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 8: Quantum Cryptography

In this chapter, I will explain the basics of quantum mechanics (Q-Mechanics) and quantum cryptography (Q-Cryptography). These topics require some knowledge of physics, modular mathematics, cryptography, and logic.

Q-Mechanics deals with phenomena that are outside the range of an ordinary human's experience. So, it might be difficult for most people to understand and believe this theory. First, we will start by introducing the bizarre world of Q-Mechanics and then examine Q-Cryptography, which is a direct consequence of this theory. We will also analyze quantum computing and Shor's algorithm before looking at which algorithms are candidates for post-Q-Cryptography.

So, in this chapter, we will cover the following topics:

  • Introduction to Q-Mechanics and Q-Cryptography
  • An imaginary experiment to understand the elements of Q-Mechanics
  • An experiment on quantum money and quantum key distribution (BB84)
  • Quantum computing...
