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.

Chapter 6: New Algorithms in Public/Private Key Cryptography

In 2001, I met a person who played an important role in my professional life; his pseudonym is Terenzio.

It was a sunny summer day; Terenzio was going back and forth running toward a tube slide and then into a swimming pool. I was reading a journal in the shade when I heard a particular voice that repeated some strange mathematical formulas. Time after time, Terenzio passed near me after jumping into the swimming pool. Terenzio is an autistic guy, and he suffers from dyslexia, which affects his speech. However, mother nature gave him a big gift; he can literally see big numbers in his mind, and in particular, prime numbers. We became friends, and I investigated his formulas. I have to be grateful to Terenzio even though I am writing this book on cryptography. The inventions I have created during my 20-year career are dedicated to, and in part are the merit of, Terenzio.

In Chapter 5, Introduction to Zero-Knowledge...
