Cryptography Algorithms

By: Massimo Bertaccini

Overview of this book

Cryptography Algorithms is designed to help you get up and running with modern cryptography algorithms. You'll not only explore old and modern security practices but also discover practical examples of implementing them effectively. The book starts with an overview of cryptography, exploring key concepts including popular classical symmetric and asymmetric algorithms, protocol standards, and more. You'll also cover everything from building crypto codes to breaking them. In addition to this, the book will help you to understand the difference between various types of digital signatures. As you advance, you will become well-versed with the new-age cryptography algorithms and protocols such as public and private key cryptography, zero-knowledge protocols, elliptic curves, quantum cryptography, and homomorphic encryption. Finally, you'll be able to apply the knowledge you've gained with the help of practical examples and use cases. By the end of this cryptography book, you will be well-versed with modern cryptography and be able to effectively apply it to security applications.

The innovation in CSE

CSE represents a technological solution based on isomorphism, a transformation that preserves information, as it can offer searching, browsing, and manipulation on encrypted data, that is, with zero knowledge; encrypted, sensitive data stored on public cloud providers will eventually be fully accessible by data owners only, still allowing cloud providers to offer searching, browsing, and manipulation over encrypted data by means of encrypted queries, thereby preserving the zero knowledge. CSE is able to operate independently according to the kind of encryption that the user decides to adopt. On the one hand, private users could take back legitimate ownership of the value of their data and eventually trade it back to service providers through a fair deal, which is very different from the take-it-or-leave-it approach that we currently witness; this is a key value for the next generation of digital citizens who could also exchange or sell their data autonomously...
