some, it protects the rights of individuals to privacy and security. For others, it puts up barriers against the protection of our society. This book aims to develop a deep understanding of cryptography and provide understanding of how privacy, identity provision, and integrity can be enhanced with the usage of encryption. The book has many novel features including: full provision of web-based material on almost every topic covered; provision of additional on-line material such as videos, source code, and labs; and coverage of emerging areas such as Blockchain, Light-weight Cryptography, and Zero-knowledge Proofs. Key areas covered include: Fundamentals of Encryption, Public Key Encryption, Symmetric Key Encryption, Hashing Methods, Key Exchange Methods, Digital Certificates and Authentication, Tunneling, Crypto Cracking, Light-weight Cryptography, Blockchain, and Zero-knowledge Proofs. This book provides extensive support through the associated website of: http://asecuritysite.com/encryption

Graphs can be used to model many types of relations and process dynamics in physical, biological, social and information systems. Many practical problems can be represented by graphs. In this book, the authors present new research on graph theory including the applications of graph theory in architectural analysis; Miesian intersections and comparing and evaluating graph theory approaches to architectural spatial analysis; the algebraic structure of graphs; the combination of graph theory and unsupervised learning applied to social data mining; organizing and structuring the contents of mathematical subjects using graph theory; and a modularity-based filtering approach for network immunization.

Almost every student has to study some sort of mathematical proofs, whether it be in geometry, trigonometry, or with higher-level topics. In addition, mathematical theorems have become an interesting course for many students outside of the mathematical arena, purely for the reasoning and logic that is needed to complete them. Therefore, it is not uncommon to have philosophy and law students grappling with proofs. This book is the perfect resource for demystifying the techniques and principles that govern the mathematical proof area, and is done with the standard "Demystified" level, questions and answers, and accessibility.
