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.

Summary

In this chapter, we introduced the basic principles of homomorphic encryption and its fundamental bases, and we analyzed the partial homomorphism in RSA.

After that, we explored the math behind search engines and, in particular, Eulerian circuits. We then undertook a deep dive into trees (graph theory), experimenting with a particular tree graph construction such as Huffman code. If usefully combined with hash trees and other elements, this algorithm is an excellent candidate for searching and compressing data in unstructured content.

Finally, we analyzed CSE, looking at its principal elements and possible future applications.

You have now learned what CSE is and how it is implemented.

Now that you have learned the CSE fundamentals and have explored most of the main cryptographic algorithms, I wish to congratulate you. I hope that this book will be helpful in your career and your professional life.
